Well, The junk yards in my area (pick n pull) are loaded with turbo vehicles at the moment... Volvo's with Garrett's and DSM's Supra's I think i may want to aquire something from there. Along with Volvo Cuplers which i think are the best.

Im only shooting for a solid safe 350 HP

Im about to just slap this together and run it. but if anyone has any opinions or advise here is what is running though my head.

I want to do twin turbo. I am indecisive of what size turbos i (want/need) to run. there is 2 supras with ct26's with good shaft play..

I keep asking my self-

-How (well/long) will my 120k 5.0 engine will last if i do this?

-Should i convert to TPI? or should i stay TBI?

-What Injectors i will need.

- How much HP Can my block take. (pistons?/rods?/crank?) Should i or

-Do i really really have to change anything? or can i run TT on a stock block

-Megasquirt

 

over on turboforums.com there's a section on junkyard turbo's

if your already tbi, i'd look into EBL. it will save you money converting to tpi and buying megsquirt. and most likely end up better.

the stock motor seems to be ok from what i read if you stay safe with the tune and around 10psi with an intercooler.

also while your on turboforums, go to the gm setion and read about how fast a guy went with a dead stock junk yard 350. he did run race gas, but in the end, it seems to be all about not rattling the motor. even a high dollar built motor wont like it for long.


then come back here and make a thread so we can all follow along with your build. its enjoyable to read, since i can't do it yet. i'm still stuck with a supercharger for a while.

 

You could pretty much answer all your questions with ‘it depends.’ Even the _best_ answer will really depend on what you want to accomplish and how you want to do it, without more detail, no one is going to be able to give you the best answer, and anyone giving you one specific answer is someone giving you what they would want out of it… that said:

Yes/no/maybe… what condition is it in? We’ve all seen engines dead before 120K, and they have survived past 250K… how has it been taken care of? What shape is it in?

Why? If you have a reason to or want to sure… if not then no. I could give good reasons for and against turbocharging a TBI, and it’s limitations aren’t that big a deal with your relatively modest power goals.

TBI or TPI? How are you adding fuel (ECM control, FMU, auxiliary injectors, N2O fuel nossle…)?

More than 350hp with careful tuning and reasonable care, OTOH, without it you could kill it with 100hp…

If you want, you don’t have to. I just put together one but I have much more lofty goals and even then it’s not the only way to get where I want to go…

 

Well then im am set as a of goals.. Im not to sure what condition my engine is in.. i got it with 90 k and then drove it around for 4 years.. I took good car of the block with oil changes.. and fixing what ever broke..

Im gonna start out with converting to TPI so that i can run some bigger injectors and i will have 8 of them. Its easyier for me to find top mounted injectors at the junkyard.

Im going with a walbro fuel pump

Some Supra 440's or some modified DSM have some nice injectors That i also see at the junkyard will also be an Option. Those Merkurs X4Rti wierd cars have nice injectors as well. I still need to find out if i am going to be high impedance or Low impedance - i really dont know what TPI has.. Im not sure if i may need a resistor pack or not.. i can aquire those.

And as far as EFM's or FMU im sure i will take one shot and go megasquirt. This way anything else i plan to do or with other motors i have somthing to tune it with and i can update it as well. (Anyone have one for sale?) i may wanna by after the new year. I may have bigger horse power goals after i finish this.

Ive been collecting Volvo Cuplers. i belive they are the best.

For the exhaust manifolds im going to use my stock ones and fab the flanges on.

Turbos i will be running 2 CT26's or some TD04H's im only planning to safe PSI like 8 -12 psi

I will be running an IC from ebay i found that has a duel inlet and single outlet.
32.5" x 11.75" x 2.75" cant beat 80 bucks.

Ive been collecting some exhaust piping for my plumbing for my intake. with limited tools ive learned to cut at angles from a strait section. and shift them to make a bend in the piping which will look like pie cuts later.. i like the way it looks..

as soon as this rain clears up i will post up on what i have aquired.. so far i have spent nothing on this build. and what i do have at the moment is

-Piping
-cuplers.
-manifold
-flanges


thanks for the advice guys!

