So heres the deal. I have a 14 Pro 800 with a MTNTK turbo that lost the ECU. Got another one that came off a 14 assault 800 and the speedo shows high by about 3 times I would guess. Plug another one in I have and shows normal. The RMK and Assault both have same part # for speedo pick up. All the programming numbers match up the same from ECU to ECU.
speedo way off

Dealer told me they can select if the sled has a chaincase or quickdrive when programming. They are not equal but 3 times is a bit much.
This would be normal and expected. Chaincase Assault versus the Belt Drive on the Pro.
On the Pro Ride with factory Quickdrive, the speed sensor reads the holes in the brake disc of the jackshaft. The Assault brake disc is different than the Pro Ride.
If you want to use the Assault ECU and have correct speedo readings, you will need a different flash installed into the ECU or contact Loudhandle here on the forum for a speedo converter.
one ecu could be stuck in kph not mph
LoudHandle, I need a speedohealer that's plug & play for my 19 axys xcr switchback 850 . Does healtech have these in stock with the correct connectors or do you ??
Where or who did you get it from with the correct connectors ??
I have the same problem and the dealer tried to change it with his DW and said that he couldn't
