At first, my problem is what u stated - knocking during the day and night. So i had TXS take out some of the timing.
It was weird though because on the dyno, i was running 22.5 timing @ 5250-7500rpm and there was no knocking anywhere, and we thought we had a good tune. But when it hit the road, the knocking showed up straight away, so it is now down to 21.0 timing at the same rpm. At first we thought the problem was noise from my gearbox - i am running straight cut gears 1st to 4th - but then we put the headphones on the block and couldnt hear any major noise from the gearbox except for the obvious whine.
The headphones were not picking up any knock either just last week, which was weird?!? But i have been driving on the weekend and getting the knock regularly...
