Would like to share the old style GM 3 bar sensor that my autometer gauge is using.
Take the input from that sensor and put it into my HPT pro.
can't find the formula to use.
My car is running off a 1 bar sensor as the AIC takes care of boost fueling.
I don't know the voltage scale of the GM 3 bar sensor either...
Don't care if I can't log VAC.
