Hello there I got a LO5?(350 TBI) still running on 305 throttle body and ECM, everyone says they had problems but when we did the swap and started engine it was fine a Lil rough at idle but that's it. Now I am getting ready to put a 350 throttle body on it and I am going to need a tune now, so I have been looking at all the diff things I can do and honestly ebl flash looks the way to go I jus am wondering A few things...

Learning curve? How hard is it to get into? I don't know anything about tuning.
The flattening of graphs? Looks confusing honestly...

Smog? What to do about smog? I have basically everything smog related still hooked up except the air cleaner.Is there a way I can " tune" so to say for smog? I live in Cali

Diagnostics? How do they work on ebl flash?

And has anyone ever had problems with it? ( as in it doesn't work properly or it goes out very quickly) thank you all for your input

 

Learning curve. yes it take awhile if you have no prior tuning experience.
At bottom of dynamicefi home page is into to tuning 1+2. read that a few times it is very helpfull. also see "free tune' sticky in TBI. good for beginners as it covers tuning basics.

smog? dont know. I would guess it can be ovecome if all the sensors and the catcon is functioning and tune is decent. No guaranties for CA.

diagnostics are in intro part 1.

Had now for 3 years i think. No problems. I have done 100's of flashes and logs with it.

You will get all the support you need and then some.

 

Thank you for your input! And about the learning curve, how long will my car be down? I am young (19) and I work for a real estate firm so I am constantly driving (suckers pay .82cents a mile) so I cannot have my car down long at all. I plan on swapping the throttle body and ebl flash in at the same time either a fri evening or a sat morning and would need my car driving by monday morning. Possible? Thanks ronny

 

There's no down time. Install. Load stock lo5 bin and go from there.

Ebl is the best addition to my Firebird and will probably be the best it ever gets.

My engine runs a lot better/more efficient and has a real noticeable power difference

 

I am extremely happy with mine... originally had moates stuff, but apu1 had so many wires and parts, EBL Flash 1 wire coming out to laptop... you use Tuner pro to change files then upload them into the EBL via the program... I never got around to the moates stuff, but jumped right in with the ebl flash... and customer service is top notch, he will answer, advise, look at a log for you, etc...

My car has been having injector problems, so as a fix, I changed a few things in the tuning so the car keeps running (higher idle, changed value so closed loop doesn't turn on) and now I can drive the car from point a to point be without it shutting down in the middle of the road or a curve... not fun... getting my injectors changed soon and can't wait to tune it and have it run sweet...

 

Just wanted to add a few things. The EBL Flash won't run the A.I.R. system. Can leave it all in place and pop the two terminals/wires out of the harness to ECM connector.

The EGR and CCP are operational. With the right tune it will pass the California sniffer. There are two Cali base calibrations for the L03 f-body, stick & auto. There are also some Caprice L05 calibrations. Although I am not sure whether they are fed or cali, or both.

> Diagnostics? How do they work on ebl flash?

Within the ECM firmware it is similar to the stock GM stuff. Where it checks the sensors and will set a code and use a default value. The What's Up Display has a diagnostic screen that shows the raw sensor values. The data is updated 17 times a second, much faster then the ALDL link.

Thanks all once again for input i just put in my order for my ebl flash i am getting the package already installed with my 88 ECM because soldering... not for me. i am very excited to get my EBL and you guys will see me posting ALOT now asking Q&A on calibration tables ,maps,graphs, ect

 

Good choice. Start reading up there's a lot of info on here and rbob sites

I work on commission right rbob? Haha

 

one thing i am already wondering is the VE learns... i havent got mine yet so i dont know what it looks like but when ever you do your ve learns i know it is attempting to figure out how the engine is running and what to change but how do you save this? i know it will probably be easier to understand when i have infront of me >.< but from what ive read im not sure. and the graphs i dont understand the whole flattening part

 

and luvofjah what is the "closed Loop" you speak... i have seen it before but still not sure

 

You have the "standard" calibrations... The VE learns, it records Volumetric Efficiency, it records what your engine is doing and shows you where tuning can make improvements... So you drive your car for a bit, look at the VE data, tell it to learn, it runs through it and makes adjustments, then you apply them... car runs better...

