Thread: HISTOGRAM question

    HISTOGRAM question

    When trying to log a histogram obviously you have to be logging the correct PIDS or said histogram won't even show up when you're logging. Where can I find what pids that need to be monitored for any certain histogram to work? I would assume I'm monitoring all the pids to do it in this case, can't be that complex hahaha

    FWIW I'm trying to find VE - AFR error on an 04 cts-v. What pids do I need to be logging? If that histogram won't work with that car, what do I need to do to build one that will?

    Thanks

    rpm & map for the two axes, commanded afr & actual afr for the afr error pid to work properly.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    I'm not logging commanded AFR, and I would think i should know that......

    Thank you

    Is there a way to know on any other histograms what I might be missing in the event I make this mistake again? Because I know I will hahahaha

    its the axis labels & whatever pid you are trying to plot.
