I use tune ecu,
Have my own lead and have tried 3 different maps in mine.
The best maps are the ones listed as described
Ktm map-standard bike
Akro map-obviously for the akro can
Evo 1 map- The one I have now, Full akro system and open filter, and it runs a treat.
There is an Evo 2 map but that is if you change the cam as well..
The original map that was in the bike must have been corrupted as is kept cutting out, I pulled the map and reloaded it and it ran a lot better just from doing that, The thing is that that map had been put in by KTM themselves.
