    Hi,

    I recently replaced the super moto 17inch wheels on my qingqi with 18/21. Now the speedometer is way off.
    Anyone had any luck adjusting it? Its a digital speedometer.

    Is there a model with that wheel size? Change the speed sensor?

    Yeah the other model has the bigger wheels. I was hoping there'd be an easier way than replacing the speed sensor. Click some buttons perhaps. I will go investigate when I got time.

    Would assume speed sensor - check part numbers between the models
    Basically each turn of the wheel shows a different length in distance blah blah
    Your going slower then shown
    Did you also change the gearing? Otherwise it will rev it's tits off

    Update - found Taobao seller whom contacted the factory
    It needs another speedo head
    It seems the programming isn't adjustable externally
    Assume it's in the chip etc something to do with software or the like

    I was never able to find a Qing Qi speedo that could be adjusted, had to change the wheel sensor.
