    FA Enrichment

    Hi guys
    Still new to this platform.
    Have a 5.7 eagle with a baby cam and 6.4 intake and injectors
    Car is a 1970s car with the Mopar crate PCM.
    I have set the fuelling to run 12ish AFR via inj pw.
    I raced the car on the weekend and in top gear its adding a big FA enrichment in the .03 range
    PE is set to .01 across the board so its getting .02 from somewhere.
    Cat overtemp is raised to 3000f so i presume thats basically disabled.

    Is it maybe a torque management adding fuel to it?

    What else can add PE to it?

    All the minmum thresholds seem to be set at 3002 deg f so shouldnt they never activate?

    Your "Target Cat Temp" and "Target Cat Temp Misfire" parameters are still set to values less than 3002*, they might be triggering COT. Also your "Target Exh Temp" table is not set to 3002.

    Set all temperature parameters to 3002, including your delta fields, then set your "FA Enrich Max" table to all zeroes. That should take care of any possible triggering of COT enrichment.

    Your target COT temp appears to be stock value.
