    EC Tune Histogram Question

    Hello Sir,

    Quick question. On one of your histograms for AFR Error that you have posted, you have labeled it as AFR Error Closed Loop. Just to make sure I have not missed something, would it matter if I am in open loop or closed loop in using this histogram?

    Please excuse my ignorance,

    Thank you in advance, I appreciate all your input into this forum!

    Basically I set up that histogram to ignore any AFR error when the commanded AFR is greater than 14.6 (most all calibrations are 14.62-14.68 in closed loop). So when you do have a non-closed loop Commanded AFR value (Eg 13.0) the histogram starts recording that data. Otherwise you get closed loop data mixed in with non-closed loop data.
