The thing is that I can live without the last 25% of travel without even noticing. I've noted (and Euromodder, who has the same engine) that in most situations max acceleration is within the first 30-50% of pressing the gas pedal, any more and at best more fuel is used, but without more acceleration.
A none-linear resistor would be great, but not in my case, as 80% engine load is sometimes seen with the pedal pressed halfway, and sometimes only 10-15%.
I have thought about a hand operated lever on the steering wheel (a few ecomodders have done this, but with a bicycle gear shifter operating the throttle cable), or at least a switch which would let me choose between stock and improved resolution, but I'm still wondering whether I'll do this mod. If I actually go into this, then I might just
limit the max engine load to 80%, or to its best BSFC.
