    I have all those and also selected Volumetric Efficiency for v8 just in case.
    My biggest problem with this system is figuring out what pids are needed for each map . Is there some way to find that ? A tutorial on that?

    For COS5 it tells you to ground PIN 56 on the RED Connector of the RED/BLUE ECU. What is the PIN on the GREEN/BLUE ECU ? Is it the same ? PIN 56 ?

    COS5 is not available on 1MB PCMs that use green/blue connectors, only 512kb ones that use red/blue.
