    Well, if Nanocom say it's all right, then I'm scratching my head!

    I just did a moving test in the driveway with the Nanocom talking to the ABS computer.
    I noted that all 4 sensor voltages were similar (within about .1 V of each other); both stationary and when moving.
    At stationary, I had 3 wheels on 1.7km/h and one at 404.8km/h; then when moving, 3 wheels were doing 2.7km/h and the fourth was doing 396km/h!
    (And I hadn't disabled TC; so I wasn't doing either!)

    So I suspect that the speed may be a miscalculation in converting the sensor volts/frequency into km/h.

    Whilst the D2 speedo wont show lesser speeds, the ABS ecu generates a distance/speed pulse for every 200mm travelled plus a 1hz base pulse.

    Left hand rear wheel. Same one as yours.

    Are you running firmware 2.03 on the Nanocom?
