## SHv4 Calculator Description
Use this free application to calculate the speedometer error of your vehicle and generate setup instructions for your SpeedoHealer v4 module. You can also access troubleshooting information.
After installation, it does not use internet connection, it's Ad-free.
On most modern motorcycles, with factory speedometer error being as high as 10%, even a modest sprocket gearing change can have the speedometer off by 15%. The sprocket change will also cause higher odometer reading, creating a negative resale factor for no valid reason. The SpeedoHealer is an inexpensive, convenient and very simple way to fix your speedo and odo. Compatible with all motorcycles with non cable driven speedometer.
Plug 'n go SH kits are available for selected Harley, Honda, Hyosung, Buell, Ducati, Kawasaki, KTM, Suzuki, Triumph and Yamaha motorcycles.
The SpeedoHealer can also be installed on cars which have a 2- or 3-wire speed sensor.
Please check out our website for other cool and useful products for your motorcycle.
