PicoScope 7 Automotive
Available for Windows, Mac, and Linux, the next evolution of our diagnostic scope software is now available.

Grass hopper.As misfire detection is done by the ecu by monitoring the fluctuations of the engine speed sensor, is it possible to monitor this signal varation yourself using a picoscope?
You might find this case interesting:heady2010 wrote:Ok thanks for the information. My thinking behind this was that I have heard of cases where the crank bearings have worn (without creating excessive knock) causing a fluctuation in the engine speed signal and then making the ecu think there is a misfire, I'm thinking this wouldn't show up on an ignition wave form or a in cylinder preasure transducer?
