unless they removed the knock filter as well, then i would say it will be functional again.

generally, what i have found is that the C3 ECMs used a 100K sensor, the P4 with an external knock filter(7165) i think are also 100K, P4 are all 4K, P6/66 are all 4K(possible exception for the dual knock sensor applications?), then OBD2 went back to 100K.

IF, emphasis, i'm remembering correctly.



i would take a look at your knock attack/restore tables as well, they might have thrown those way out of whack too.

i don't think this is the first time a Harris complaint has come across the radar either.
