The car is supercharged and i'm wanting to use the OEM Tmap sensor for boost pressure in psi.

what formulas are being using for pressure?
right now i'm getting voltages ranging from 0.4 to 3.6 Volts

Hi:

We have no way of knowing the calibration curve of your OEM sensor. Perhaps the sensor manufacturer has info, or maybe you can somehow obtain voltages at a few known pressures??

Sorry if that is not much help...
