Let us know if you find out that it works with the Acewell, though it would seem that any pulse generator could be calibrated, since the internal computer has an extremely wide range of inputs.
I adapted a Suzuki adapter to be like this BMW adapter (there wasn't a BMW adapter avaliable when I bought my Acewell).
It takes a bit of calculating and the assumption that 1 rotation of the final drive means 1 rotation of the tacho drive and it's pretty accurate. Haven't tested it with a GPS yet, but the speed showing is exactly the same or just a little lower than the speed showing on the tacho of a cx500 when both bikes are running alongside each other.
I think it looks way better (and it's certainly way easier) than a sensor in the fornt wheel.
