I see.
The voltage is between 13.5 and 14 depending in the electrical load (lights, defogger, fan...).
I'll probably tweak the region between 12.5 and 15 V

My version of LS1Edit can read only 97-98 programs.
Could you take a look at the differences beween the years? Let's say 98 - 02?
If the cam grind plays a rule on how GM programmed those values each year should be different. If they are the same it would be interesting to understand why F-bodies LS1 have different values than Corvettes.
