SHv4 Calculator

HealTech Electronics Ltd.

About this app

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.

Ratings and reviews

Does what it says it does. However I discovered when changing settings in the "estimated" option the results don't change unless I swipe the screen up on the RHS from the bottom. Also I would like to see the ability to save one's settings so that you can get the results again later without having to enter them all in again. Besides the great ideas in some of the other reviews, perhaps for V5 you could build in bluetooth connectivity and allow the app to update the unit by connecting to it that way. I'd be happy to test it out for you if I get the unit gratis :-)

Decent app but what would be nice is if you could give it observed speed vs GPS speed AND what the existing setting is. In my case I am running an specialized output on a Jeep that is around -990 but change my tires every spring and summer to different sizes. Do that and I will give you 5 stars :) I should clarify that the stock TJ speedo gear is 4 clicks per rotation but going to a VSS (specifically Novak ) is 40 clicks per rotation so the moment you take off the speedometer is pinned to Max speed so you can't use the calculator. I had to adjust it to -999 and through trial and error figure out the speed. For 35" tires I had to set it to -933 and 31" are -915.

Superb app, easy to use. Also great support as i had highlighted a issue to the developers and they fixed it with a update within a couple of days! 5 stars for the app and the Speedo Healer itself is also a fantastic little gadget.
