    Well this may not be the place to ask this question but going to anyway. been reading on this tuning thing, the 15 min. or new tunes with a computer, my question to someone that's smarter than i am is, did the sas and canisrectamy. removed all the smog stuff went to wings exhaust still running the stockish air filter it's a K&N filter did the 15min idle after all was put back together still getting in the 38-42 range on fuel mileage do I need to do new tunes or run it like it is, the thing just runs and runs well.

    Thanks Mike :confused :D

    Does it pop severely on decel? If not, carry on

    38-42 mpg is quite nice

    You're probably ok but borderline if not slightly lean. The combination of the higher flowing K&N air filter, SAS and canister removal, and higher flowing exhaust come together to add more air to the mixture. The 15 minute idle can't handle that extreme of a change. I'd recommend getting the Tune ECU cable and installing the Akra map for starters.

    If you don't have ability to check the AFR on a dyno you can always remove the spark plugs and have a good idea of whether its to lean or not.
    google spark plug reading for images of what to look for and colors that tell the story.. Better to take the time to find out if its lean or not before melting a piston down.
    Decel popping is only and indication that the closed throttle range is to lean, and isn't an indication that say the cruising rpm at 10% throttle is lean and that's where engine damage could happen.

    With tunecu you can take a working map that is showing on the plugs to be a little on the lean side and increase the fuel percentage for the entire map and both cylinders just to be on the safer side until you can dyno check it under load runs.

    Is anyone using a Android Tablet to run these programs on their bike ? I have been looking at past pages but no mention that I found .
    I thought that I had read some using their phone but I don't even see that post now .

    Thanks in advance ! :ear

    Any suggestions for an '07 Adventure with stock intake, FMF Q4ti's? I installed the Akro map via tune ecu, but still have a lot of decel popping, a flat spot around 4600-4700 rpms and low RPM jerkiness. :ear

    I've got an '07 myself...leo vince with spark arrestors and stock air box. On the stock map the plugs looked OK, but it would definitely pop a lot on decel (so I believe the O2's kept the AFR in a decent range at cruise)

    I tried the akro map in the past with really heavy fuel consumption and the bike would occasionally cut out if I chopped the throttle.

    However I just removed SAS and canister, and tried the Akro map again, except with O2's enabled. Surprising to me it's actually running pretty decent (no popping for once!) and my fuel range has varied from 34 in dirt to 40 on road. Low RPM is quite smooth but I do still have a very faint flat spot in the same range you mention.

    I'd resisted doing the sas and canister for a long time but it really is running much better. Also, enabling the O2s on the Akro map might be worth a try...

    On a side note, I actually left the canister in place and am venting the tanks through it. However I removed the pump and replaced the hoses into the intake with some longer hoses that run up under the glove box and are used for TB synchronization. I think I got a much better TB sync using a simple home made manometer hooked up to my new hoses than by using the MAP sensor readings in TuneECU.

    Now that I've got it running nice, I'm planning to screw it back up with a new intake! :freaky

    I should have noted that I turned the O2's on, on the Akro map.

    Same shit here (except leo's).. I even played around with the maps by hand and I could only get it a little better without going to a dyno to see where the AFR's where..
    BUT, after removing the canister and SAS crap (with install of aftermarket intake) it runs great on the akro ktm map..
    I'd bet if you just did the canister and SAS removal it would run better..

    I bought a DynoJet Commander III for 07-08 KTM 990 ($4XX); then turned around a bought a Baja. So, I have a Power Commander III for sale @ $180. PM me, if interested. So far, he Baja has been a great experience with no popping, smooth throttle, stronger pull, and 42-43 mpg. Plus, I got a deal that I couldn't pass up.

    Can someone recommend a flash for a completely stock '08 990 to help eliminated off idle snatch?
    Thanks....

    I am running the ITG air filter with a customized map. Wings are installed with small outlets. Idle used to hang at 2500 or 4000 from time to time, not too often. I checked TPS today and was at 0.78 . I adjusted it at 0.55 and idle would hang at 5500. Adjusted it at 0.67 and was hanging at 4500 for a while, settling later at 1500. When I turned the throttle, it would climb to 4500 again. Finally adjusted it at 0.62 and it settled at 1500, then TPS moved to 0.59. The bike was at fan operating temperature 107C.
    Now it seems to idle at 2000 for a short time before settling at 1500. I will keep it this way for a while...
    I would like to ask if adjustments should be done on a cold bike? or while fan is running?
    Cheers.

    TPS is always adjusted with a warm bike (15 min ride or so).
    Engine OFF but ignition ON.
    The baseline is 0.60v when set properly (warm).

    yes, this is true, 0,60V warm engine ('working temperature').

    anyway, I have a feeling (eg. 2011 fueling copy-pasted to 2008 map), that these adjusted maps we use/make do have tendency to affect to idling speeds somehow (don't know if really, and/or why), rising them to 2000-2500 rpm for while before setling back to 1500...

    ITG foam filter -system may alter the ambient temp sensor operation comparing to stock box behavior, too. (don't know for sure, just guessing)

    time will show, still testing ITG, leo vinces and mapping... and snow is coming soon - maybe tomorrow... :eek1

    Zuber,

    Thanks for the help with the powertripp map. Just downloaded it to my 11' 990R and it really smoothed it out in the low/mid rpms. Ran great before, runs better now.

    They do have a duel wide-band logger. Would save a ton of time cause you could tune each cylinder with the data log from one ride. All their data logging ones log five options plus the wide band if I remember right.

    The inputs are only for a 5 volt signal. So, log RPM(seperate channel for this) TPS, MAP(x2) and throw in stock 0-2 sensors(x2). The wide band is a seperate logging port.

    I think about selling my single and buying a dual all the time.

    I take it that these other inputs cannot be gathered via the 16 channels of obd2 data because KTM isn't standard obd2 protocol (I read this elsewhere...maybe on this thread) or am I wrong?