 

FWIW, I'm still running the stock fuel pump on my 5.7 at 9.5 psi. Certainly the Walbro is a good plan, but doesn't have to be the first thing you buy - not to mention the chore of installing on in a third gen! At any rate, I think the stock is fine up to about 7 psi.

TPI injectors are high impedance. The Megasquirt can handle either, but high impedance injectors are slightly easier to configure (there is a flyback board you should add for low impedance injectors to enable better control)

 

That was so helpfull thank you... i really wasnt looking forward to doing the fuel pump. although if i did.. i was gonna make an entry way from the inside.. so i can lock and unlock it to.. but thats great.. once my build is complete i will test from low boost and see what happends with my stock fuel pump.. does anyone know about this code 59 thing ive heard about it only with people trying to run turbos.. i dont understand what they are talking about.

 

I started with Code 59 and it was going pretty well until I put in my bigger injectors. I spent a couple of months fighting with it and eproms and romulators and finally went to the megasquirt. I had a lot of problems, from Tuner Pro RT (the software you need to edit Code 59) crashing to breaking down in the middle of an intersection because I updated the BIN into the romulator (sitting at a red light) and the ECM shut down. Not fun!

Now I'm not gonna knock Code 59 too much. Afterall, Orr89RocZ is running mid 9's with Code 59. It has endless options and all of the benefits of the stock ECM, such as EGR, cannister purge, desired idle RPM and so on.

Megasquirt fails to impress on these very basic nescessities of a true street machine. Things like not knowing your mph, not knowing the AC clutch is on and not being able to set desired idle RPM really SUCK! However, the real time programming and autotune features on the megasquirt and the fact that Code 59 would not cooperate ultimately won me over.

Also you have the option of using your stock ECM alongside the Megasquirt to control things that the megasquirt doesn't. I'm seriously thinking about putting a factory ecm in for controlling the idle, cannister purge and the fans. I've also thought about using a later model ECM for this so I have the option of going to a 4L60e transmission. Tired of chasing the perfect shift points with this old fashioned governer!

 

im kind of interested in doing this. what all would be involved n running low boost like 5-7. i just want alittle kick to the car

 

Okay but when does this code 59 happen or damn i dont know how to ask this question.. is it somthing that comes on when you run bigger injectors with TPI or is it somthing you have to trigger to have certain operations?? sorry im really slow at these kind of things but im trying.. if i go megasquirt am i gonna have to worry about this..

 

The best advice i can give you is

1. Asking your self weather you wanna go single or twin turbo.

2. what stock turbos will run what you want and how much PSI or HP are they good for.

3. figure out:
(a)Exhaust manifolds / Tubo manifolds (im building mine so i can place the turbos where i want then which is in the front away from my belts and accessories)


(B) when you figure out what turbos you wanna use, is the turbo gonna be cooled by oil or coolant - and then figure out how you are gonna run the lines and from where. sounds big but not that bad be creative.

(C) Intake Plumbing / Intercooler {IC}
4) what stock waste gates and blow of valves will be sufficient for your 5-7 PSI

5) you wont have to worry about using a different fuel pump. unless you are gonna boost more than like 8-9 PSI

I hope im correct please correct me if im wrong.. this is just getting the skeleton of a turbo system..

(6) Read this : http://www.turbobygarrett.com/turbob...o_tech101.html

 

This is a must, maybe a TPI fuel pump can cutt it, but a TBI fuel pump is maxed out at around 15psi. Even keeping TBI will require a higflow fuel pump for your power goal.
Stock TPI injectors require around 41-47 psi for stock power.

 

Good point Thomas! I forgot about him starting with TBI. Looks like he'll be starting with that Walbro afterall.

It is a different program you burn into your factory prom (or into a Romulator). Best place to start is http://www.code59.org

 

I am running the code $59...its just a modified GMC syclone/typhoon turbo truck code that can be used to run boosted V8's. It took me awhile to figure out how to use it all and i was fighting some idle issues but after some time of playing with it, i got a fairly stable idle with BIG 80lb injectors, high impedance. I dont have EGR or torque converter lockup anymore so i dont know how well those features work. There are alot of things in this code that I dont understand nor will I have use for as its designed for turbo trucks with alot of stuff our cars dont have i guess.

