TSP ECU Reflash Module (ERM) – Suits 2017-2025 4 Stroke Models

Introducing the new ERM for 4 Stroke & 2 Stroke Models!

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!

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 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!
