    So I recently rebuilt my 2009 yfz450r. Almost every part of the motor was replaced I have a vortex ECU. Originally it was hard to start after the rebuild and it could not crank over fast enough. Eventually I got it running with the starter for a little bit but shut it off. Soon the after I...

    Should I go Yoshi or FMF for my full exhaust on my 2017 YFZ? And which fuel tuner is necessary? Sounds like vortex is best, but is it worth the cost?

    So I have researched a bunch on which map and settings to use on my vortex but I see a lot of mixed answers. Fci intake no box, and rossier full exhaust. Only ride the dunes so always around sea level. What is a good map and starting point?

    Will I need to do the Ais delete on my 450r after installing a vortex? Or is it not necessary with the vortex since it overrides it I believe?

    2017 YFZ 450r on this I have a full HMF system, I have the GYTR air box adapter and filter on order. Of course it has the stock bog still and the HMF backfires, the machine runs and starts good but I’m looking to see if it’s worth getting the Vortex ECU. I plan on tracking it daily so I’ll spend...

    Almost brand new! Purchased this item around 4 months ago for $700 and no longer have the ATV. This product will transform your quad! Seriously it makes it run crazy hard! No more bog, no more flame outs, instantaneous throttle response, and mod ready. Fully adjustable with a screw driver. 10...

    Just bought a 2014 yfz 450r it has full dasa exhaust system with the power commander V and K&N air filter But when I’m going to turn slow in first gear the four wheeler wants to cut off but only when I’m going slow if I’m on the gas it rides good. I was just wondering if it’s the power commander...

    So I just purchased a Vortex x10 and a monster shorty exhaust, gonna order my FCI intake tomorrow and the 38 Motorsports AIS block off plates and the oil box breather from them also. I’m wondering if I need anything else for it to unleash the power. And was wondering what settings I should set...

    What settings would you run on the new version of the vortex. I know everybody use to use map 9 7,7,2 but is it the same on the newest update? My yfzr has a hmf exhaust,uni filter no lid, ais delete and 1000ft above sea level. Thank you in advanced