No worries tho, just understand the basics and it will work fine. I dont use romulator, i just burn chips which requires stopping the car. I make logs with tunerpro rt and then read through and then make necessary changes. Burn and drive again to see how it reacts. My car made 640whp on a mustang dyno with a fat tune through a VERY loose converter on 12.5 psi. It will trap 140 mph in the 1/4 on 13-14 psi. I got a strong feeling once i get my issues with backpressure and converter figured out, I will approach 700+whp on 14psi which i run at the track and 800 on higher boost levels.

For your goals, code 59 should easily work but will take some time to dial in unless you actually find a base bin that works for your motor. I started from scratch basically, as I took the 60lb injector truck base bin and scaled it down to be close to my 80 lb injectors...then started from there. Took alot of changes but like i said, give it time and think through the process to understand the solutions to the problems you encounter, and it will make sense to you.

 

A thing I do not understand, is why you guy's running turbos dont know/use EBL flash yet.
The repinning of the TPI harness for the EBL is not complicated and well documented.

 

The EBL is priced way too high for a bottom of the barrel ECM with some hardware updates. It is old technology and not worth the money. The 730/749 ECM for $50 will do everything and more compared to the EBL. The EBL is good for TBI guys that are afraid to re-pin a harness to a later and better ECM.
It is like throwing out your XBOX 360 and replacing it with a 1980's ATARI system with a CD player upgrade.

 

Yeah I have no idea what the EBL was or is, but i always thought it was a TBI thing since i have seen it mentioned in TBI threads.

I started with a TPI 89 MAF car, repinned that to 730 SD and got a ecm for 25 bucks Wasnt hard to repin that harness either. I was intimidated at first but it wasnt bad at all. For the price of this swap you cant complain. I got a 25 dollar ECM running a 12K+ dollar 800+ hp 9 second twin turbo motor haha.

 

junkcltr,

Your statement sounds a little exagerated, considering that EBL has everithing to handel boost, cold air, WB02 sensor, ...

But since you are the one running turbo you must know whats best.

 

The EBL is liked by the TBI guys because of the user interface on the PC side. The EBL base ECM is slow and out dated. The EBL is a hardware piece added onto the old ECM to make it do almost all the stuff a 730 ECM will do. But it costs $300 instead of $50.

The 730 / 749 ECM gets a bad name with boost sometimes because of improper tuning. People put a romulator or Moates thing in there with the TunerPro software to tune thinking that real time tuning is the way to go. Little do they know the bugs in TunerPro and the romulator / Moates things are not designed that well and cause problems. They think it is the ECM and code while the entire time it is the real time tuning stuff causing the problem.
People are in a hurry to get it tuned and try real time, little do they know it is causing them frustration, time, and money.
There are emulators that work reliable. One is made by MonteCarSlow and it is around $50, but it doesn't support the $59 code at this time as far as I know. The other emulator is one that I designed years ago, but barely ever use.

 

yeah, that does seem a bit harsh. i understand it won't control a E trans and a 427 will, but for guys that can't write code, i think the eazy interface, heads up display and mpg display is nice. plus it auto tunes and handles boost. for all but the best of the diy guys, it looks to be a good option to running mega squirt to me. since mega squirt is missing all the things that make for a nice street car efi setup.

 

Tell me exactly what is exagerrated.

The EBL ECM only has 4K of RAM. The 730 has 32K. The EBL ECM has a much slower processor than the 730 ECM. Like 4 times slower. The table resolution is much less. That is expected using a 4x slower processor. The 730 / 749 $59 handles boost cold air, WBO2.

The thing is that the TBI ECM is missing so much stuff that the TPI guys have always had in a stock ECM. The TBI guys think the EBL is great only because it was missing so much from the factory floor.

Just because I am running boost doesn't mean I know what I am talking about.

 

I completely agree that the user interface is great. The real time tuning is great. The hardware for $300 is over priced when you can get a 730 ECM for $50.

