    Question AFR Command VS WIDEBAND

    im tuning my 2012 chrysler 300C V8 5.7L and have a hard time to get close to what i want. AFR Command is set at 12.50 at WOT . I disable close loop , i tune my NN for city road and now im tuning for WOT. I do my first pull in third gear about 2000/RPM-5000/RPM i have to much fuel like -13 so remove -10 of fuel in this range, do another pull and nothing change ? I was thinking is my cat protection but the cat dont get to C for enable the protection so im confuse... Do i need to lower my VE Bank1 and Bank 2 in this range (WOT) Do my ECU tink that i have more air in the engine that actully is ? Need helprsdrfdf.pnguuuuuuuuuuuu.png

    You can log the power enrichment, activate the channels for it.

    Power enrichment can be set over two different tables in your software, depends on the trigger for it.

    You even can set cat protection higher for testing.

    Log file and tune helps…

    Post a full log which has both closed loop and open loop data.

    Your OL actual EQ seems to be overshooting the commanded by 14-15%. Do your fuel trims in closed loop show similar correction %?

    This could be bad injector data or bad airflow model data.

    If you have ANN turned on, then changes to the Bank 1 and Bank 2 VE tables won't do anything for you, as the neural network provides the airflow data instead of those VE tables which are in the Speed Density tab.

    Add both the FA Power Enrichment channel as well as the FA Enrichment channel to your logging. When COT is enabled, you will see FA Enrich activated but not FA Power Enrich.
