    VCM 2 Bar change.

    While looking through one of my tunes I saw this. I looked in several other of my tunes, including the OEM, and had the display. What is this about? I am not aware of any change. Do I need to do something to clear this up?

    That is a custom OS that can be applied if running a 2bar MAP sensor. It will apply more bars to the MAP readings. Stock 1bar is up to 105kpa in my ECM and when I installed the 2bar enhancement it is now 210kpa. You do not need to change anything unless you want to run a higher MAP.
