Specifications:

With our Speedo system you can now keep your cable actuated speedo working. This is most useful when swapping to a newer engine that hasn't mechanical output in the gearbox to drive the mechanical speedo cable, or in racing applications, when swapping to a gearbox without mechanical speedo output.

We can supply a vehicle specific speedo driver or a universal version (when there's no speedo cable available, you must use your own)

Speedo system is very simple to calibrate and it can be done by you, no need to send us any tyre size, rim, tyre perimeter for us to calibrate, nothing. While it can be done only by the person driving, we highly advise you to ask a friend to help you out to adjust the Speedo system while you drive. 

It goes with full instructions included.

Brief explanation:

You will be asked to calibrate two values of speed. For example, 50km/h and 120km/h. Ask your friend to inform you of current speed, this is nowadays easily done with a gps  speedo on the mobile phone. Increase vehile speed until GPS reads 50, set 50km/h speed. Increase vehile speed until GPS reads 120, set 120km/h speed. Done.

- maximum speedometer scale adjustment.

- initial needle full sweep when ignition on (can be turned off)
