PIM to PSI Conversion

Power FC tuning IS overwhelming. It’s as user friendly as it can be, but engine tuning is not a user friendly process. Here is one of the many calcuations and coversions you will come across.

This pertains to the PIM values that PowerFC ominously hides your Boost Pressure as. They actually correlate to PSI.

PSI=(PIM*0.001422)-14.7 approx
