I am trying to get the Map sensor to show more than 105 kpa in my logs , if I change the properties of the Map sensor to 220 kpa max , it maxes out at 105 kpa , and when I insert the 2 bar map PID , it doesn't even work . Do I need to tell the PCM where to get the 2 bar map signal from ? I have the GM plug and play 2 bar map . Any help is greatly appreciated as always .
