I've not heard of one either

I suppose one could reduce the timing by the same % as disconnecting the low octane wire. However, KTM only recommends running one tank of low octane fuel. I'm not sure if this is valid or just a liability thing. I'd rather not take the chance of damaging the motor.

It's the same thing, disconnecting the low octane cable makes the ECU work on the low octane map (I1 and I2 LOF on tuneecu)

My point was that it doesn't have to be a low octane map . That's just how it is set up from the factory. If you never anticipate needing to run low octane fuel you could remap the that ignition table for snappier response - think of it as a race map or trackday map. It would take quite a bit of dyno time to optimize the ignition map for best performance while still keeping the motor safe.

Well thats true. Or, a lower power/less responsive map on a 990 Adv for muddy trails. I've not really tried the current LOF settings with high octane to see how much power it drops.

Right on... I have my modified map as my primary ignition (I1-I2) and the stock ignition map as my low octane map (I1LOF-L2LOF) to fall back on if i don't like my changes made...
Same idea but just different from what you stated.

I suggested running two ign maps some time ago. When I was trying out new ign curves I left the old map in the low octane area. So, it was easy to compare by the seat dyno.

Sometime in the future I'm going to try putting the stock map in there for the old fuel mileage (48 mpg). Will need to test it out with the new fuel maps though.

That's actually what I've been planning to do in order to test my attempt to flatten out the stock 2008 ignition curve. Unfortunately, I had to park my bike a month ago due to elbow repair surgery and no riding for another month or two. Oh well.

Thanks, this is the info I was after. So the switch (or wire) activates a second set of tables I1LOF-L2LOF. Could be de-tuned for low octane fuel, could just be a different tune to suit style or conditions eg power map and economy map but is it only addressing ignition timing??

Cheers

Correct.

When TuneECU opened up that portion of the map for us the game was on for me...

People don't forget to donate if ya can, those boys made a great tool for us...

Probably been beaten to death, but this thread is long...

2007-2008 models?!

Are our only choices for ready-to-install maps these:

Stock map and Akra Slip-On map from http://www.tomhamburg.net/KTM_Tune_list.html

Or

Rottweiler intake and exhaust (or 1% lean, or 2% lean) from http://www.rottweilerperformance.com/Downloads.html

Any others out there?

I've read that I can swap the F, L, 2nd throttle, and F-L switches into any newer model year maps. Anyone care to give me a little more details about that? I'd like to have a bit better understanding.


Edit: Since there hasn't been any action since I posted this, I supposed I'll add to it...

My 2008 ran perfect with the stock map... no flat spots or oddnesses. But, I replaced my clogged and nasty stock air filter with an open intake system (like the Rottweiler and SW's). I want to make sure it's not running lean now with the extra air coming in, so I tried the Akra tune. Since there aren't any "open intake with stock exhaust" options, I figured "open exhaust with stock intake" may net similar fueling. I didn't have any substantial issues, but I have heard of the horrid gas mileage with this tune, and almost every post regarding it ends with people improving upon it.
So I tried the Rottweiler tune. Since it's made for open exhaust and intake, I opted for his 2% lean option, thinking that may make up for my stock exhaust. It had a horible flat spot / occasional cough / hesitation around 4-5k rpm, and just in general didn't provide the power 'kick' I had, and am wanting. A buddy of mine riding with me said it smelled very rich.
I pulled a spark plug after our 150 mile ride, but it looks pretty good.



So, in comparing my stock map, the Akra tune, and the Rott. tune, I'm seeing that the only tables that change values are the F1, F2, L1, and L2. All other tables are identical across the board.

So I took my excellent running stock tune... and made a +2% version (by adding 2% to all values in the 4 tables listed above). I'm thinking, 2% will provide enough extra fuel to satisfy the new open intake.

EDIT MORE: The Stock+2% gave me my snappy throttle response back, and eliminated my 4-5k rpm stubmle, but led to popping on decel... most often caused by a lean condition. So I've now made a Stock+4% version. It's still quite a bit more lean than the Rott. map.
(Thinking out loud: is this 15 minute idle thing really necessary every time? When it only takes a minute to modify and install a map, the 15 minute idle is a real downer. I find it hard to believe they would all sit there for 15 minutes between runs when dyno tuning).

I have the opportunity to get it on a dyno, perhaps a couple times, over the next couple weeks, but all they will do is run the dyno, and give me the graph (with A/F), no tuning. So, once I get it running smoothly, I'll go test it to make sure it's not too rich or lean.

I don't much care for maximizing power output, I want it to run smoothly and still get as good of mileage as possible, but I obviously don't want it so lean it could hurt anything.

SMT maps?

How different are the SMT and adventure maps?
For the SMT you can get a map for pretty much any combo of mod. (European maps, so add 2% to 4% in the US to account for the crappier gas)

Just had mine tuned with TuneEcu on the dyno with sniffer, and had a new map built for my 990R with Akro pipes and Rottweiler intake, and it runs great. I know before when i loaded the generic maps provided for the Rottwieler intake it was pretty good but now its stronger with the tune. And when i loaded different maps to try i also did the 15 minute idle,but with the dyno tune we did not do the 15 minute idle. And you know what? I don't see anything different in the loaded map, so not sure what the 15 minute idle is all about.

About idling and not much else judging by what the repair manual says. All it talks about is poor idling if it is not done.

To add to this... The 4% map cut the popping in half, but it was still there. I'm now running a 6% map... My stock map, plus 6% to the fueling in the F1, F2, L1, and L2. No popping. No stumbling. No flat spots. Snappy throttle. And I'm happy. I'll put some more miles on it this week, and then try to put it on a dyno this Friday or next (free dyno runs on Fridays)... to make sure the bike is as happy as I am.
