Knock Signal Correction Mode On Safc2

[fishy]

just installed a safc2 into my car (er34)

pretty much stuck on the knock correction mode..

check threads regarding knock and setting up safc2 but none of them tell me which reading i should use.

when i rev my car at 3.5k it gives a knock of 34 and 70(can't get a stable reading)

so my question is, which reading should i use? the low one or the high one? or is something wrong with my car?

go into the knock correction setup menu. from memory it wants you to rev the car up at 1000rpm and 3500rpm?? have the 1000rpm highlighted, then you rev the car up to 1000rpm and hold it there. then press the little center/enter button. then highlight the 3500rpm and do the same thing there.

and to answer your question, you would want the higher number. if your car is getting a reading of 70 at normal engine operation then you would want it to ignore anything up to that value. if you set it to the lower value you will get incorrect, high knock values.

thanks for the info qek32. i was thinking that also. looks kinda abnormal as the higher i rev it the more jumpy the figures went. will configure it tomorrow.

thats not abnormal. the more you rev and engine the more noise it makes. and a knock sensor is basically a mircophone.
