Introducing the new TSP ERM v2!

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, Husky, and GasGas TPI, TBI, and the Sherco 2-stroke carb models. New ERMs built from 2025 on which have a fourth, female 2-pin connector are also compatible with KTM Group 4 stroke models.

The ERM comes standard with a downloadable TSP Tune to suit your bike! Your TSP Tune can be downloaded free of charge after the device has been registered on the 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!

The ERM can be mounted to the handlebars to view live data while doing testing, but it does not need to be mounted to the bike at all times, or even at all! The ECU can be re-flashed and saved with the changes made, and then the ERM can be packed away safely. The ECU tuned with whatever changes saved will stay on the ECU unless you plug the ERM back in and make more changes.

The ERM cable connects to your bike via the diagnostic plug and the device can either be operated handheld or safely mounted on the bars using the optional mount. The tough construction means that your ERM will be safe under normal riding conditions (light rain, vibration, dust, etc) and when used on the bars it allows you to view live dash data while riding or pull up on the trail to make mapping adjustments.

Suits both TPI & TBI Models!

The v2.0 ERM device can be registered for either TPI or TBI Models. Previous v1.0 TPI ERMs can be updated to v2.0 free of charge via a firmware update. The ERM can only be paired to a single bike at a time, but it can be reset giving you the choice between TPI/TBI models again.

Tuning Features

• The ERM can store two TSP tunes plus the Original tune on the ERM (comes with one free TSP tune)
• Original tune can be flashed back to the ECU at any time, as often as you want but it cannot be modified.
• Original tune is automatically saved to our server during pairing to the ECU (TBI Models Only)
• If you have two TSP Tunes saved on the ERM, both can be modified by the user through Basic, Pro or Pro+ modes (Pro and Pro+ Additional extras)
• Your ERM can only be paired to one ECU at a time

Basic Tuning

Basic Tuning is standard on all ERMs. It is the most important update for the v2.0 release as it gives every user the ability to make simple but effective changes to maps:

• Basic Tuning allows every user to make changes to both map 1 and map 2 of each tuned TSP Tune, according to RPM and Throttle
• Basic Tuning comes with several preset adjustments (richer, leaner, softer) which can be selected by the user.
• Basic Tuning also allows every user to make customized adjustments to fuel, ignition and power valve
  • Limits to changes apply: Fuel +/- 10%  |  Ignition  +3/-5 Degrees  |  Power valve +10%/-10% (Power valve TBI Models only)

Tune fuel, ignition and power valve (TBI Models) anywhere, anytime!

Advanced Tune Settings (New in v2.2!)

Advanced Tune Settings is standard on all ERM’s with the free v2.2 update! This allows modification of advanced parameters that suit riders in specific scenarios, such as when wanting to switch between pump and race fuels, adjusting the fan activation and cold start fuel addition for extreme temperatures, and adjusting for high ethanol pump fuels in regions such as Thailand and Brazil.

Fuel Type Adjustment

The stoichiometric ratio determines how much air is required in order to burn each unit of fuel. For example, regular unleaded pump fuel has a stoichiometric ratio of 14.7:1, so it requires 14.7 units of air to burn 1 unit of fuel. The lower the stoichiometric ratio the more fuel is required to keep the engine safe.

Available for TBI and TPI models in v2.2.1

Fan Activation Threshold

This setting determines the activation temperature of the cooling fan. Stock is 85 – 90°c / 185 – 195°F depending on the model, and the fan will turn off 5°c / 10°F below the on temperature threshold.

Cold Start Fuel

At startup the ECU adds extra fuel for the first 1-2 mins when the engine is cold. This setting changes the amount of extra fuel added. When set to zero the ECU will still deliver the normal fuel load, without any additional fuel.

Dash Data

TBI Dash Screens

TPI Dash Screens

Dash display for TPI models: RPM, Throttle, Throttle voltage, Map choice, coolant temp, CCP Pressure, Ignition Advance and battery voltage
Dash display for TBI models: RPM, Throttle, Powervalve opening, throttle voltage, Map choice, coolant temp, Ignition Advance and battery voltage

Map Indicator and Selector (TBI Models)

The bar at the bottom of the dash pages displays Grey or Green to indicate which map has been selected. For TBI models, there is a new map selection page under ‘Dash’ which allows you to change between white and green maps without the OEM map switch. Map choice is saved in the ECU when turned off or if the ERM is disconnected

Diagnostics

Read and display a list of fault codes on both TBI and TPI models. You can then clear the fault codes with the press of a button.

Service Functions (New in v2.2!)

Perform a range of useful service functions, to diagnose issues and reset adaptive values.

Available service functions include:

• Fuel Pump: Run the fuel pump for several seconds
• Ignition: Activate the spark plug 2-3 times. Do not touch the spark plug during this test.
• Injector 1 / Injector 2: Activate the injector 2-3 times
• Oil Pump Prime: Prime the oil pump. Selecting this will open a new window which allows you to stop the priming sequence if necessary
• Power Valve Reset (TBI Models): This opens a window which allows you to re-learn the PV servo limits.
• TPS Reset (TBI Models): This opens a window which allows you to re-learn the TPS minimum value. It is important to follow the instructions provided closely.
