MX DIRT / OFFROAD ECU MAPPING
30 Day Satisfaction Guarantee (Learn More)

FOR KTM, HUSKY & GASGAS 2019-2025 SXF/XCF/FC/FX/MC
This does not void the factory warranty. There are 2 sides to the ecu. The E prom side and the tuning side. Dealers only check the E prom side, and we don't change anything in there.
It has a 30 day money back guarantee. The only ECU service in the dirt bike industry that has this. You have nothing to lose. Not even a competing aftermarket ecu, at more than twice the price, has a satisfaction guarantee.
Advantages for MX Offroad Bikes
-
No more herky jerky throttle right off of idle.
-
No more flameouts.
-
Stronger yet smoother from idle all the way to wide open.
-
Map 1 (white), is the stronger of the 2 maps. This is the default map if you do not have a map switch.
-
Map 2 (green) is less aggressive from 3000 - 5000 rpm. From 2-3000 rpm, the two maps are the same to avoid flameouts.
-
You can only make something more docile, by reducing ignition timing or adding fuel, and these both would cause more frequent flameouts around idle speeds.
-
Traction control still works in both maps.
-
Quickshift still works in both maps.
The ECU remap is designed to perform as well as, or better than, any aftermarket ecu out there, and at less than half of the price.
Recent MX Mapping Reviews
"Just got back from my normal offroad test loop. It has it all to test. I'd do a loop with the stock ecu and then switched. It was better everywhere. And I mean everywhere. I could ride a gear higher and even when I did, I couldn't get it to flameout. And it pulled so hard in 3rd gear, that I just kept on trucking instead of having to shift into 4th briefly. Really good job and thanks for letting me be a crash test dummy."
Mike in Victorville, CA on a 2023 FX 450
"We took 3 of the ecus out with us today on our main snow hill. We have a 2nd gear hill, a 3rd gear hill and a 4th gear hill. We had the PR2 vortex, as we discussed before and a EJK piggyback. You could make the piggyback run a tad better on the very top, by adding a little fuel.
The vortex, with the snowbike tune, always did a bit better than that, but was just supposed to be used for snowbiking and not great for offroad. Then the one you sent, marked " tester C ", destroyed them all. Testers A and B were good too, with B being better than A. But C had the pull and extra top end pull we wanted.
Jake says at this rate, we are waiting for ecu " D ". Seriously though, our data acquisition showed 2 seconds faster up the 3 rd gear hill and 4 seconds faster up the 4th gear hill. We did a few times to confirm and always right about there.
Jake says sell those things. The fact that you said this was the offroad favorite as well, is most exciting. One ecu for all seasons.
