TSP ECU Reflash Module (ERM)

CHF 545.00

The TSP ECU Reflash Module (ERM) is one of the most advanced tuning and diagnostic tools available for modern off-road motorcycles. Designed and developed by Two Stroke Performance (TSP), the ERM puts professional-level tuning, diagnostics, and live engine data directly into the hands of riders, racers, and home mechanics.

Whether you ride a modern 2-stroke or 4-stroke KTM Group motorcycle, the ERM provides unparalleled control over your bike's performance, allowing you to safely customize engine behaviour, load performance tunes, monitor live engine data, and perform advanced diagnostic functions.

Unlike traditional ECU tuning solutions, the ERM is designed to evolve with your motorcycle. With the correct adapter harness, a single ERM can be used across multiple compatible models.

Important – USA Enduro Models

US-delivered 4-stroke enduro models must be de-restricted before using TSP performance tunes.

This typically requires:

  • Intake reed block removal
  • Upgraded or unrestricted exhaust silencer

TSP performance maps are not compatible with restricted motorcycles.


What's Included

  • TSP ECU Reflash Module (ERM)
  • Handlebar mounting kit
  • USB power cable
  • Protective rain and dust cover

Please note: Some motorcycles require an additional adapter harness, sold separately.


TSP Performance Maps

The ERM includes access to downloadable TSP performance maps.

Once your device has been registered, compatible TSP maps can be downloaded and installed directly through the ERM platform.

Depending on model compatibility, TSP tunes can provide:

  • Improved throttle response
  • Reduced flame-outs and stalling
  • Increased power and torque
  • Smoother power delivery
  • Enhanced traction and rideability
  • Adjustable engine braking
  • Higher RPM limits
  • Dual map functionality
  • Integrated traction control support

Live Engine Data

Monitor critical engine parameters in real time:

  • Engine RPM
  • Throttle Position
  • Intake Pressure
  • Coolant Temperature
  • Battery Voltage
  • Ignition Timing
  • Active Map Selection

Perfect for diagnostics, troubleshooting, and performance tuning.


Dealer-Level Diagnostics

The ERM includes powerful service functions normally reserved for professional diagnostic equipment:

  • Read fault codes
  • Clear fault codes
  • Activate fuel pump
  • Operate fuel injector
  • Trigger spark output
  • Control cooling fan activation temperature

Whether you're maintaining your own bike or running a workshop, the ERM provides invaluable diagnostic capabilities.


Fine Tuning Made Easy

The ERM allows riders to safely customize:

  • Fuel delivery
  • Ignition timing
  • Throttle response
  • Engine braking

Adjustments can be made quickly and reversed at any time, allowing you to tailor your motorcycle's behaviour to your riding style and terrain.

From technical hard enduro to fast-flowing trails, the ERM gives you complete control over how your motorcycle responds.


Future-Proof Platform

Designed with future compatibility in mind, the ERM continues to receive regular firmware updates and expanded model support.

As new motorcycles and tuning features become available, your ERM evolves with them—making it one of the most versatile tuning and diagnostic tools available for modern off-road motorcycles.


Firmware Requirement

For access to the latest features and compatibility updates, ensure your ERM is updated to the latest firmware version before use.
