TSP ECU Re-flash – KTM/Husky/Gas Gas 300cc TPI

Re-flashing of your STOCK ECU with improved fuel, oil and ignition maps developed by TSP, provides much better performance gains over stock.  We modify both Map 1 and Map 2, with a more noticeable difference between the maps compared to the stock maps. Both maps have more oil everywhere compared to stock, increasing lubrication and longevity of your motor.


Your bike's VIN# is needed for all ECU Re-flashes. Typically 17 characters and can be found on the bike's frame steering tube or registration/pink slip.

TSP ECU Re-flash for KTM, Husky & Gas Gas 300cc TPI

The ECU tune makes a huge difference to the 300 TPI 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 Re-flash 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 TPI Power Kit for the best overall performance gains.

Note: In order for us to perform the TSP ECU Re-flash 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 #.
