Explainer: TPI Models’ Map Names

4 years ago | Words: Andy Wigan | Photos: Jarrad Duffy, Husqvarna Images

Since their introduction a couple of years ago, the fuel-injected two-strokes from KTM and Husqvarna have sold like hotcakes, in spite of their power delivery quirks. On one hand, adopting TPI (Transfer Port Injection) generated several benefits for these models. On the other, this TPI technology created a few idiosyncrasies; issues such as irregular fuelling at constant throttle settings, and the inability to adjust to fast-changing parameters in real-time. And that’s exactly why there’s been a series of updated maps developed for both the 2018 and 2019 year-model bikes (you may have heard people refer to “Generation 3, 5, 7, 8 or 9” maps etc). A bit confusing, right? Right! So let’s clear things up…

Originally, the 2018 and 2019 KTM 250EXC TPI and Husky TE250i only came with one map – the ‘Derestricted Map’, which will be Position #1 if you have a Map Selector Switch fitted to the bike (that is, the full power map), while Position #2 will give you a soft version of that Derestricted Map.

More recently, the Austrian factory has developed a ‘Sport Rider Map’ that can be retrospectively installed in the 2018 and 2019 250cc models (again, this will need to be done at a dealer who has a User Setting Tool).

For the 2020 KTM 250/300EXC TPI and Husky TE250/300i, however, the factory has refined the mapping for all four of these TPI models. Now, only the optimised ‘Derestricted Map’ is available for all 250 and 300cc models.

Our thanks to the KTM and Husky dealers who contacted us previously to draw attention to the year-model error we’d previously made in this article, which has since been corrected.
