Introducing the Two Stroke Performance ECU Reflash Module (ERM)!
The most exciting product TSP has ever created brings new levels of tunability to the current generation of two stroke dirt bikes. Tuning these high tech machines has become out of reach of the average rider or home mechanic, but TSP is about to put the power back in your hands!
The TSP ECU Reflash Module, or ERM for short (Patent Pending # 202390 1865), is a powerful handheld tuning and diagnostic tool packed full of ground-breaking features.
Designed with the future in mind, TSP created the ERM for current KTM group TPI, TBI and the Sherco 2 stroke carbureted models. 2018-2023 TPI models are available NOW, 23-on TBI and Sherco 300 models will be available later in 2023.
The ERM comes standard with a TSP Tuned Map to suit your bike! Download your TSP Tuned Map free of charge after the device has been registered on the ERM website.
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.
When purchased the ERM comes in ‘Standard’ mode… ‘Standard’ mode allows you to flash either the Original Map or the TSP Tuned Map to the ECU as many times as you like. It also allows all other functions including live dash data, read/clear fault codes and data logging. When Pro or Pro+ mode is enabled the ERM also gives you the freedom to make your own adjustments to both the Original Map and the TSP Tuned Map. Pro mode allows moderate adjustments to maps, while Pro+ mode allows unlimited changes and is suited to more experienced tuners. Pro and Pro+ are paid activations which can be purchased once the ERM has been registered.
Tune fuel, ignition, oil and power valve anywhere, anytime!
The most exciting feature of our ERM is the ability to not only store multiple maps but also to adjust engine parameters within seconds. This give you the freedom to adjust your engines performance, anywhere, any time, all while retaining the factory ECU. The ERM pairs to your factory ECU, saving a copy of your original map, which can be backed up to the ERM Manager software on your Desktop.
Making adjustments to fuel, ignition or oil is now much quicker and easier than re-jetting a carb! The ERM can also tune power valve settings on applicable bikes.
‘Profiles’ are the feature on the ERM which allow you to adjust engine parameters. Modify and flash a profile to the ECU within seconds, allowing you to immediately feel the difference!
You can store up to a total of 10 profiles:
- 5 Profiles for your TSP Tuned Map
- 5 Profiles for your Stock Map
Each profile allows adjustment of parameters:
- Map 1 & 2 Fuel Maps (EFI models only)
- Map 1 & 2 Ignition Maps
- Map 1 & 2 oil Maps (Oil injected models only)
- Map 1 and 2 Power valve Maps (TBI & Sherco Carb Models only)
Live Engine Data
Having the ability to tune is one thing but knowing where to make changes is another, that’s why we’ve included an array of high speed data streamed live from the ECU. With its fast refresh rate this data can be used to accurately pinpoint areas of adjustment.
The main dash screen shows rpm and throttle in large text, ideal for a quick reference while riding. A secondary screen shows more in depth data, ideal for workshop use.
Read and Clear DTC’s/Fault Codes
Our ERM is also a smart service tool which can read and clear fault codes, enable throttle position sensor adjustments and check temperatures with a range of exiting additional planned features.
The ERM also allows data logging using a third party app. Just connect the ERM to your mobile device via Wi-Fi to 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.
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 or newer and MacOS Big Sur (version 11) or new.
