ok, i found some ECM's on ebay starting at a buck... just wanted to know what numbers i need for a 84 TA... go look at this please!!! http://cgi.ebay.com/ebaymotors/aw-cg...094162&r=0&t=0 i want to buy it so i can send it out to someone to reprogram it... please help


1227169 1226455 1225950 1225500 are the numbers of the ECM's he has

 

84 TA
CCC, is it not?.
There isn't the info available for reprogramming it anyway.

Actually no need to,

Just get the ZZZ retrofit instructions and use the chip/ecm numbers in it.

Then get Coug Roes Quuadrajet Book, and start reading things REAL close.

 

no offence Grumpy, but can someone second that??

 

where can i find the ZZZ retrofit instructions and Coug Roes Quuadrajet Book????

 

Okay, I second what Bruce says. Many of the earlier ECMs have very limited information available. They had a very short Service Life and what they controlled was quite limited. By the time "hot rodders" got into hacking ECMs, those "old timers" were already forgotten about.

Today, all the "new activity" is with the newer ECMs like the 8051s used on 94/95 LT1s plus a bunch of guys trying to hack the newer OBDII systems. The only reason there is still activity on the SD7730 and MAF 165s is because a number of us F-body and Vette guys that have these in our cars that are interested in it. GM produce a fair number of these ECMs for these cars and there is enough of us guys that were interested and dedicated enough to make companies like TunerCat to produce the "tools" to allow us to modify the BINs.

This is part of the reason there isn't much for info on the BINs for the 302 ECM used on late 80s V6 F-body cars. The 302 wasn't used on a lot of different cars (not like the 7730 SD), and there just isn't enough 2.8 V6 F-body users that are interested in modifying their eproms to make companies like TunerCat devote much "R&R" on the 302 ECM's BIN. They (TunerCat etc) would rather devote their R&R to the newer ECMs like the 8051 and OBDII systems where there is a larger market for the product.

 

And, before Bruce says it, a lot of people just want to wait until someone else does all the work (hacking) and then just ripoff the efforts of others by creating a company and product to gouge all the rest. Very few are sharing the information like they use to - everyone wants to make a buck, yet not do the work.

 

so waht does that zzz thing do then?
