hey .. i have a 91 convetible camaro with a 305 tpi that i have just rebuilt and put on new summit racing vortec heads, edelbrock's vortec to tpi intake manifold, edelbrock headers, flowmaster cat back, and a lunati cam (or another similar, havent decided yet, but its around 213/219 @ .50)

some have told me the car might not even start when i put it back together in a couple days and other say itll run fine but will need tuning

so ive decided to do some reading up and learning to tune and so far ive seen two options

1) buy a programer, aldl cable, and get the programs for datalogging and burning .bin files

or

2) i found this EBL flash thing that replaces part of the board and you can datalog and flash the chip without taking the chip out .. the "whats up" display program looks bada$$ too ..



im not too convinced on the first option .. but i was wondering would the ebl flash work with my tpi 305 .. i couldnt find anything about it on the website it just says 90 - 92 camaros, firebirds, etc ..

i have a z28 which is tpi .. but i know that regular camaros are tbi

but it says the ebl flash thing works with a map sensor ..

any advice would be helpfull


thanks ..

 

If you look on the site, he has a list of plug-compatible ( or within a pin or two ) ECM numbers. EBL-Flash can plug-n-play replace all of those.
If yours isn't there, the best thing you can do is e-mail him directly.
He will answer, and is one of the most straight-forward guys I've ever met.
If memory serves, it can run your car in batch mode pretty much without changes, but rely on what Bob tells you, not me.

 

The EBL Flash uses a different ECM then your stock '91 ECM. To use an EBL Flash setup your current ECM harness connectors will require re-pinning, along with the addition of a VSS buffer and knock sensor module.

It is a bit of work, but it all depends upon what one is looking for. The MAF TPI engines are easier to swap over to the EBL Flash. As they already have the VSS buffer and ESC module. And it is only a couple of pins to move.

EBL is embedded Lockers and is/was originally started life more on the TBI side of things, but can now be used on port injection as well.

see here, especially the last two pages:

https://www.thirdgen.org/forums/diy-...-ultimate.html

your combination is mild enough that it should start and idle and be reasonably drivable on a stock 305 tune, however it will in no way be "ideal".

My opinion would be to work with the stock setup (get a programmer and such as in your option #1) as it is likely the simplest way to "get started" and get your feet wet. The TPI '730 platform you have is very well understood and very well documented here, which is helpful when you're still learning.

When/If you do decide to go to EBL later, the knowledge and experience you gain from the stock setup will be very helpful.

 

bob,

i have a map sensor based tpi which has a vss speed buffer (it has cruise control) .. and i have a knock sensor

what would be required to "re pin" the computer .. i can snip all the wires and connect them up in a different way if required ..

just got the block back a couple hours ago from the machine shop ..

so yall recomend burning chips than doing ebl flash?


im pretty handy with computers and thought the ebl would be pretty cool to show off and it looks easy compared to pulling / re installing chips while trying to program ..



91l98z28

i just got the block back today and all those parts (heads, headers, intake, cam,etc) are sitting in the garage and im gonna start assembling tommorow ..

i bought this car for $1500 .. well i bought a bagged pickup from a friend and traded for the camaro .. .. and ive dumped $3000 so far into the motor

im just trying to figure out the best way to tune it .. looked like the ebl flash was a pretty convenient package .. especially for $350 dollars or so

ive seen something about emulators .. do those do a similar thing or is it best to just put in one of the zin things and burn chips with a programmer ..

 

Re-pinning isn't difficult. Merely extracting a couple pins from where they are in the connector, and re-inserting them where they need to be. There's a post or a sticky somewhere on the sight with a photo, just can't remember where....

Some recommend a burner and such, not all. Usually it's best to get your feet wet on a bone stock system, but isn't essential as long as you understand that there will be some things you haven't already learned that will come into play.

Yes, EBL-Flash *is* easy, as far as programming, logging, etc. and has other advantages as well in the code, options, etc. that don't exist in the stock system, but it is not what you have stock. It's not easier at all as far as knowing what to change, and why, but it's not more difficult either. The support is better.
In *my* opinion, it's much better than a stock ECM, and underpriced, but that's me.

