However, I do not get correct readings if I choose 2.5 or 3 bar sensor. My Autometer gauge shows 8psi. If I choose 3 bar sensor setting, I get 17psi, if I choose 2.5 bar - I get 12psi. This suggests my sensor is 2 bar, which is consistent with the reply I've got from Autometer tech support. Unfortunately, my hybrid logger does not have 2 bar setting. I've contacted Chris already about this. I hope he'll be able to help me out.

Thanks

I went back and checked my earlier math. With engine off you were reporting 2.2V which is approximately 112 ADC counts.

2.5 BAR
BAR = (ADC * 0.0098039) +.1
PSI = (ADC * 0.142193511) - 13.0534

2.0 BAR
BAR = (ADC * 0.0078431) +.1
PSI = (ADC * 0.113755059) - 13.0534

2.5 bar sensor would put you about 5700' below sea level and the 2 bar would put you about 500' above sea level. So either your car was in a mile deep mine or you are at ~500' elevation (or you live closer to sea level and the weather was really awful!)
