Pulling My Hair Out! Someone Help Please!
Ok I used Craig Moates G2 adaptor ( for my '92 firebird LO3 with an 8746 ecm) now my car runs in limp mode( at lest I think because it starts and runs with no chip in it) I'm so pissed and i don't understand what is wrong because it wont ever give me error codes.

You have to put the memcal on the adapter because the knock circuit is contained in it.
The loss of the memcal will make it run in limp mode.
I forgot to put mine on when I first installed the G3 and had the same thing.
Pop it on there and things "Should" get better.

Um i don't think I have a memcal because I have a TBI system so limp mode is in the ecm itself. Thanks I'll try to use your help in some way though thanks

Well 2 things can be wrong; either the adaptor has bad solder joints or you didn't program the chip with the correct offset. Another reason might be your actual burning process, if you select the wrong chip it can damage the chip and won't verify. You CAN program the small bins into the at29c256 chips but the burning software needs to be setup or it won't work.
I'm sure somebody that's used his adaptor can give you some exact help with the offset, I don't have that adaptor, I have the earlier version that has a switch on it (8 calibrations stored).
