I've been playing with the pump voltages on the map. The voltage controls the rate of fuel delivery - I.E. how close the pump gets to the theoretical 51mg of fuel max.

Apparently the highest you can set is 3.99v before you get into limp mode.

I built a version of the map with the pump voltages turned up, loaded it on and went for a run.

The onboard logging showed that it was delivering more fuel, more readily, and the car certainly seems more responsive.

I took it back off as the throttle response was bloody sharp, and would likely be a hindrance in day to day running.

Will keep it for the drag strip, as I think it may help
