November 2025 37 Two Stroke Performance ECU Re- flash Module For 2-Stroke Austrian Brands For those not familiar with this innova ve, pow- erful tool, I'll do my best to explain what it is and how it works in the simplest of terms. Whereas the popular GET ECU (Electronic Control Unit) replaces the factory ECU, the TSP ERM is a mod- ule that allows you to download maps from TSP in Australia and then upload them to your stock OEM ECU. How it works is this: first, you con- nect the module to your PC or laptop, log onto twostrokeperformance.com and download their ERM Manager program. From there, you create an account with a username and password. The next step is to register the ERM and enter your bike info, such as make, year, and model. TSP has a number of custom maps available to download to ERM. You can choose a map that fits your eleva on, riding style, etc. You are allowed one free map (actually two maps, as you will receive green and white maps to access with your map- ping switch). Addi onal maps can be purchased by entering your credit card info. Once the ERM is registered and the map of your preference is downloaded, the ERM is connected to the bike via the diagnos c terminal (located behind the headlight on TBI models). At this point, the ERM is powered up and the next step is to connect the ERM to Wi-Fi. At this point, while connected to Wi-Fi, the stock map is copied from the ECU and saved to the ERM and the TSP map chosen is flashed to the ECU. At this stage, the thro le posi on switch (TPS) voltage is checked with the red and yellow idle speed adjusters backed out. In order for the fueling to be accurate across the en re rpm range, the TPS voltage must be set to 4.0 volts. Luckily, ours was spot on, and the TPS did not need to be adjusted. We then reset the high idle voltage per instruc ons by turning in the yellow knob. Once voltages are checked and set to specifica ons, the power valve is checked and set electronically. Yes, it might sound com- plicated, and I'll be honest; ini ally, I was a bit overwhelmed, but a er watching the TSP YouTube videos describing each and every step, I found it to be a rela vely simple and interes ng process. Yes, learning can be fun and TSPs ERM delivers! $500.00 - $530.00 For more info, visit slavensracing.com
