Where are you located? If it's just a matter of reading the old chip, that's doable, but what will that buy you? Chips don't really "die". Sounds like you're just looking for a tuner?

mike,not really.my issue is if the ecm wont communicate then the issue becomes what was on that chip to begin with?obviously a stock one isn't gonna do right by this set up and i am not looking to invest a ton in this car.i bought it to sell.i got a stock 91 and a tuned port 68 firebird.wifey says too many toys

The chip is separate from the ECM and can be read. But you'll need a new ECM if it's bad anyway, just put the old chip in the new ECM and move on. Still trying to figure out why this is in the forsale/wanted section...

If you want me to try and read the chip, I can. I've seen a couple Moates adapters go bad. Otherwise I think you're in for a retune as no one will have an exact combo as yours to have a tune to copy.
