i will check and see if the chip is seated properly and if not then its probably done for huh?

If you want the EPROM checked out and/or reburned, send it to me and I'll take care of you free of charge.

Send me an e-mail at scott231@gnttype.org with the subject line of Chip Repair if you want this assistance.

So weither you unplug the orage wire or not, the ECM still has to "re-learn". About how long does it take for it to re-learn? I mean would it better my ET's if after I put my racechip in, I drove around for a half hour or so to let it learn?

That is correct. If the EPROM is bad, then the ECM ignores all inputs from the sensors. But, in order to run the motor, the ECM needs values from the input sensors. Since that is not possible with a bad EPROM, the ECM uses default values from the Calpack chip (the little one right next to the ERPOM.


Good point. If the SES flashing goes away with an ECM swap, the first ECM is bad. If the SES continues to flash, it is a bad EPROM.

Scott thanx SOO much for the info & your help (you other guys too)

my car is at a shop (TR Specifc) right now i asked him to look into what chip is currently in there and he is also fixing some other little problems while doing my rear mail seal
