Hi,
I noticed that the ZR1 map sensor is listed as a 2.5 bar sensor, but if you look at the scaling in a stock ZR1 tune file, it is scaled at 312.500.
I have used it in other applications, and found that my KPA is off (100KPA might read 135 +-) which would coincide with the sensor being a 2.5 bar, yet why is it scaled by GM at 312.500 when an older style 3 bar sensor would be scaled at 282?
Anyone come across this?
Thanks for your time.
