Changed Knock Sensor - Now getting knock and high Knock Control on same tune
Posted: Mon May 18, 2020 2:02 pm
I had a knock sensor break in half. I replaced it with a new one and now the knock level is much higher in the same conditions as before.
Knock level was peaking at 15% during cruising before and 55% at WOT. With the new sensor it's now 25% when cruising and 75% at WOT.
Knock Control would stay at 54% before and is now going to 100%. It is now retarding timing and also registering knocks in all cyl. Never seen it register a knock with the old sensor.
Do the knock tables need to be adjusted when changing knock sensors? Seems like the new one is "more sensitive".
I put the "return to stock tune" back on and it also has the knock control go to 100%.
Some of these knocks are at low RPM and some are at high RPM.
Ill attach logs of the new sensor and old sensor.