EDIT: The $59 code in a 730 ECM is a better setup for boost.

 

what does EBL stand for?

 

well for us normal people, cause i do know you know the code side very well. just looking at money, a 3bar is like 70$ a usb aldl cable is what? 50ish? a ostrich is 175 plus a 30 ish adaptor. and your pretty close to what the ebl cost. and you don't have any of the cool interface. i understand a lot of this can be done in tp5 but i don't know how to yet. and will take a lot of hours reading to learn it.

i added the 3 bar in even though ebl only has a 2bar because 59 needs it. 58 runs a 2bar but no one really likes it for some reason. so for a noob to start out on 58 would be a nightmare.

i don't know what issues the slower processor side of it causes, or at what level you would start to notice it an need more.

but with that said, i've never used ebl, just read about it. 59 works great for me, boosted and n/a. but if i didn't have any tuning tools at all and knew nothing about tuning. i think the ebl is better than mega squirt.

 

I agree with what you said when taking real time tuning into account. Although, I think normal people are better off without real time tuning. They just hack and whack trying to get it right instead of understanding what is actually going on and learning something.

I think the MS-II is better. MS is open source code that the entire world can make better and does. The EBL is a closed source code that only the author can modify. The GM code can by modified by all. That alone gives the EBL a huge disadvantage.
That is just my opinion and doesn't matter to anyone else making an ECM decision. Just some info. for choosing one over the other.

 

embedded lockers.

 

This quote dosent make sense, you trash'n the EBL like its garbage, knowing perfectly that with a repinn the EBL is capable to runn a torbocharged TPI like a champion straight out of the box.

I have intalled EBL in a TPI car and it was perfect, though that time I never heard of MonteCarSlow' module, not sure it was available.

I sure estimate you know wery well that if you dont have the knowledge and opportunity to forge and machine your own pistons, you go shopping or keep walking.

You know how to do all that stuff and even better, Chapeau.

 

Well either system should work fine, but for a budget junkyard turbo build, why spend 300 on EBL when 20-50 bucks for 730 ecm will suffice?

From the original post, this is a budget build so save money on ecm stuff and spend elsewhere

 

Sigle turbovolvo turbo5-7 psi. what ever it gives mewhich would be easier?

 

If 30$ is all it cost to make it happen, I would not even have wondered in first place.

 

well my thought judging by the thread is that, spending the money to buy the tuning stuff and then ending up going ms2 later because you run into trouble that you can't figure out like astro did, in the long run costs you more than just leaving it tbi, plug in ebl and fab up your turbo kit. later on if you dive into tuning and love it. move on to the diy stuff and sell the ebl. they still move in the forsale setion.

but yes, either way. i think most will find the building of the kit harder than the efi side these days.

i will also bring up that for the most part, the ebl thread has pretty good suport for users. while ms2 might as well, the diy ecm's are more we will help you learn as you go, but its up to you to read and make sense of it. many long headache causing hours later. it kinda makes sense. or atleast we mostly muddle thru it till it runs about right.

 

just the map sensor is 70 alone, since he's tbi. good luck finding a good AUJP memcal to swap into that cheap ecm. as well as the aldl cable and adaptor board for hold the chip.

you might get a ecm for 30$, my junkyard wants 50$ but unless you have everything else, you aint doing nothing with it.

 

Exactly.

 

Since this thread has been brought to my attention, all I can say is that every single statement is false.

Of course with the exception of your closing statement...

RBob.

 

If you convert to TPI it gives more fuel adjustability, but since you only want 350HP then it may not be worth it. Going TPI has the benefit of using an off the shelf ECM and widely available fuel injectors. It allows for easier upgrades down the road.

For 350bhp you need 30 #/hr injectors at a minimum with stock fuel pressure assuming a stock TPI engine bsfc with a turbo on it. You should be able to find them in the yard or cheap on Ebay. The classifieds usually have TPI setups for $150 or less. Lots of people swap them for an aftermarket intake. A stock TPI fuel pump will flow enough for 350hp at the stock fuel pressure.

