If you already have a Vortex ECU, you can reflash your current Vortex ECU Here.

How difficult is this to install?

Overall, this kit is a simple installation. It involves:

-Replacing your stock airbox with the modified one.
-Routing the wired injector connection to the Vortex ECU.
-Inserting the 2nd injector fuel hose T fitting, into the pre-existing fuel line.

For step-by-step instructions, we will send a QR code with your 2nd injector kit.

What bikes does this kit fit into?

This kit works with the KTM 250SX-F and Husqvarna FC250 from 2023-2025.
And the Gasgas MC250F from 2024-2025. A 2nd injector Vortex ECU mapping is still required.

I have a Vortex ECU already. Can I remap it for this kit?
What fuel is the best choice for this kit?

We highly recommend using one of our high-quality race fuel options, from either VP or ETS. This insures the most reliable performance gains. With Pump gas, you will still highly benefit from a 2nd injector. That being said, pump gas can vary from one manufacturer to another, possibly leading to inconsistencies in performance.

HUSQVARNA FC 250 2nd Injector

I recently purchased a 2nd injector and vortex remap for my 2025 Husqvarna FC 250. It made a huge difference across the power band! The Husky is very linear and it stayed that way, just more power everywhere. I also noticed more over rev on top. This is much better than just buying a pipe. It was easy to install with clear and concise instructions. I have zero complaints. While not cheap, its still money well spent for noticeable power gains.
