Had my new diagnostic toy a while now,a 3223 certainly a very nice piece of kit.

I tried the pico diagnostics cylinder balance with mixed results,still a work in progress I think.

This led me to using the math channel for misfire detection.I have played with this feature using the equation (A,36) and (A.60),the car is a 2001 renault scenic 1.6 16 valve petrol.My results seem different to what I was expecting.

Ive attached an RPM capture from the car,can somebody apply the math channel and maybe add some data, comments etc

cheers
