This listing is for an ECU tune for 2024+ KTM, Husky, and Gas Gas TBI models, which include:

KTM 300 XC-W 2024-on

Husky TE 300 2024-on

GasGas EC 300 2024-on

This listing does not suit SX/XC/TX/EX Models as they require different head inserts and different ECU tunes. Please see our other listings to suit these bikes.

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

  • Drastically improved throttle response throughout the whole RPM range
  • Both Green & White maps are tuned and the stock map switch (if installed) works like normal to select between the customized maps.
  • Smoother throttle response
  • Much better part throttle and low rpm power
  • Better fueling; some areas are crisper than stock for better throttle response, and some areas are richer for improved reliability.
  • Much more enjoyable to ride in virtually any conditions.

Although the TSP ECU tune can be done on it’s own, doing this ECU upgrade as a package with our TSP Insert/Head at the same time will offer much better performance gains over stock, and we strongly advise going for our full TBI power kit for the best experience.

TSP Heads/Inserts work very well when used together with an ECU reflash completing the package, and it is highly recommended doing the TSP ECU flash with a TSP head at the same time to get the best results.

All TSP mods are designed and dyno tested in-house at TSP so you can be sure you’re getting reliable performance and a quality product.

Note: In order for us to reflash your TBI 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 TBI ECU without the VIN #.
