GM EPROM Project

These files are for Educational Purposes ONLY! I make no claim about their performance/operation/origin. Please don't blame me if you use something here and it doesn't work or breaks something.

This project started because I found out a buggy EPROM in my '85 TPI Z28 was causing a hesitation in 3rd-gear@3600rpm. I'm trying to collect/archive stock GM/FBody EPROM images so that people have access to the stock code if they suspect their EPROMs are causing them problems, or if you're swapping engines/ECMs in your GM/FBody.

If you have the means to copy your Stock EPROM , please email it to me to include it on the list below. If you have your stock EPROM out of the car (replaced with an aftermarket?) and can Snail-Mail it to me, I can read it and send it right back.

If you do send me an image, please include

I can currently modify the Parameters in the '85 - '89 TPI chips (Fan Temp, Spark Adv., TCC, Air/Fuel, Injectors, etc.) with the GMEPro   software, and 90-92 TPI systems using the   WinBin Eprom editor   and   My Current ECU file (for V0.11 of WinBin) for the 90-92 '730 TPI-MAP system

Local copies of Winbin Ver 0.11 and Ver 0.14

 Dan Townsend's ECU file collection for the 89 '165 TPI-MAF system   '89 image can be used in any '86-'89 TPI system with minimum chip changes
