Putting in a different Chip...quick question.
Got my chip today and am getting ready to put her in....just wanted to double check this.
Is it ok to leave the battery connected.....? or should I disconnect the negative terminal...
My helms says....to disconnect....just curious....I would rather keep in connected if its ok...
Like keeping all my presets on the radio....and don't want the computer to have to relearn stuff either...
thanks
Jim

Rocky, I don't think you have to disconnect the battery. I recently had my car tuned, which required about 6 chip changes, and we didn't disconnect the battery between chips. I didn't have ANY problems and the car runs great!!!

You should disconnect the battery.
You wont like it if you fry a chip.

Pulling the ECM fuse should have the same effect - no power to the ECM. Better safe than sorry.
I am changing chips daily without disconnecting anything, no probs, but I have the adaptor that keeps the memcal in place, only the PROM chip comes out. YMMV.

I used to disconnect the battery because the manual says to, sets the aftermarket alarm off when I reconnect. But then Jim Jones at Traco Engr. who programmed the chip for my 86 said I didn't have to. So I haven't since, and haven't had any trouble. Did my 87 and 92 that way.

Yes, definitely disconnect negative side, unless you have a static strap and a good ground to clip onto. :yesnod: It's easy to disconnect and you'll save the chip! :D
