Edge Error Code
pulled this diagnostic code from the Edge "P-0642", I have tried to find what it represents but no luck.
I have an 05 FX4 5.4L, the code was on my programmer, no check engine light etc....., I found it playing around with the unit itself.

P0642 is a generic OBDII code that says your knock control is defective in the PCM. Since you have a tuner I would say that its in the tuner and a reboot of the EDGE might take care of it, if not contact EDGE tech support.
