    With key on engine off, MAP sensor should read same as barometric pressure (100kPa at sea level).

    E38_0041.efi

    KPA is at 85 on start. Any tips on editing to 100? I see map subheading under "airflow."


    Updated tune.

    I'm not sure about your NBO2.

    Looking at your tune B2101 (under Engine Sensors -> Parameters) is set for 1-bar MAP sensor, is this what you have...?

    Yes, disable cat protection.

    See your other thread: showthread.php?14279-Wiring-L92-with-O2-sensors

    12591290 is a 2-bar or 3-bar sensor, I don't know which one.

    Thanks!!!!!
    B2101 should be 128.125000 and B2103 should be -0.312500 if its the same as the ls3 which i would say it would be because i was getting similar reading to you with your stock settings. It seems like they are a 1.5 bar sensor? not sure strange.

    Nathans1987, Thanks man.

    In this version, I turned off the CAT protection.
    Updated MAP to the above and have MAP at 102 before start so much closer. Still a little high though.
    Joe Car, Geoff pulled the injector flow rates from a 2010 Camaro LS3, with, I hope the same MAP I have.

    Anyways, seems much smoother now, less eye tearing from the gas smell.

    I will work on reintalling LC-1 today.

    Thanks very much guys. Here is new log with your changes.
