Two Stroke Performance
The most exciting new product TSP has ever created brings new levels of tunability to the current generation of 2 stroke dirtbikes. Tuning these high tech machines has become out of reach of the average rider or home mechanic, but we are about to put the power back in your hands!
It is completely plug-and-play and comes fully optimized with one free map at no extra cost; you only need to pay if you decide to upgrade to a pro license or want additional maps.
Designed with the future in mind, it was created for current KTM group TPI, TBI and the Sherco 2 stroke carby models. Now as of 2025, we are now releasing a model of ERM that is compatible with 4 stroke models!
The ERM comes standard with a rain/dust cover, and a downloadable TSP Tuned Map to suit your 2 or 4 stroke bike! Your TSP/FSP Tuned Map can be downloaded free of charge after the device has been registered on our ERM website.
The TSP ECU Reflash Module, or ERM for short (Patent Pending # 2023901865), is a powerful handheld tuning and diagnostic tool packed full of ground-breaking features!
This product suits all the following models:
2 Stroke Models:
4 Stroke Models:
All 4 stroke models require an additional adapter cable