For a budget setup wanting 350HP I would not spend the money on injectors and go with a Walbro TPI fuel pump at a higher fuel pressure using widely available 24#/hr injectors. You can just about get them for free because they came on so many engines. Running the fuel pressure around 55PSI with the Walbro pump with support your HP goal.

TPI intake $150
Walbro pump $110
Adjustable fuel regulator (free), weld a screw to the stock TPI FPR
730 ECM ebay/junkyard ($50), use v6 memcal with like bore size, add jumper wire
2 late model junkyard turbos with at least a 37mm inducer (a pair of volvo or saab GT17s would do it)

You can go the TBI route, but the upgrade parts will cost more in the end.

 

I guess you don't have to be a TGO supporter to put a link in your signature to your company. I thought that was against the rules?

I was hoping you were going to help the original poster with info. on his quest to add a turbo to his TBI engine.

 

????(awkward)
Hehe.. uhm.. woah..

Yeah so... im going TPI for sure like i said before.. uhm... fuel adjustability.. and i hope to run more than 350hp some day.. 350hp was just my first attempt for turboing my chicken in a safe mode attempt. so in the event that i see to adding more boost or head or block mods, i know i will be able to stick with TPI. and i like the way it looks and its cheap to swap!!

im planning for Future advancement after my experimental stage... so i bought the walbro as that will for sure be enough for any amount of fuel i want to push or need to push...
In addition to the future planning of this experimental journey, i have reasearched that MS-2 will be somthing to invest in during the stages of increasing HP starting from 350HP. And i know that i will be able to utilize it for many years to come. And the PnP is a plus..

I sold my K5 blazer for $850 and have taken care of my Registration... and 6 months of insurance.. i will need a smog to aquire tags to be mobile... and i will start the fabing next week wednesday... i will refer to this thread many times.. i thank you for your advice and your support!

Oh! there is somthing i wanted to ask but im brain farting. somthing about injectors.. .. i will have to come back and ask.... Updates will be comming soon.. hopfully if this rain goes away!!! :P

 

Now that's funny. I am helping everyone that reads this thread by stating flat out that every thing that you have said regarding the EBL is false. It's that easy to help out folks that are looking for input.

RBob.

 

Nah, it's true. I recommend you read what I wrote more closely. I never said anything about the EBL in what you quoted. I specifically said it about the EBL ECM. Nothing about the EBL itself. You simply misunderstood.
What I said about the EBL itself is that it has a good user interface and real time tuning support. Of course, you didn't quote that though. The bad part is the cost because it just upgrades an old outdated slow TBI ECM to the speed of a better ECM.
If you want to clearly state how the EBL is better than a 730/749 with $59 code and the MS-II then I think that would help the original poster. I think that would help a lot of people trying to decide between the ECMs and code. Why not include the 427 ECM also in the comparison.

Why didn't you quote what I wrote about the signature part with a link to your company website? Your posts normally have the link in the signature but for some reason that one didn't. The others do.

EDIT: If you compared the EBL to the 427 ECM........why not just make a real time module for the 427 ECM and ditch the EBL all together. The 427 has everything the old 747 was missing except for real time programming. At least this way you would be able to sell it to the 4L60E/4L80E people too. It would help in marketing and selling product.

 

Yeah, people selling products around here don't like when they are compared to other products. The EBL is a good product, just not worth the money for what it does when used with a TPI setup. On a boosted TBI setup it is a toss up between that and the MS-II.......although, I do have some boosted $0D code in a GM 427 ECM that uses both a N/A map and 3_bar diesel map sensor that you can pick up for under $20. I probably shouldn't bring up another ECM at this point though. ha ha

Good call on getting the Walbro pump. If you go with the adjustable fuel regulator it will not be lost money if you upgrade the injectors later. Both the $59 code and MS-II will do what you need it to. If you go with the $59 code then get a Willem programmer and a few chips to program. The MS-II does real time programming.

 

Since you are in California with the stringent smog requirements, be careful of which ECM you choose to go with. At a minimum the ECM will need to control closed loop fueling for the cat, CCP for canister purge, and EGR for NOX reduction.

