Nels Byersdorf at 2 Wheel Dynoworks is the “go to” guy when you need to change the performance of the engine on your Super Tenere. What Nels mainly does for our bikes is to retune our electronic control unit “ECU” (the computer brain in our bikes),the main improvement is he makes the bike run smoother with a much improved throttle response. Even when our bikes are throttle by wire, the modifications make it feel like there is a direct cable between your hand and the engine. Another thing that’s possible is he can also program your bike to run on different fuels from regular unleaded to NASCAR race fuel. Just be aware that if he resets your bike for another fuel, that’s the only fuel it will be able to run on until it’s re tuned . Adjusting fuel economy is possible also.

Getting your ECU re flashed, you have a few options: Go to his shop in Woodenville, or remove and mail your ECU to him. Turn around time is quick at a week for about $350.00. Your bike shouldn’t need to be put on a Dyno unless you have it set up bike differently then the current “maps” he has on file. (different header or muffler combination) When your ECU arrives,Nels installs it with the “ECU Unleashed” program

He has asked that if you have ever had your bike re flashed by 2 Wheel Dynoworks, please contact him with feedback weather good or bad, its valuable information he needs to get out a better product and service.

I’ll be planning a tech day with him later this fall or winter, we hope to get a Super Tenere on his dyno so he can show us in person what he does and how he does it. Anyone want to be first in line? Let me know!

  1. Nels did my 2012 Super Tenere last year and we put it on the Dyno . I went from the stock maps to “his” maps and there was a huge difference ! I have a few video clips of my bike on his Dyno . ( I was at the PNW Cleum ride last year 2014) , I was part of the Canadian content but from the mainland not the “rock” as you call it . Nels is a great guy and is more than happy to accommodate and explain , although he has no idea why anyone would want to run in any other mode than Sport !! ha ha
