As you can see in the Motec thread on the M170 (latest ECU fitted to a superbike) wheel speeds are totally wrong compared to even a ghetto GPS velocity trace (as per the Motec garmin ghetto facility logged on the ECU at the same time).

But at absolute MINIMUM I would like to see some kind of velocity trace, YES. If its based off wheel speeds then you are always going off a wrong trace then overlaid on top of that is the honesty of the calibration to make the speed reading right + the wheel slip factor added on top.

To measure velocity CORRECTLY to determine honest speed you really need a GPS signal, top shelf stuff is around 100Hz Ghetto like Motec is around 5Hz lol, either way its 1 million times better than a wheel speed trace

Consider your self edumecated LOL

p.s. To validate ANY claims of speed to distance I also want to see the hieght and slope of where you run, again any decent GPS instrument will allow this, most ECU hack boxes will not , run down hill = much much faster , most people cheat themselves LOL
