    Polaris: Which Controller To Select

    Currently we support two Polaris ECUs. The M17.8.7 and ME17.9.74.

    If you are reading your Polaris and the controller does not auto select the controller for you, it just means we haven't seen that exact operating system before.

    If your Polaris has electronic throttle it uses the ME17.9.74. Cable throttle uses M17.8.7.

    Hey eric I am having a validate check sum issue with my me17.9.74. It will act as if it has read the entire file and then right at the end of the upload it gives me a validate check sum failed message. What am I doing incorrectly or what do I need to do Thanks

    Hiya. I've got the same problem here. I have to select the hardware as it doesn't automatically recognise it. I select ME17.9.74 as suggested above. Its a 2017 ranger 570 electronic throttle bodie. Read the ecu and it says "validate check sums error" arfyer 15 minuets of trying to read the ecu.

    Any fix for this yet? I have opened a ticket acouple of weeks ago but no progress has been made as far as I know.

    Thanks for any help!

    Josh.
