    The "Error no response" message means that you have a hardware connection problem that is preventing the software from communicating with the ECU. Are you using a bike-side harness (the harness that plugs into the ECU connector on your motorcycle)? If so, please refer to the sticky post on the homepage titled "Attention: Hardware Test for 6-Pin Bike-Side Harness..."

    I have at the moment extremely the same problem with the same ecu .. The dash appears as in the photo

    Does anyone have the solution? At this time the ecu does not work even if you disconnect the harness side

    Hi,

    That's because you did not have a successful flash to the ECU. Please reflash the ECU.

    Thanks,

    Jason A.
