Hypertech chip and timing ??

withamc · 06-17-2001, 10:44 PM

OK. I've got the engine, trans and rear-end swapped from my '86 convertible to the '93 GT. It didn't quite have the "Light-em-up-ability" of the convertible, plus I was getting some pinging on the top end. Timing was set to 16 just like it was on the '86. So I went to swap the computer and I find out the '93 already has an A3M with Hypertech Power Module on it. The '86 has the A3M1. I know most of you don't like the generic chips, but...
1) Since I already have it should I use the Hypertech? If I do, should I set the base timing back to 10?
2) Is there any difference between the A3M and the A3M1?
3) Would an A9L make a big difference?

Chuck the chip.

The power you are getting it is because it bumps your timing internally. Yes, you'll have to drop your timing back down to 10* initial if you put the chip in.

would you have to put the timing back to 10 if you put a chip in with 14 timing, what will happen if your timing is @ 14 when you put the chip in?

I had a custom chip. Your supposed to reset the timing to 10. Mine didnt do crap for my car

Whatever your timing is set at..the chip will advance it another 2-4 degrees.
so if your on 14* then it's like running 16*-18* timing.

I pulled the computer and put in my other one, advanced the timing back to 16. Much better!
