    AFR Error not working and I don't know why

    Please take a peak at the screen shots. I've set this up a couple times now using the tutoring section here and I still have no luck. It only populates the one field.

    What am I doing wrong?

    Thanks.

    You have the wrong values in the KPA and RPM field on that spark advanced graph. Just look at that screen shot.

    The MAP kpa goes 400,800,1200 etc etc etc and it should be 15, 20, 25, 30, 35 etc etc.

    Same with the AFR error graph, look at your numbers in the axis, they are all wrong for what a MAP reads.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
