a follow up from Healtech: Still need to "trick" the ecu into thinking the bike is going slower as they say below. We could also calibrate it so in metric, the digital speed would really be mph. The ecm would just think is kph and not near the speed limiter. Either way, this is a way to get around the factory ecu speed limiter.
On most motorcycles the factory speedometer error can beas high as 10% and this also result in higher odometer reading.
When you calibrate the speedometer e.g. by -9%, thismeans the speed limit point is raised by 9% too.
E.g. if the bike has a speed limiter at 250km/h, with the-9% calibration the speed limit point will be increased by about 22 km/h.
So if the bike has about 9% speedo error then calibrationgives +9% top speed.
Normally the bike does not have more power anyway todefeat resistance.
If this is not enough, we recommend to get the SH-V4-ABmodel.
Program a calibration value to memory bank "A"which makes the speedometer accurate and program -50% to memory bank"B" to halve the indicated speed and defeat the top speed limiter.
You can switch between the "A" and"B" memories with a remote switch while riding.
