    2 Bar MAP SD

    When we decide to go 2 Bar Map which sensor should we be running and what should be done? Like do I have to dial in the map sensor or should it be a plug and play? They have been telling me to run MAP Sensor#EC1794... Is this correct?

    Aside from the obvious OS upgrade and SD tuning basics, there are a few other things to do. After the OS upgrade, the VE table will need attention as all the values will be wrong, and offsets for the 2 bar map will have to be filled in properly. The values for the offsets are in here some where, a quick search should turn them up. I'm on the Rgv truck and body sites under the same screen name as here. Mario G
