I have a 2006 chrysler 300 which has been stroked to a 7.0L, and i have now added a supercharger from a hellcat. My question is. Im trying to rescale the ecu for the map sensors for that of the hellcat, which i thought i had correct. But i am still getting a code of p0129 or low barometric pressure reading. So i must have done something wrong. Any help would be great
Since you're working with an OEM sensor, have you tried copying the stock data from the vehicle the sensor is native to?
If yes, perhaps confirm it's scaled in the same manner, same units as your ECU.
I'd also confirm the sensor min and max voltages for errors as they may be different too.
