Wondering if the ecm is bad at the pin or somewhere else internally? Or if the adx file on this site needs edited to work? I have searched around and it seems there can be issues connecting to these computers.
Car is a 93 fbody lt1. Has mild cam and full exhaust so it needs a tune. It did have a hypertech stage 2 chip in it and did seem to run ok but rich at cold start. I was able to burn a chip using a slightly modified bin from the $DA3 thread here, i believe a BDZL bin. Car runs on it so ecm seems fine but i cannot get the aldl to work to log using tunerpro rt and moates cable.
first off this isnt my first time, i have tuned many tpi cars, some tbi trucks and other 94-95 lt1’s as well as 96-97’s using jet dst. My cable connects fine to other cars. I have a spare tpi 730 ecm here i hooked to battery and connected fine to verify my cable works last night.
we tested the aldl port wiring all way to ecm connector and it is fine. I pulled ecm and put it on the bench with battery connected to the power and ground pins and pinned my cable to the aldl stream pin. Tried everything i could and nothing connects. I let it try the $da3 adx for 5 min and never gets thru. I tried tunerpro version 4 with a $da2 ads and nothing.
what else can i do? Thanks
