Norton Racing ECU Flash Update ONLY – Yamaha R3 / MT-03


DO NOT SHIP until we have emailed you with shipping instructions AFTER you have placed your order, and it has been confirmed!


We DO NOT sell OEM ECU’s or do ECU cores, you MUST send in an ECU for us to flash.

***At this time, we are unable to flash ECUs with a part number beginning with B02. These seem to come from bikes with ABS, and we are still unable to flash them to our current race spec. However, you can use an ECU from a non-ABS bike (part number begins with 2MS) in a bike with ABS and the ABS will continue to work like normal. This has been tested.
