I've had some tuning discussions in other threads, but I figured I would make a stand alone thread to make it easier for researching people to find current info. I've been searching on this forum and other forums and there is a lot of old and mistaken info out there. I've added links to stuff I'm referring to.
I recently installed the KTM performance cam, KTM hole-y airbox
, Fresco decat
, and soon will be installing the Yoshi R-77
and both DNA internal
filters. Much more air moving in and out of the engine so tuning is a must.
So I take my happy self and bike to the KTM dealer after the cam install for the famed Akra/EVO map. They don't have it or a way to load it. So I did some searching and at first I thought I was totally screwed because I found old threads before the Power Commander 5
was released. KTM keeps the Duke IV's ECU locked up tight, but the PC5 was introduced as a viable piggyback system.
Sounded great to me, but unlike better-supported sportbikes, etc like the 2009 R1 I owned there really aren't a bunch of maps you can just load up and fly with. Nice fellow Duke owners can give you their map, or you can use the 4 maps at the bottom of the DynoJet page (may be a good starting point, but more mods will require different settings than those maps probably have).
To do it yourself you can buy the extra Autotune
for around $240 on Amazon, get a bung welded onto the exhaust my a local muffer shop for the wideband (larger than the stock O2), and DIY the tune for your location.
Autotune has the ease of doing it yourself (except for the bung welding part, $30 or so) and the ~$250 price point. It is nice if you don't have access to a competent dyno near you. The AT can adjust on the fly for atmospheric conditions and changing mods from time to time. Much more modular. But it takes a bit of a learning curve and may not yield the best HP. It is not plug and play, you will need to ride the bike and input where you want the fuel changed. It doesn't do that itself.
On the other hand the dyno tune is more expensive, but should give you the most HP and best powerband for your mods in particular. The downside of the dyno only (not using the Autotune) is you better be done with your mods when you get the tune, because you will have to get another tune if you change your setup. And atmospheric conditions change, they won't always be like the conditions in the dyno room.
The best of both worlds would be to get the PC5 and Autotune to adjust on the fly, then get it dyno tuned for peak performance. That's if you want to best of the best, but the PC5 and the Autotune should yield great results by themselves as long as you are dilligent.
