TuneECU for your EFI KTM

[KTM-Bryon]

Applies to: KTM 990 / 1190 / 690 Duke / 690 SMC & Enduro / 690 Supermoto :clap:

See http://tuneecu.com/ for the software and

http://tuneecu.com/TuneECU_En/KTM.html for the special cable to connect to the bike.

I have TuneECU loaded on the laptop and I got my connection cable drivers working yesterday. So far I have confirmed I did get the Akrapovic FI map (KM765EU0800231FI) installed at Holeshot last year plus there are no error codes.

I hope to play with this some more after the Routledge :f: run this weekend.

Anyone else tried it?

My bike has always had a bad habit of flaming out at super slow speeds, like 1-3 kph, on the tight trails. I found this post

I checked out my bike with TuneEcu. I had 0.51V, 0.69V, and 0.71V for these three settings but now I have them all within spec. Also, in the airbox, I found water, oil, and nasty brown stuff that I think is either water and oil mixing or something that blew back out of the engine through the throttle body. The throttle body was coated in black soot too.

I hope to test run it before the Nubee ride March 25.

Time for my yearly update eh!

I messed around with the electronic throttle settings last year and next thing you know, my bike would barely run and was giving some FI error codes. I took it to Holeshot and they fixed it, no problems. Whew. It turns out it was nothing I did but rather a bad connection at one of the connectors you unplug during the procedure.

So this year I finally got the courage to mess with the fuel mapping. Here is what I posted on over at supermotojunkies.

I put on a FMF Apex silencer in addition to the DNA air filter under the stock snorkel. I loaded the Evo1 maps and test rode it last weekend. What a big improvement over Akro maps and just the DNA filter.

I then mapped the Throttle maps to 100% on performance plus mostly 100% on neutral. I left neutral where it was at high rpm and over 50% throttle. I took this for a test ride and it ran a bit better but I could still stall it at slow speeds. I thought it was detonating when I snapped the throttle open now. I topped up the tank with 94 octane gas and headed home.

Now I did the ignition timing advance, more fuel in the mid-range, and F/L switch changes.

I used post #34 from taijohnsen as a guide but added 0.5 degrees less on all the advanced ignition trim cells. Also at low speed I added nothing and even removed 0.5-1.0 degrees at very low speed and throttle opening.
I used taijohnsen's the fuel trim exactly.
I modified the F/L switch also as I am not convinced this is where the problem with my bike is coming from.

After cooling the bike down overnight I gave it a 15 min idle and took it out for a rip. WOW. Totally different bike. I could hardly stall it and cracking the throttle or fanning the clutch always got you out of trouble instead of killing the motor. It seems to pull very strong up the the rev limiter! The bike feels 50 pounds lighter off road now as it jumps when you give it some gas!

I want to put the F/L switch back to the EVO1 KTM spec and try it again to see if it makes a difference.




Here is the I trim I used:

and the F-trim:




and the F/L switch I made:

Those numbers are 5,10,20,20, 35, 35, 35, 35

Interesting results. I've not monkeyed with my EFI, as the bike rarely stalls on me, but then I'm not the madman you are !

That is very cool information!!!!! Thanks for sharing. It will come in handy for the one day i can buy my 690 :hf:

Great info! I like the idea that I could get my bike to feel 50 pounds lighter off-road. Too bad I fear with my limited knowledge if I started messing with the mapping I'd be pushing the bike before long.

I changed the F/L switch back to the stock EVO1 settings and the deceleration popping is now gone. :clap: I thought it was a bit easier to stall at low rpms as I did stall the bike a few times in some tight trails on my test ride.

I went back and changed the F/L switch at the 1000 rpm level only to 15 from 20. So now I have 15, 25, 39, 39, 39, 39, 39, 39. I then added 2% more fuel to the L maps below 1000 rpm and less than 370 pressure.

I committed the trims to the maps also. I hadn't done that before but I don't think it made any change.

I then changed the L1 & L3 and I1 and I3 maps back to factory EVO1 settings so I can switch maps on the road.

The test ride showed very good engine response :f: and very hard to stall. Maybe not as good as with the F/L switch coming on earlier but still very good. I don't have any deceleration popping either. When I switched over to the Standard map, position 3, to try it on the stock EVO1 map the bike still runs good but not as hard acceleration etc. I will leave it like this as I can't get 94 octane fuel everywhere so now I can play with her on the advanced map and still get home if I have to use 91 or 87 fuel!

Now I wanna try a few trials with +2% fuel across the entire map and also -2% across the entire map to see how the bike responds. I wanna get the most power with the least fuel. I am getting about 16 kms / litre (38 mpg) right now in mixed off road riding and I wanna go for bigger rides.
