    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...

    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
