All of the emissions are turned off inside the ecu. There is no need for any "dongles" or anything else, to keep engine codes from popping up. They would be a waste of money.
 
The fueling is designed for huge power gains and no more flameouts.It's designed around a more open exhaust, on bikes that are choked up (EXCF / XCFW/ XFW/ FE / FE-S / ES )
 
It's designed around the intake reeds being taken out of these models, and our intake tube being installed. You can also use the race bike air box or leave in if desired. But it works best with an "open" intake tract.
 
An optimized ignition curve for more power and no flameouts.
 
We almost always advance the ignition timing, depending on the bike. It's advanced at different rates across the rpm and throttle position range. This ensures stronger pulling power and lower flameouts.
 
RPM limit raised 6-800 rpm. Pulls harder and longer.
 
Still utilizes stock map switch or utilizes if switch is added.
 
2 power maps come in most ecus plus traction control if applicable and even the quick shift feature can be utilized if applicable. If your bike came with a switch, then you are good. If it's a 24-25 bike, then you can add one for all or most of these features.
 
You can choose to our "snow bike and all altitude mapping" as well. Our standard mapping is perfect, if you stay between 0-7000 ft elevation. However, if you also ride above and below 7000 ft often, then check out our "snow bike and all altitude mapping" page.
