I just installed Quad commander and stealth 2 tonight. On Commander the boost is stuck at 46 psi and that was right when I turned the truck on. It showed 46 psi right away and I can't get it to delete itself. I rechecked the wire taps and all hookups seem fine. I tried to delete boost number on datalogging and can't get it to return to zero. Anyone know anything about commander?

Not to familar with it but unplug your ground wire or one of them to kill the juice and maybe memory. Then reconnect wire, it should come back on like just installed

you could see what kind of voltage you have on the wire you tapped. I would assume that the Commander just reads the voltage like the trucks ecm does, and if this is so then 46lbs of boost would reference around 4.6-5 volts, or so. SO, if you have 4+ volts, then you may have gotten the wrong wire tapped, and thus why the Commander is showing so much boost. Most map sensors with just the key on put out .5-1.5 volts, so if your not in that range start tracing down the signal wire (center of the three wires) from the map sensor and make sure thats what your tapping.

also, if you disconnected your wire tap for the boost, it should then go to 0,(in theory) if it does, then you know the problem is the wrong wire.

I figured it out this morning. I tapped wrong wire directions were not explained very well and put wrong wire on tap but now it works.
