    Default Spark Map Question

    I was fooling around today with learning about the MAPs and trying a few out. I loaded up 2 that I wanted to see so that I can adjust spark to get rid of some KR in areas that I was seeing on Logs.
    Well in the Scan Tool Map of B5913/B5914 (High-Low Timing Table - Spark Retard (MAF) it had columns/rows of RPM vs. CYLAIR
    Under my PIDs, CYLAIR was not an option for my PCM. Can I just make a custom MAP and instead of using CYLAIR, use GM.DYNCYLAIR_DMA ? In my Tune tool under B5913 and B5914, thats what it has.

    Thx, Michel


    Oh and I also selected the MAP (ones that were already in the MAP Folder) for the same thing under Speed Density and it already had the DYNCYLAIR_DMA for its column/row vs RPM. I didnt get a chance to road test and see if it fills yet.

    Hover your cursor over the CYLAIR axis and you will see alternative pids you can use.
