Healtech Sh-v4-ab Double Setting Control Unit

SH-V4-AB control unit with double setting, with setting selector, use with specific wiring.

Speedo Healer SH-V4 with max speed booster
3 functions in 1, it's a speed recalibrated.
On Japanese bikes, the odometers have large deviations, and if you change the pinion or crown, the deviation increases further.

The SpeedoHealer allows you to cancel the deviation of the digital odometer of the motorcycles and then display the correct speed. By recalibrating the speed, it allows you to eliminate the speed limitations in 6th gear on some Honda and Kawasaki motorcycle models.
Stores the maximum speed reached, which can be recalled via a button
Converts miles per hour to kilometers per hour and vice versa.
100% waterproof
Allows variations up to -99.9% to +9999.9% in 0.1% steps
Motorcycle-specific harnesses are sold separately from the ECU.
