So, would I be wrong in my theory that accelerator pedal requests a fuel quantity based on rpm, that quantity and rpm requests a rail pressure, and that pressure and quantity denotes the pulse width? So instead of having my pedal
map linear like I did, I pulled back the 25% pedal position by 10-30% below 2800 rpms. This took a lot of the touchy pedal away and made smoke a lot more manageable.
