Yamaha WR250R 2008-2021 - EJK Fuel Tuner (9310207);

The Electronic Jet Kit (EJK) is the most popular fuel solution from Dobeck Performance. It is the #1 EFI controller on the market for installation time to riding with great performance. The EJK is a plug and play fuel solution that comes preprogrammed for Stage 1 modifications (Intake & Exhaust upgrades). Forget downloading maps. Forget looking up settings. Forget additional tools. Install the EJK and go ride; you will have a great tune up right out of the box. The EJK offers simple on-the-fly adjustability and access to 6 modes of adjustment using three push buttons. The EJK implements DP's load based technology which takes into account changing loads for various riding conditions. Load based tuning technology provides a smooth dynamic tune up that breaks the drive cycle into 3 main adjustment zones instead of filling in an entire TPS vs RPM fuel grid. The EJK is water resistant, and comes with a 2 year warranty. No dyno time required; no computer needed. EFI made easy. This EJK Gen 3 fits the 2008-2017 Yamaha WR250 X/R.
