Message As far as I understand this concept, the OEMs use higher tooth counts for diagnostic reasons such as misfire detection and identification of which cylinder misfired. This is done by comparing the time between trigger events and if an RPM deceleration blip occurs in a normally steady or accelerating RPM trend, then a misfire is proclaimed. I can easily be wrong, but other than misfire detection, I don't see a benefit to more trigger points.

Do any of the aftermarket Z32 ECUs feature misfire detection?
