Upmap Issue On 2025 V2

  1. has anyone managed to successfully use the map on a 2025 v2? After fighting to fit the decat I though I was on the home stretch. Sadly the map got to 100% then showed a communucations error. Loads of errors on the dash, the fan comes on at full blast when the ignition is ON and I get a clicking sound when off. I have emailed upmap to see that they have to say but but wonder if anyone else has had this issue and fixed it?

    The bike wont reload the old downloaded map or re-apply the new map, just fails at the final hurdle so im stuck!
     
  2. I’m guessing this is the T800 upmap? Sounds like the flash or the checksum process failed and has locked the ECU. You could try disconnecting the battery for a half hour or so and try the upload of the stock map. Don’t go straight in with the tuned map. It may be that that’s the issue.
