just had the rex out and for sum reason when your going up hill under load the warning heat light keeps coming on? also the knock level on my pfc seems to go up under load? dont think it did this before? could it be to do with disconecting the battery? hope its nothing serious?:3Confused
Does the heat light come on and stay on or does it just flash?
If it flashes three times it\'s the knock warning from the PFC.
If it flashes every 0.5sec it\'s a max injector duty warning from the PFC.
If it comes on and stays on it\'s a sensor failure as reported by the PFC (You\'ll need a commander to check - or pull the fault codes from the diagnostic port)
Don\'t worry too much about knock warnings - ASSUMING YOU HAVE BEEN MAPPED PROPERLY.
The knock sensor is just a microphone next to the block tuned to pick up the frequency of knock. Unfortunately, they tend to pick up everything else as well. Mine was set off by exhaust, dump valve, etc. Knock will tend to rise under load, but is only really an issue at WOT (wide open throttle).
Out of interest, what values are you seeing?

i think its ok, i went out again last night and it never did it again. It was mapped be pip about 4 weeks ago so it should be ok!:yes