Closed / Open Loop.... when the car starts cold, it's not taking the oxygen sensor into account, it's running the engine a little rich and high idle to get it going... as it warms up, then reaches a certain temperature (for oxygen sensor to read accurately), it takes it into account and is actually using all the sensors to run / manage... and with that, open loop is cold / start and closed loop is when the engine is warm and all sensors are taken into account...

My car would need to be towed had it not been for the EBL (It's stored away in a garage a few miles from home).... I know I need new injectors, but for now and the tuning the EBL provides I can make it run to get it form point a to b.

Rafael,

Glad to hear you got that thing going. So Ebl has its own "learn" function? Well a basic learn I know everything still needs end user adjustments. But the learn / or auto tuners make initial changes quicker. Does it take input from a WB02?

Also what injectors you need? I have a good set of 24 lb LT1s sitting here in a box.

 

The EBL can use the stock O2 or wide band (of course results / accuracy wold be better with the latter...)

I got a 305 TPI which uses 19, but with the EBL I could stick the 24lbs in there and adjust it I'll pass for now, but thanks, I'm in the process of buying a home with a garage so any work on my car is a few months away...

The EBL has 8 banks, so you can put 8 different tunes in each one and flip from one to another with a simple mouse click ...

Ok so in that matter than when you stop the VE learn there is a "apply" button or something like that? that saves it to your calibration? and so does VE learn ONLY learn the VE or other aspects of the calbration as well? and what calibration you think i should start with? LO3 or LO5? it is a LO5 engine but its still got the 305 tb

 

and WB 02? where can i get one and honestly how much does it help? one more question, what is WOT? and it (cant be learned?)

 

WB can be purchased fro dynamicefi
WOT is wide open throttle.
It helps a lot. Recommended. I did not use one first 2 years of tuning. a/F on dyno then was 12.0/1.

Learn is VE tables with NBo2. With WB it could be PE as well. the datalogs help you make corrections for other areas such as choke open loopA/F AE etc etc.
Learn created a new .bin that appears in documents. can be accessed from tunerpro or flash
I would use LO5.bin but L03 will work as well with corrrections. I had a 350 day one on EBL and used L03 as that was all that was avalable.
Did you read all the stickies at DIY-Prom free tune in TBI forum and Intro part 1 and part 2 at dynamicefi?

 

Damn wish I knew that before I made my order! Oh ok makes more sense. I plan on trying both and seeing how they go I mean heck I got all the stuff to flash both in easy so why not? yes I have read both intro to tuning on dynamic efi twice, and still going through everything here. Doing lots of home work. Just lots of new words and abbrevations

 

If you order the EBL, make your life easier and get the USB cable they provide. You'll save money in the end. I thought I was going to outsmart them with my 3$ cable. The joke was on me with 10 trips to Futureshop and RadioShack. I ended up having to buy a cable online that ended up costing me more money and waiting two more weeks before I could drive the vehicle. The chipset of the adapter is key and is only available in a handful of quality cables. Even 70$ cables I tested were using the cheap chipsets.

Save grief, gas, time and money. Get the USB cable from them.

I've been tuning with the NB O2. I'm an EFI noob/tard. The WB is in the mail and I'm hoping to get better results with that since it seems to cover a wider range with more accuracy.

I did the soldering of the EBL to my own ECM, it wasn't too bad given my usual bad luck with mechanical things. If you don't have the soldering tools, ordering the complete one can be cost efficient.

Looking back, this EFI thing was not cheap. Start with the Howell, 1500$ as I thought this was going to be the last thing I'll ever need. Then my 360 dies, I build a 401 for which I stopped counting the money that I poured into that a long time ago, or I'd have a economic mental breakdown. The Howell would need new chips in the mail and all that.. Screw that burning chips crap, I chose independence with the EBL and that will be in the 600$ in the end. Although well worth it.

The best aftermarket service I've ever witnessed in my opinion. Where most aftermarket products patch you in China to a mister Bill Wong if you can get anybody at all, and you're lucky if you don't get the middle finger after they read their script.

Oh, and did I mention all this was for a jeep... yea, so everything else is falling apart and needs constant maintenance... What a great rewarding hobby I picked!! But given the bad shape of the roads year round and the amount of snow we get around here... A camaro or corvette isn't very practical. Ask my Honda Fit about it.

At least the EBL rocks. (I have no affiliation)
