Which cylinder is the "knock window" setting?


Recommended Posts

I'm using Link G4x atom with toyota 4e-fte
The knock sensor is BOSCH

In the knock control settings, "windows start", "Windows Length", is this the setting of cylinder 1 ?

In my engine, I installed one knock sensor between cylinder 2 and cylinder 3.
I want to measure knock with cylinder 2 or cylinder 3.
Is it possible to set it?

If you have set the injection mode set to sequential and depending on trigger mode selected, the ECU has reference which cylinder is firing ignition. The knock window will be for each cylinder that is firing for each cycle.

Post a copy of your tune file (*.pclx).

Since your engine has a trigger capable of 720deg sync, the ecu always know which cylinder is firing - even with a distributor.  So It checks for knock in the knock window for each cylinder after the cylinder has just fired.  If it hears knock in the knock window for cyl 2 after cylinder 2 just fired then it knows that the knock came from cyl 2.  Placement of the sensor doesnt matter, it will hear knock from all cylinders.
