Im pretty sure that my knock sensors do not work becuase I can't remeber the last time ive seen knock but I can definately hear it.
Anyway with my 02 switchpoints lowered I think its causing it to lean out when the TC is locked at high loads in low rpms. Does anybody else notice this?
I noticed this pinging a long time ago but since it never came up on the scanner as knock retard I never really did anything about it.
I just put my o2 switchpoints back to stock just to verify that it is pinging becuase its running leaner at lighter loads.
But what I don't is when the tc is locked under load I don't think its in the loads where the engine is leaned out.
I think its a wierd situation becuase the CL modes are referenced by aiflow from the map.
So I would guess airflow would be very low at the low rpms that the tc is locked?
This mostly happens when im hitting hills but ive also heard stock cars do this and I even read in the manuel one time not to worry if your hear slight pining when going up a hill. I also have headers which I guess might amplify the pinging but I wouldnt think so.
