The new SpeedoHealer TSD features an additional function called the Top Speed De-restrictor (TSD), which can remove the factory-set top speed limiter.
It is disabled by default. You may enable this feature only for racing purposes on closed tracks, at your own risk.
This unit can be configured to bypass the top speed limiter on motorcycles and ATVs that have a maximum speed limit based on the speed signal.
You can configure the TSD unit to either "freeze" the speed signal in the ECU at a specific limit or apply a steeper calibration curve so that the speed signal increases at a slower rate above the specified limit.
SpeedoHealer v4 is the world's leading and most popular speedometer and odometer calibrator. Regardless of changes in gear ratio or tire size, the SpeedoHealer v4 ensures accurate speed and mileage readings, providing reliable operation and absolute precision for your motorcycle's instruments.
On most motorcycles, the factory speedometer has an error margin of up to 10%. Even a small change in the transmission gears can increase the error to as much as 15%. At the same time, changes to gears or tires also affect the odometer readings, recording more kilometers than actually traveled and negatively impacting the motorcycle's resale value.
The SH-V4-TSD unit is compatible with certain SH-V4 wiring kits.
CAUTION: You must verify that the product and wiring are compatible with your motorcycle's model and year.