 

well if i can use the ebl flash i would love to buy it and use it ..

im gonna get the car running first and if its rough than im gonna get it straight away .. if not im gonna wait a couple weeks and get some money built up to get the ebl flash, cheap ebay laptop, etc..

im only 17 and borrowed $3000 to rebuild this motor .. well more of a build than rebuild .. i didnt want to change to a 350 b/c i have emmisions and i like my gas mileage of the 305 .. plus its a convertible and i dont want to "over power" it .. if i had a penny for every time someone has told me "just throw in a 350" i could of bought a corvette by now .. haha ..


bob .. how hard would it be, if possible at all, to use it with my tpi ..

and am i right about my car has a speed buffer b/c i have cruise controll .. it has a brand new vss and theres two wires coming out of the connector ..

and i have a knock sensor ..

someone said its a 730' ecm .. i guess thats the last 3 #'s of the big ecm number ..

thanks for yalls help ..

 

You are correct about it being a '730 ECM (1227730 for the whole number, which is the service number GM used back then. There are 2 newer service numbers that may also be found/used. Same ECM, different number).

That ECM has the VSS buffer built into it. When going to the EBL Flash setup an external VSS buffer is required. GM installed these is a bunch of cars & vans. So are easy to obtain.

That ECM has the knock filter built onto the MEMCAL. When using the EBL Flash setup the knock filter is an external unit. A small plastic box. Again, GM used these on a ton of cars & trucks. So obtaining one is easy. A side benefit to an external moduile is that they can easily be changed. There are a couple dozen different ones that respond to the sensor signals differently.

For some engines others are better then the stock factory one. Can get ones from trucks to turbo setups.

As for re-pinning, the '730 ECM uses 3 connectors. Two will be kept and re-pinned to match the EBL Flash ECM. If you go with an EBL Flash order the Port Mod for 8 cylinders. That will have the injectors firing at the proper rate.

Note that the '730 is a decent ECM, and the $8D mask is also decent. The real difference is in the available tuning tools. There is also SAUJP available for the '730.

thanks a bunch ..

so if i bought a EBL flash in the future i would have to get an external speed buffer, and knock sensor module

there is a "pull apart" yard near by with a bunch of cars so would it be easy to just grab them out of one or would i need new ones ..

....................................................................................

im starting to assemble the motor today and im hoping to "try" and start it around thursday at the latest .. lol .. add two weeks and 4 months to that ..
always seems to take longer than expected ..

neways .. if the motor runs "allright" for now .. then ill just run it till i get the money .. if it barely runs or starts acting up im gonna have to do something ..

in my oppinion i'd rather buy your EBL Flash and wire it up to work and learn to tune the car ... compared to paying someone $380 to burn me a chip when the damn chip only costs $2


what is SAUJP?


Adrian

 

Used ones are fine. They are rarely bad. Actually, for VSS buffers and ESC modules, I've yet to get a bad one. The only piece I've had 'iffy' from the yard are CTS units. Sometimes they seep a little and the connector corrodes.

SAUJP is a modified version of the $8D code. It is based on the AUJP calibration. Some folks got together and modified the code to enhance it.

RBob.

 

aight cool .. so you thing the ebl flash should work just fine .. and if i got it could you tell me what i would need to do to hook it up ..

i got the motor half way put together today .. hoping to fire it up thursday .. assuming i get it finished tuesday, install wednesday, and touchups thursday (dead battery, lost bolt, etc .. lol) ..


ill see how the car runs/drives and let you know if im gonna get it straight away b/c if the car runs fine im gonna wait a little till i get some money ...

where would i get the SAUJP code?

thanks again

Search ThirdGen for AUJP V4
It'll return quite a bit.

Methinks the best thing you can do, is search ThirdGen for the Super AUJP, and study that, EBL and study that, and the related links that will come up.
EBL is a tool. It's a good tool, and I do recommend it highly, *if* it is the right tool for you. It's a great tool for me, but that's not a reason for you to buy anything.
There's a big difference between doing something quickly, and doing something in a hurry.
Don't get in a hurry ! That will hurt you in the not so long run. It's easy to accidentally do serious damage in a hurry, with any tool.

 

yea .. i agree about the hurry thing .. im building the motor right now and i love to take my time and make sure everything is perfect .. plus its gonna look sweet with everything cleaned and painted .. and i polished the plenum just for the heck of it (i'd recomend doing it)

alot of people have told me the cam im putting in should work fine for now .. so i might wait and buy a "custom made chip" or if im feeling up to it either use a programmer and eeprom chips or buy the ebl flash ..