I'm not sure about this next part, but in Cali can you alter the exhaust prior to the cat? If not then a rear mount turbo is a good choice.

Take your time and do some serious research before jumping in. It is all too easy to end up with a project that has been started and can't be completed with a street driven car.

RBob.

 

Not at all. The issue is when you do the comparison you did not state the facts. You just rambled on about how slow and outdated the ECM is and that the resolution is bad and the tables are bad because the EBL can't keep up, blah, blah, blah.

As far as your boost code on all these other 'fine' ECMs, big deal. Since you won't release the source code they aren't worth a hill of beans.

Which in turn takes us to open code where anyone can modify it. Again, big deal. How many people can modify source code? How many people building engines that want to tune them also want to learn how to modify the code? About 1 in 10,000, maybe?

You said what you said about the EBL, it is here for all to read. And now you toss out red-herrings to try to make it look like you didn't.

jbucago, I now return you to your normally scheduled thread. Let us know how you make out along the way.

RBob.

 

It is clear that one goal of the EBL was to speed up that old slow outdated ECM. The EBL was to make it as fast as the better ECMs made at that time. GM had the "B" team design the TBI hardware and software back then. We all know that. Compare the 1990 TBI code to the 1990 TPI code........pretty obvious the "B" team did the TBI code and hardware and the "A" team did the TPI code and hardware.
How much faster is the EBL than a 749 ECM? How much better are the tables than the $59 code? What makes it worth so much more than the $59 code on a TPI setup?
I had no idea the EBL source code was released? Where can I download it? Or is it not released and is just a hill of beans?
I read what happened with the DIY WBO2 project. I saw what CM did with info. he got from this site to sell buggy emulators. Too many shady people out there looking to make a poor quality product because they don't have the technical know how and just want to make a buck.
I know you have the smarts and your stuff is designed well. As for the TBI ECM from GM. It was junk the day they designed it compared to the TPI ECM.
Let's hear how the EBL installed ECM stacks up against the 'fine' ECMs like the 730/749/427. You keep skating around it.


Lots of people. Take a look at the GNU/POSIX/LINUX project

Yes, I stand by what I said. I chose those words carefully when I wrote it. If you read it hap-hazzard then that is your choice.

We have been talking about mechanical stuff in between the ECM stuff. He decided to go TPI.
That ECM comparison list would be nice for helping with his ECM choice.

Let's stop the run-around and actually technically compare the ECMs? It would help this thread much better than the 'source code released', 'is the EBL ECM or TBI ECM talked about', etc.

 

This is a good point, I dont know how well the $59 code will work with all that stuff. I have no emissions equipment anymore whatsoever... if i did, i'm not sure if the code could control it like it should.

What you need is a boosted 8D code that was talked about here but never given out. I wanted to try it but now that I got the $59 to work, i have no need to change things. But even with that swap, you will need the entire emissions system of the TPI car.

Emissions in Cali may go by original motor setup as stated in the VIN number and not the 'swap' motor, so it wouldnt matter what you had in the car, it wouldnt be legal I dont think. At the very least it would have to meet the TBI emissions standards of that year for that state. I dont understand emissions laws for that region so I dont know what would happen.

I like the idea of TPI over TBI... how many fast boosted TBI setups do you see? I dont know of many. I'm not sure that is the best solution for boosted motors, port injection is best for best air/fuel distribution. I know nothing of the EBL stuff, but if converting to TPI from your current TBI setup is doable, then you should beable to use a 730 ecm and then easily adapt to code $59. Weigh the costs between the two and then look at the long term goals. I had success with $59, thats all i'm saying and I found the swap very easy...although learning how to tune VE/MAP based systems I found difficult at first as i was good with MAF sensors. Once i caught on, it turned out well.

 

The $59 code will do it with flying colors.

A properly tuned open loop ECM will also achieve the results. Reality is that the tech doing the test has no idea what is being controlled by the ECM. Visually stuff must be there and wired up. Of course, the CAT and open loop steady state are not an ideal setup. Putting a full time CAT on a turbo setup just robs so much performance. It would be more of a visual item.

