Couple of Quick Questions

[slarsen47]

What is the conventional wisdom on selecting the HPtuner stoich value in areas where all we have is gas with about 10 percent ethanol?

14.2 or 14.7 ??

I have read discussions of GM two bar map sensor offsets, without there ever being a conclusion or explanation of when one or the other is used.

10.33 or 8.33 ?? Is it dependent on the altitude (barometric pressure) of your location?

I use 14.2 but I also run a little leaner on PE to compensate. All comes out in the wash with a wideband

8.33 offset works for my altitude and barometric pressure around 91 kpa.
