    Any chance you can identify the exact moto-trek map you used?

    I have been away from this thread for a while an am having trouble finding it.

    Thanks

    +1, possible solution (only if you ride in similar altitudes/conditions) ticking off O2 sensors from Tuneecu...(remember you have to reset adaptation of ECU to get back to "no hickup" mode and redo the 15 mins idle trick)...

    I used his original maps from his tune that he generously makes available on his web site (www.moto-treks.com) for the source of the tables that I pasted into the OEM 07/08 Akra tune and loaded into my bike a few days ago. I recommend that anyone that considers doing this, whether with moto-treks' maps or anyone else's, compare those maps to each other using TuneECU first in order to see the differences. It is most interesting to see where some of the maps (from different sources) are the same and where maps differ from each other. It certainly makes it easy to see where the data sources are for tunes that are made available on commercial web sites, and where in the tables (and by whom) they have been revised.

    Joe,
    Would love to hear how you like the map after you have put a few miles on it.
    Cheers

    Would love to try your map out here in the UK PM sent.

    Cheers

    Well, I took the big black beast out to a narrow twisty mountain road yesterday, with mostly 2nd gear curves (and a few 1st gear curves thrown in to get my attention), and my current tune needs some work as well. Throttle response at the on/off transition is very hard to manage, even with a G2-400 cam throttle.

    As long as I am accelerating or running at higher speeds so the engine is significantly loaded, the beast does great. But holding a steady speed at low engine output, say 25 to 30 mph, is exhausting and throttle steering my way around tight turns is almost impossible. Even clutchless throttle around medium turns takes focus and faith.

    I was only able to get one additional fueling stumble, once when I slammed the throttle wide open at about 3K rpm to close a gap in bad traffic (well, yes, and also to hear that wonderful howl from the intake and Akras), and it almost lost rpm before it started pulling again. It only happened once and I couldn't get it to do so again. Hmmnnnn . . . .

    My TPS is good, throttle are balanced, MAP and barometric sensors all look great. I think I will be trying another tune once I get a full tank through this one for approximate fuel mileage.

    You need to mark the throttle tube so you will know what throttle opening is causing problems. Mostly, you'll need 0%, 5%, 10%, 15%.

    When you have problems, look down and notice the %open and RPM.

    Removed the canister and the SAS and disabled both using TunceECU (v. 2.5.3) on my 2011 990 Adventure Dakar Edition. I then installed the Rottweiler filter and loaded the 2-into-1 map from the TuneECU website. Did the 15 reset adaptation and I'm still getting the FI light blinking. I noticed that the TPS was at 0.72.

    Following the directions on this thread, I adjusted the throttle position sensor twice: first so that it reads 0.65v, and a second time to read 0.58 v. in both cases, the following error message shows up in TunceECU and the FI light blinks (a cycle of 7 blinks, then a pause):

    P0223 2nd throttle position sensor, high voltage or short circuit to battery

    I also did a 15 min Reset Adaption after the first adjustment.

    The 2nd Throttle test on the Test tab in TuneECU passes and returns the error message is replaced with "No errors". However, the FI light still blinks, and after I re-cycle the switch, the P0223 error returns. :baldy

    Is the "2nd TPS" the same as "TPS" ? Is this a reference to the TPS on the rear cylinder? Does it need to be adjusted separately from the front TPS?

    The 15 min trick works for some resetting but it WILL NOT WORK when doing this much work. KTM has a specialty tool that does a hard reset for your ECU. Save your self a lot of hard ake, bring your bike to a dealer and have them reset the ECU and load the map of your choice. Only then will your bike run properly.

    good Luck

    Are you saying that this "hard reset" is more than the "Reset Adaption" command that we have access to?

    Yes, I spent weeks going crazy trying to chase down gremlins on my bike. In the end all it took was a dealer his tool (yeah that sounds wrong LOL) and a new map. After that was fixed I put in a “Power Commander 5”, that was 2 years ago and my bike has been running flawlessly ever since. And because of the Power Commander, I’m getting better gas mileage than the rest of my friends. About 160 miles (give or take a few) to the tank. PM me if you need more info.

    It turns out the 2nd TPS was not fitted correctly on the axle of the secondary butterfly. It gave out the wrong voltage and prevented the secondary butterflies from opening. I re-positioned it on the butterfly axle in the correct way and the FI light went out. :clap

    question on TuneEcu program,while looking at the program on my laptop i noticed i cannot seem to cycle between the maps to compare them.
    I go to file then i try open map file, pick the map i want to look at,but the map on my screen does not change,At the bottom of the page it says its changed but not on the screen?
    Does the program have to plugged into the bike for it to function properly? Or should i be able to compare maps in my map file without being plugged in?
    I even tried comparing map files and nothing changes even when picking a map?

    Yeah, the compare file thing is subtle.

    Read a file. You can modify this file.

    Read the file you want to compare to. You can not modify this file

    Go to one of the maps, like fuel or ignition. Mouse down on the left column where it shows the RPM. Or, across the top throttle position.

    It will show one curve from each file. The main file as a solid line and the compare file as a dotted line.

    Thank you Zuber, I see it now. I thought i would compare them by switching back and forth between the maps . It is very subtle.
    Also i was trying to compare 2 maps which seem to be identical, the maps from Rottweiler ,one the 2 into 1 map and another the ADV990R 2011 USA rott-intake_Akra_tuneECU, which seem to be the same.:D

    Okay loaded a map today and saved the original, now wondering what is the difference between F1 and F2 on TuneECU main page? And when you load a map does it affect all the different categories like ignition and fuel?

    It drops to 28mpg off road

    The F1 map is for the left (rear) cylinder. F2 for the right. Most engines now manage each cylinder individually.

    When you read a map, it wipes all previous info.

    Have fun riding on the freeway. my 990 doesn't see that much pavement LOL. Thanks for the chuckle, ill be thinking about this "Freeway" comment next time we are blasting thru Hells Hollow. Freeway hahaha




    160? That's pretty bad = 27mpg. I'm using a slightly tweaked stock map with my Leo Vince SBKs and I'm getting 190 - 200 per tank around town & 85mph freeway cruising. About 155 - 160 off road (low gear rock gardens)[/QUOTE]

    Are we talking 160 to a full tank or 160 before the low fuel indication? An Adventure or an SE? Miles? With my stock tanks I was usually getting 160 at the reserve mark...this worked out to be close to 40 mpg. Always left the right tank down a couple inches for overflow.
    I dont like the idea of running the tanks dry as a normal operating mode...