 

I believe the egr is there, but I read somewhere there was an issue with 58 egr and 8 cyl. I don't know if that's true or if its fixed in 59. a highway mod would be nice too. I do wish I knew how it all worked and could help to get the extra board to work with 59 to tune real time thru the aldl port like you can with $8D. but for me 8D's mat alone makes me not want to touch it ever again, if I can help it. I have 59 running sweet on my n/a setup(the one missing fan output kinda sucks, even thou stock 8d cars only used one too) and it was pretty good on my boost car when it was together.(getting parts together to do that lt1 intake/n* dis swap, thanks again guys) plus adding a target a/f table and using it for the wideband in closed loop just isn't going to ever happen in 8d. so wishing for a boosted ver makes no sense at all to me. I spent a year on it n/a and I just plain don't have the brain power to make that code work right on my daily driver 406. the ve table was ok but AE and MAT were always all over the map. from reading about drifting blm's from guys I would think are much better tuners than me. I think a lot ran into these same issues and are just ok with it. because idle is said to be better, even thou there are endless threads about how hard is is making ford green 42# injectors idle clean while 59 is said to not have good idle code, but 42s gave me no issues at all and guys are running high z80# with 59. which is just crazy sounding since I don't think they even made that big of high z injectors a few years ago. so all that better idle code seems to be a little over rated to me, which also maybe why I see ebl as good for me, while it might or might not be the latest and greatest. I would never know it, or prob care. and again, if your building a high hp turbo car, is 300$ to handle the efi side really over priced? seeing as every stand alone is like 2k+

as for where I see diy going, the $0 on the 427 ecm getting more use and hacks, is there's a wideband hack done yet? because everyone wants a 4l80 which I see has its place, like say my stock 96 tahoe that I'd love to swtich to obd1 ecm and make about 5 lbs of boost on. but the price of the efi software (and time), which the softward alone is more than this so called over priced ebl. but anyways. blah, if you don't like to shift gears yourself turbos make enough power to pull 3.08 or lower gears. do you really need an overdrive at that point in you 500+hp car?
and the code59 guys working to make it better and better.

 

HAHA

I saw that California smog was mentioned.. The Build im doing is completely not Legal here in california.. nor would it ever pass smog.. But... I do have friends in the smog industry, and they have been preped and ready to "smog" my vehicle.. im not worried about them... I will be taking all the smog crap out. And deleting the Catalytic converter. if im getting an illegal smog i dont see why im going to need any of it..

As for the TPI maf does anyone know how it measures.. and or if i will need to get somthing aftermarket.. or will the stock TPI maf do fine for the PSI im shooting for..

Then some one mentioned SPeed density to me.. i am unsure of what i will need to do at this point.

Sorry for asking so many questions.. when i start reading the FAQ's i get really lost.. and its hard for me to keep up with the lingo and what not..

 

i was turned on by the fact that i could possibly tune the ecu i already have... I guess all i need is a (programmer) which i stick my eprom in to and then software to tune it.. or there is something i can plug in to my (ALDL) and use a USB to Tune the parameters of my chip.. can anyone make any recommendations/ or what works for you.

what does the Bin File look like.. is it somthing simular to a flash memory card where i can open the tile and "edit the bin file" or is there more in depth than that.. this idea sounds like it will get me by until i get enough money to buy a mega squirt.

Sorry for asking so many questions.. when i start reading the FAQ's i get really lost.. and its hard for me to keep up with the lingo and what not and i dont understand so easy.

 

This sounds really cool looking at the web site looks like this is a possibility.. can you tell me anything about the installation process or the first issues with tuning.. how well do you think this will work with my goals of 350 Hp on this junk yard twin turbo set up... im still trying to figure out how big of injectors i should have.. seeing how i want to aquire injectors that i will be able to utiliez them for more HP later after i get the solid 350hp out of my 5.0 soon to be TPI

 

Now i just need to figure out how im gonna control all this crap.. ECM/EPROM TUNNING ? MEGASQUIRT? i cant decide.. btw i do not want to go TBI...
