My car has a fly-by-wire gas pedal, with a potentiometer mounted directly on the pedal. Some slightly older cars still have a cable going into the engine bay and turning a pot there. Either way, the pedal's position is translated into an electrical resistance which the ECU reads to know how much the driver wants to accelerate.

Since I keep an eye on the ScanGauge to adjust acceleration, I never floor the go pedal, in fact I hardly ever press it farther then 60-70% of its total travel distance.

On the other hand, the slightest, barely noticible microchange in the pedal's position can change engine load by a lot, for example barely increasing the pressure on the gas pedal can change engine load from 55% to 90%.

So this got me thinking if I could rescale the pedal's potentiometer so that the max value is the resistance when the pedal would normally be pressed 75% of the way. This would allow better resolution, making it easier to stay at the optimal load.

What do you think?
