    Default LS1B Custom OS

    Where can I see what OS are available. I have an 04 C5 I am working on and would like to know what my options are. I am thinking I am going to need to convert the car to Alpha N and was curious if this was available for the LS1B.
    Thanks
    Justin

    It's not shown in that tutorial but COS 5 has a TPS VE table (A0007), its not Alpa N as in MAP and TPS , table A0007 is RPM and TPS.
    There are also options from A0003 to A0006 to control when this table is used or not.
    Hope this helps

    alpha-N is TPS (alpha) vs rpm (N).

    COS5 has an alpha-N VE table (TPS VE table).

    Read thru this COS5 summary: COS5.txt
