    EQ ratio error histogram help

    I?m working on a turbo 08 Silverado E38 pcm with the 63.5 hard limit on the IFR. I did the double stoich half IFR method so now to dial in the VVE table I need to do it by EQ ratio error since AFR error won?t work due to the Double stoich. I?m having a hard time setting up the EQ ratio error histogram, I have an AEM wideband 30-4110 logging through the ac pressure switch since I don?t have pro how would I go about setting it up any help and information is highly appreciated, thank you!

    I have that part figured out the part I need help with is the math equation to give me EQ error % I already have the wideband configured into the scanner

    Again, a little searching goes a long way.

    Percent error is quite easy. True would be the commanded, observed would be what the wideband says.
