My next guess would be maybe the 1.2.8 firmware was the first version on the MX that tracked mileage on the VCU? I'm not sure when you updated or if you remember how much you've ridden since but if its not that then possible the MX version just doesn't have a proper built-in odometer. And yes it is influenced by the gearing and wheels, won't be too bad but definitely requires some thinking to convert the VCU odometer into a more accurate number.I assume that accuracy would be influenced by tire size and sprocket size combinations.
I’m not sure what to make of the “odo” number of 131.
Here’s the stats from the Varg phone.
