All TSP Tunes were designed with TSP heads/inserts.  We highly recommend pairing the ERM device with the appropriate TSP head/insert for best results.

All TSP ERMs come with the TSP ERM Rain & Dust Cover included!

Get it loaded up and ready to ride! ERMs are shipped without software loaded. We can pre-load your MAP so you don’t have to. Check details here.

Attention 125 TBI owners! The ERM is the only method available for tuning the 125 TBI ECU. There is not a re-flash of the ECU available.

NOTE: With the purchase of an ERM, you DO NOT need to ship us your ECU. Once you receive the ERM, you will use the ERM to download the correct maps for your bike, and you will flash your own ECU using the ERM.

Introducing the new TSP ERM v3

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 Gas Gas TPI, TBI & 4-stroke, and the Sherco 2-stroke carb models.

The ERM comes standard with a downloadable TSP Tuned Map to suit your bike! Your TSP Tuned Map 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 the v2.0 ERM device can be registered for either TPI or TBI Models. Previous v1.0 TPI ERM’s 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.

New Basic Tuning!

‘Basic’ Tuning is now standard on all ERM‘s. It is the most important update for this 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 Map, 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 customised adjustments to fuel, ignition and powervalve
  • Limits to changes apply: Fuel +/- 10%  |  Ignition  +3/-5 Degrees  |  Powervalve +10%/-10% (Powervalve TBI Models only)

ERM Tuning Features

• The ERM can store 2 TSP Tuned maps plus the Original map on the ERM (comes with one free tuned map)
• Original map can be flashed back to the ECU at any time, as often as you want but cannot be modified.
• Original Map is automatically saved to the ERM server during pairing to the ECU (TBI Models Only)
• If you have two TSP Tuned Maps 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

Dash Data

View live high speed engine data streamed directly from the ECU

Dash display for TPI models: RPM, Throttle %, absolute 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

Extras & Service Features

• Fault Codes
  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.
• Diagnostic Troubleshooting
  Diagnostic function allows the current flashed map (including any changes made in Basic/Pro) to be saved as an encrypted file and sent to TSP for checking
  
• Throttle calibration & setting TPS Voltage (TBI Models)
  The ERM allows you to correctly set the TPS voltage using the absolute throttle read-out on the ERM – critical on TBI models
• Additional screens showing various features & information

Additional Paid Features

These features can be purchased through your account on the ERM Website

• Pro Mode (Paid feature): Allows higher resolution changes than Basic Tuning according to RPM and throttle across 5 profiles.
  • (Limits to changes apply: Fuel +/- 10% | Ignition +3/-5 Degrees | Oil +100%/-50% | Powervalve +10%/-10% (TBI Models)).
• Pro+ Mode (Paid feature): Same as Pro mode, but with no limitation to changes
• ERM Reset (Paid feature): Allows the ERM to be reset so that it can be paired with a new bike.
  • Allows the ERM to be used with a TBI or TPI bike regardless of previous choice
  • Will leave the current ECU with whatever map was last flashed allowing you to keep a TSP tuned map on the previous ECU

Data Logging (TPI Models)

The ERM also allows data logging using a third party app. Just connect the ERM to your mobile device via wifi and stream data live to your phone, or data log so it can be reviewed later. This is particularly helpful when tuning and also provides a fascinating insight into how your engine is performing even for novice users.

ERM Website

The ERM website gives users all the tools they need to keep their ERM up to date, including Tuned Maps, ERM firmware updates, ERM Manager software updates plus instructions and videos.

The website also allows the user to upload copies of their original map and saved profiles so they can be kept safe and accessed again for future use if needed. Users can also purchase paid activations like Pro and Pro+ mode to enable the ERM tuning features.

ERM Manager Software

The ERM Manager software is a powerful tool which allows you to communicate with your ERM. You can save a backup of your Original Map, upload TSP Tuned Maps, view profile settings, backup profiles, save diagnostic files and much more. This custom software is currently available for Windows 10 (64 bit) or newer PC’s and MacOS Big Sur (Version 11) or newer.

Future Updates

We have a range of exciting updates planned for the future which are going to make the ERM the world standard in 2 stroke tuning and diagnostic tools. These include accessories, features and knowledge that will be unique to the ERM and allow ERM users to be in control of their engine in a way that’s never been offered before.

Additional features and ERM downloads can be found on the TSP ERM website
