    Spark Air Mass Scaling E80

    2016 Cadillac ATS 2.0L

    I have ran into an issue with my Spark airmass, the stock axis is from 0.08-1.36. Can I add additional rows for above 1.36 or would I need to scale the tables in the mid-high range? I am seeing a airmass as high as 1.52, mostly in the middle of pulls. I am also seeing the highest average KR on my pulls showing up in that region and would like to adjust the spark to avoid that KR(avg of 2.5 @ 1.52g,2800 RPM

    If I scale the spark table, I also assume I need to do so for some of the other spark tables and also remap part of the fueling to compensate for the changes...Are my assumptions correct?

    Solution:

    Scaled the axis of the spark airmass

    Hello, how did this work out for you? Did you need to adjust all of the spark tables to match?
