520hp@26lbsRX-7

I was driving last friday night when all of a sudden I look down at the Power Fc controller and its turning back on like i shut my car off then it gose back to normal reading the boost and rpms. The next day I see that it is doing the same thing but after awhile of driving the car i look down and the controler and it is off and will not come back on. Get home pull all of the fuses out none blown. What do you think happend?

if you feel confident, take apart the controller. Maybe something internally happened.

Did you check all the connections?

I've had a random connector slightly loose (not even fully disconnected) to where it disengaged the boost sensor and caused the car to stall.

I've had a problem with the Commander plug working it's way loose where it plugs into the PowerFC. I used some electrical tape to help hold it in better.

yeah, the commander stops working, but the car runs fine..is that what you are saying? Just unplug the commander and plug it back in, making sure it nice and tight, the tape idea would be a nice insurance that it doesn't work its way free.
