(ECM 12407)
The Edge Sport/Fusion Sport are set to 1.50 from the factory, while the F-150 is set to 1.25, and the Mustang 2.3L is set to 2.00
It's been a long time since I've taken anything related to feedback processes, but looking at the application it seems like the Mustang being the lighter of the 3 platforms would want a faster throttle response and have a higher gain? Would it be feasible to increase this setting for a faster response?
