Message: My guess is that the programmers, SC/Hypertech, rewrite the tables in the PCM for both open and closed loop modes. The PCM would use the new values in the rewritten tables to make adjustments. i.e. stock table says 'x' amount of advance for 'abc' conditions, rewritten table says 'y' amount of advance for 'abc' conditions

Message: When I lived in Payson (5,000 ft and above) we advanced our timing to the max to get any power we could up there.
When we would drive to Phoenix we'd get pinging on occasion and pop the hood and bump the timing back a tad.
That was on distributor type engines with carbs of course :)
I never heard of the 1 degree per 1,000 ft before, but it could be fairly accurate.

Message: I ran 89 octane in tow mode pullling 5200lbs and had no pinging at all. Maybe it depends on what mods you have.

Message: Yup, depends on mods, altitude, grade, gearing, tire size...many things.
Lead, follow, or get out of the way
