I am getting ready to go through the autotune process with my now NA Vette. The problem that I see is that I can not create a MAP reading any higher than about 78-80 kPa due to the high altitude here. Should I just to a linear fill for the values between 80 kPa and 105 kPa?

What I do is tune to the 85kpa cell copy those values to the 105kpa cells add 5 to 10% and then do a linear fill from the 85kpa cells.

This is so that when you go to sea level the mixtures richen up.
I have not yet tested to see what exact increase is needed.

I was hoping that you would respond. I knew that you are at high altitude and do alot of tuning.

What you suggest makes perfect sense to me. That is what I will do as well.
