    fuel enrichment in closed loop? 2013 5.7 ANN possible

    Under light accel I miss power.
    Is there a way to give light fuel enrichment in closed loop with ANN ?

    No.

    Unless you are running leaner than stoich, fuel is not your problem with power.
    If in doubt, multiply everything by 1.1.

    You might have some luck with the ?transient? fuel settings but the CL feedback on these are pretty quick to respond

    in my opinion transient is only at warm up.
    but I dont find the trigger, when warm up is finished.

    I believe you must be talking about "Burn Fraction Inverse" table which only does enrichment immediately after start up.
    There are lots of other parameters for transient fuel for both acceleration and deceleration. Maybe yours haven't been mapped out yet.
    Here's an example of what I have available for my 2013 Pentastar 3.6 GPEC2 under the "fuel" "transient" tab.
