Help for a new guy please. I have a '00 vette with shorties, CAI and cat back. I'm using a Vinci tuner and a Proscan logger.
I started with the standard HiPerf Vinci tune and the logger shows my fuel trims are about where they should be. Pretty much zero at cruise and pretty even above and below other times.
My problem is the timing. At cruise and steady throttle, it's showing way too much advance, like 36-7-8*
The Vinci let me pull 10% which brought it down a bit but it's still way off(I think). During accelleration and at idle it Runs anywhere from 0 to 36*.
The car pulls hard and smokes the tires shifting to second but the numbers are way off here. Any ideas?

What makes you thing that is too much timing?? The stock timing table calls for up to 40* of timing under certain airflow such as cruise.. At WOT you should be no more advanced than 28*.

I've done a lot of searching and reading the last two days and all anyone ever mentions is 26-28* of advance. No one ever mentions cruise numbers. Not that I've found anyway.
Is there anywhere I can see a graph of this table? Believe me, I have searched high and low and cant find it.
