What Is the TSP ERM (ECU Reflash Module)?

What Does the ERM Do?

The Two Stroke Performance ECU Reflash Module—commonly called the ERM—is designed to give riders direct access to their bike’s ECU without needing a laptop, dyno session, or dealership visit.

Using the ERM, riders can:

• Flash tuned ECU maps
• View live engine data
• Diagnose fault codes
• Switch between performance profiles

Unlike piggyback tuners, the ERM directly communicates with the factory ECU, allowing deeper control and cleaner integration.

Who Is the ERM For?

The ERM is built for riders who want:

• More control over power delivery
• The ability to adapt to terrain or conditions
• On-bike diagnostics without dealer tools
• A future-proof tuning solution as updates evolve
