So I tried it with the PSI conversions (8.948 psia/V and +0.435 psia offset) and still threw a P0068
. The strange thing is it corresponds with the stock sensor on stock scaling... I recorded the atmospheric reading with engine off and got 14.65 psia and then started it, let it idle for 2 minutes and got the idle reading of 4.93 psia.
I then flashed the same map with the stock mapping and got the same values. I did drive around and let the ECU do some learning before taking the new values down. Any ideas or is it just a characteristic of a sensor with less fine intervals causing the code?
