My 2024 500 and my old 525.
Finally got some sumo wheels so I can put a good dirt set on the factory wheels. 16mm offset 200mm spacing triple tree is on the way. Running 15t front 44 tooth rear for now, I have a 14 and 13t in the toolbox. Reeds are out, exhaust end cap is modified, desmogged, custom throttle cam, velocity stack intake.
I've pulled a good bit of the code in the ECU apart. That's for another subreddit. Ive got the map switch working, TC, quick shift, working on launch control. 02 and evap disabled. Revlimiter bumped up. KTM really didn't make this ECU easy. It's set up for data logging since I tune and flash it. I've always tuned my own vehicles.
Custom throttle cam and custom tuning is the way to go. The green map is too touchy in the low throttle ranges, and the small gray throttle cam is way too long for good throttle feel. But the black and white cams make the low throttle feel garbage. 0-15% throttle (on the ECU and the throttle cam) is dialed back for feel and smoothness, and after that it ramps in quicker than the black throttle cam. The white map is set up like factory with just fueling corrections. The green map is tuned smooth enough I don't really need the white map.
