misfire cylinder detection


Recommended Posts

IS there a way to determine which cylinder is misfiring using the #350z G4+ ?

Also, i am getting conflicting value for the dead time of the Denso 560cc ( blue) GTR injectors. Car seem easier to tune with 0.890ms@14V. But I would guess they are not linear flowing and I will need to get the pw adder value too.

Thank you.

You could have a look at the knock sensor signal for each cylinder.
When an engine is misfiring, that cylinders background noise level on the knock screen can be lower. (Depending on the engine and knock sensor fitted I guess)
Also the engine rpm signal can look rough.

There's no monitoring of the coilpack return signals though.
