Another solution that I'm thinking to use the speedohealer to convert from km to miles.When I go at 100 m/h the signal send to ECM only 100km/h it mean I can go maxinum 180 m/h -> 180x1.6 = 288 km/h
SpeedoHealer - Electronic Speedometer and Odometer calibrator for motorcycles
I write an email to the techinal engineer of speedohealer for asking
And this is his answer
Yes, if you enable the SH''s "kph to mph" conversion mode, e.g. 140 indicated
on your meter will mean 140 mph road speed.
Probably it will also by-pass the speed limiter.
However, we do not have information on whether there is another kind of
restiction (e.g. HP) on this bike for the Asian market.
Anybody have experience with this problems.Please help me
Thanks a lot
