Still having problems with code 22 knock sensor coming up... It only happens when the car is under no load, e.g. idling(when hot) and decelerating after a sprint or just slow 30-40 mph driving. Tends to happen once on a 25 mile journey. Never come on under load or I wouldn't still be driving it.

I know the MAFs are quite rubbish but rom raider logs looks like it works quite well. Does about 10g/s MAF read for idle sound about right?? It shows 288g/s at 3900rpm with 11 psi boost.

I'm getting really stuck now, as everything appears to be working correctly.

Half way through changing the plugs to see if they can tell me something. Bloody rain
