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
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
thanks
Mike
