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 help
