Introducing the new TPI/TBI ERM v2.2
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, 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.

Was easy to use and straight forward

I have a ‘20 250 xcw. I have a BRC throttle body and the ability to make some minor adjustments has been great. I appreciate the ability to make maps and save them. I have two maps saved to run it as an irk or just the BRC throttle body

Amazing tool

I purchased the ERM so that I can make some tuning changes to the tsp map. It is very easy to use and I have made some adjustments quickly on the trail. Moto is ‘20 250 xcw with tsp high head and BRC TBI.

Purchased for my 2024 KTM 300 XCW. Cleaned up the overly rich bottom end on my bike and allows some adjustment for me to fine tune. Really a great value for what it does.

I just started to do business w Steve and South Bay late last year 23′. So far the quality of the products and, more importantly, the level of support have been top notch. Steve is very attentive and clearly cares about his customers. He always gets back to my technical questions very quickly and follows through to make sure we were successful w the solutions.
They definitely have earned my trust and loyalty.
Buy w confidence!
oh ya…the ERM is Awesome too!! 🙂

Items received very quickly, small glitch running the setup on Mac but was resolved same day
Gary Saya (verified owner) –
Ran too lean in stock tune. Good thing that I could add fuel.
Dustin (verified owner) –
The 2024 TE300 factory map was too rich and ultimately unrideable at 4000+ feet. The TSP ERM with suggested TSP map greatly resolved bottom end and midrange richness. Pro mode allowed for finer tuning and custom power delivery similar to a Beta Xtrainer in the white map, and a TX300 in the green map.

Best thing you can get for a fuel injected Moto. Extremely easy to use. I installed this with the tsp irk and head.

shipped quickly and everything went smoothly

Excellent product. I bought the ERM with the medium head insert. Incredible difference on the low and mid range but still fully controllable. I haven’t even had to tweak anything it’s running so good with the map they provided.

I purchased the ERM with trail map for my 2023 300 TBI. I was skeptical at 1st. Well folks if you are on the fence don’t be . This thing is the bees knees works amazing . Running trail tune with a TSP powervalve cover . My 300 has more torque and pull then my BRC500 this tune puts that BRC500 to shame . I am a happy camper thanks Steve for your help and support

This thing is great! I was initially planning on a “tune” only. Based on other reviews the increased functionality of the ERM became the obvious choice. Excellent product!

The TSP ERM is definitely a must-have for anyone who owns a TPI/TBI but misses tuning their carb to fit their riding. Thanks South Bay for the quick shipping and awesome support!

All these 5 star reviews and I couldn’t bring myself to rate it lower if I tried. If you put one thing on your machine this is the mod to do. I can think of nothing I’ve ever used that had such a huge impact! Up here in the high desert the ERM isn’t just nice to have, it is a must. On my 2024 KTM 300 it went from being way too rich down low to being perfectly crisp and clean. The baro sensor on the stock bikes can handle some changes but the stock bike isn’t a closed loop system – the ERM allows me to dial it in perfect for any condition with just a few easy taps. Even at sea level the improvements are very significant. I think KTM runs overly rich in an attempt to protect the motor at the expense of rideability. The ERM gives you the rideability back and with added oil in their maps it provides the engine protection too. I give the ERM my highest recommendation – best money I ever spent on a bike.

Great product, allows you to easily download maps, tune, read codes, reset power valve and plenty of other cool stuff. Easy to use, only problem is small screen on some setup, otherwise a none issue. Recommend product.
