    Trying to troubleshot a random misfire by doing crank position relearn on MaxiPRO. Revved the engine 3 or 4 times and got no confirmation. Any ideas?

    I found that the prompts are incorrect for this procedure. The screen that explains how it is done is not where you do the procedure from press the button to go to the next screen to do the procedure and follow those prompts. It totally confused me the first time I used it as well.

    The prompts are incorrect, CKP variation procedure is to hold throttle at WOT until RPM fuel cut occurs...
