Description

TSP ECU Reflash for 2018+ Sherco SE Factory & SE Racing 300cc Models

The ECU tune makes a huge difference to the 300 Sherco over stock, with some key features being:

Significant mid-top RPM performance with more over-rev
Drastically improved throttle performance in the whole RPM range
Both Green & White maps are tuned and the stock map switch works like normal to select between the customized maps.
Smoother throttle response
Better fueling
Much more enjoyable to ride

Although the TSP ECU Reflash tune can be done on it’s own, the TSP tunes are specifically developed for the TSP heads and inserts. Doing this ECU upgrade as a package with our TSP Head & Insert at the same time will offer much better performance gains, and we strongly advise going for our full TSP Power Kit for the best overall performance gains.

Note: In order for us to perform the TSP ECU Reflash on your ECU, please ship us your ECU with a copy of a work order form, and be sure to include your bike’s VIN # on the work order form. We are not able to flash your ECU without the VIN #.
