Here is what happens
I plug in the boost sensor and the PFC just shows 4 black lines ( ---- ) for the boost reading, and the sensor shows 0.03 volts. If I unplug it I get a +1. somthing bar, and like 4.81 volts.

Did all the obious checks, looked at the wires, tested them, checked the hose going into the sensor, and I also tried another sensor with the same result.

I am guessing that maybe the PFC was setup for a GM 3bar sensor by the last owner since I bought it used. I don't have a datalogit yet, is there anyway to know if the car was set for a 3 bar with only the commander?

Anyone have any ideas at all?

thanks

Yes, from the commander you can check it from the PIMS screen. Scale should be 35086 and 3947 for option 1.

 

in the commander there is no PIMS screen, there is a PIM screen but all you can do is basic fuel correction for RMP and PIM volt. There is just a list of RPM / volts and then a 100% next to them. You must have to get the Datalogit to change the settings back to 35086, 3947. What do these # represent and do you know where they are entered in ?
