This video shows the basics of how I installed a speedometer calibrator "SpeedoHealer V4" on my Honda VTX1300 motorcycle. After calculating the speedometer error using by GPS as a reference, I programmed the SpeedoHealer using the supplier instructions. The results corrected the speedometer error perfectly. The installation and programming were very easy with great results.
The manufacturer is "HealTech Electronics":
