Howdy,
I was scanning my '99 z28 (LS1 with mild boltons) looking for a different problem and added the Oil Pressure PID to the table... To my surprise it read in at ~100psi. Guage on the dash showed ~40psi.
What gives? AFAIK, I've not purposely changed any math conversion or whatever in HPTuners...
I can provide the scan file if needed.
Thanks!
Mark
