Knock during any chg in TPS! Sensor? ZF6 single mass FW noise? ESC module?
My ECM is detecting major knock whenever I blip the throttle under any condition - even no load!!! I haven't upgraded the ESC module because everyone lists WOT knock symptoms when they consider the upgrade. It's the not the ECM because I swapped DFI into the car, and the problem still remains. It knocks with only 18 DEG total advance in neutral so it can't be the advance map. Noise from my ZF6 due to the single mass flywheel? Bad knock sensor? Any ideas?

Check for anything banging around-exhaust clearance too tight etc. Just how noisy is the clutch? The ones I've heard only rattle at idle. BTW- You didn't install a cam gear drive? That would do it too. Good luck- the majority is usually somthin' simple.
