    Thanks

    2004 Mazda Tribute V6 Misfire

    Hi Not sure what to make off the fire line slopping in the positive territory and going negative. does that mean the KV needed to fire the plug changes polarity once the spark plug gap gets ionized? but why? I think this car is the same as Ford Escape. The data file is captured with a the power prob...

    Distributerless Power & Waste Split Screen Scope

    Hi Are there scopes that display the secondary ignition pattern (with waste spark) which provide a split screen showing the power spark in one and the waste spark in another "under each other" at the same vertical line for easy of reading? I have pico scope model 4423 running software version 6.14.2...

    No pico for Dummies yet, but meanwhile it is well worth it to take a look here http://www.autonerdz.com/cgi/yabb2/YaBB ... rd=picopub

    Re: Graphing PWM and Duty Cycle

    Pico can graph frequency, it can measure and post "in a text box" the Duty Cycle (under Measurements). Sure it is not too far fetched to capture and graph streaming Duty Cycle, I am at lose as to why it "and PWM" have not be implemented yet. Other scopes "used in the automotive field" graph both.

    Graphing PWM and Duty Cycle

    Hello
    using 4000 hardware with 6.7.11.1
    Is there a video or written instructions on how to graph PWM and duty cycle "of say an injector"? if not, how can it be done?

    Thanks
