    Default Limits for Cos 5

    Hi
    I am running cos 5 (2002) (156) on an ls3 engine with e-force supercharger. After the supercharger install the timing and the fueling are acting strange. The timing is dropping dramatically in boost and the ve table is looking strange.
    I wonder if I am maxing out some tables (hitting some of the limits in the os)
    The setup is stock 6.2 L ls3. Stock e-force supercharger kit for Camaro. 411 pcm. Mafless tun.
    4l60e trans.

    What is the limits for this os ( PCM) that i can hit with this setup?

    You would really need to look at the particular PIDs you believe are "strange" and potentially oing out of range. By looking at the PID units (i.e. grams/s, grams/cyl etc) you'll be able to see which table (i.e. spark, airflow) that you're looking at. The PCM limits are going to simply be the highest value on the specific table axis. If the PCM is operating off of the axis (in terms of the PID values) you will always get the value from the last cell.
