    Just to clarify, "small changes, one at a time" must still be applied to both cylinders, so it's actually "small changes, two at a time" for most things...

    I'd start with secondary throttle openings or just turning the O2 sensors on an off just to see how it all works.

    Keep saving your new maps and rename each time. Make double sure you have a backup to your backup of your starting point so you can always get back to the beginning and you will be just fine.

    Remember too that you can play with the software and maps from the tuneecu site without having the cable....

    Have fun!

    Thanks Steve! This is just the push I need I think. This week is slow for me, it's high time to get down into this software and learn to play it like a fiddle!

    I acknowledge the problem about the lack of tuners working on tuneECU here in Greece too. You are on your own as long as you go outside of the casual stuff, power commander etc..
    I envy you americans that you don't have to cross an ocean to have someone to tune your bike.

    That's the reason when anyone has something done to him by a professional should contribute with maps to the tuneECU cause.

    Send me a ticket. I'll pack up my laptop and cable and spend all winter in Greece tuning your bike. San Antonio TX doesn't sound too bad either.

    Hey Viola-tor,

    Great thread, thanks for starting this one. I was actually about to do the same thing by taking my 990 to AF1 and getting a dyno tune, they told me the same thing and I'm not ready to drop $800 for the work right now (EDIT: that's for the new ECU + dyno time, I'm rounding up).

    I am not too far from ya (in Austin), I have done the tune on mine I have the cable so your welcome to come up this way and you can try out some tunes, if it doesn't work out you can always go back to stock map, that's the beauty of TuneECU. I would love to get mine professionally done, but I can't afford it right now.

    Just bring some beer :freaky

    Just thought I would pile onto this thread, I just purchased a PCV and AutoTune, I'm pretty stoked to get it installed. TuneECU has been great and the only reason I'm moving to the PCV is to get the autotune setup. I've had been running a map made by Wayne Tripp (the PowerTripp Acro 2-1 exhausts) and I've been happy with it, but I'd like to put on the CPR air intake system on the bike. To do that I would need to dyno tune it or just keep trying maps. The more research I did the more I like the concept of the AutoTune, I've heard it gets you pretty damn close to a custom map. I was actually going to gamble in the spring, put on the CPR and ride out to deals gap to Ken Wheeler (because I do that trip every spring anyway, love that part of the country) to have him put it on the dyno. My only trepidation with that plan is the gamble of getting out there, if I put on the CPR and it's eating gas and I'm only getting 25MPH (not that I've seen that reported after a CPR install, but all bikes are different) it's going to be a long ride. Anyway, I'm excited for trying out this combo on the bike and I'll report back how it works out, before and after the CPR install.

    Note: that the autotune doesn't works good on low rpm's according some people on the ktm smt forum, but they found some kind of workaround.
    So i suggest to look there how to in the pcv topic.

    But you do not know which afr is the best for the most power with this way of working without a dyno.

    Mine personal opinion, i see it as a nice tool to maintain the optimal afr for the most power under all conditions.
    Build a map on the dyno for the most power and put the tuned afr values in the autotune so it can maintain these values
    Under all conditions (excluded the low rpm's).

    There is a dyno tuner near Seattle WA that uses TuneECU and has worked on tuning KTMs. I have never used his services but I know one inmate here that had his 2007 990 Adventure tuned by him and he was happy with the results although he never said what kind of mileage he was getting with the new tune. It is $175 for a dyno tune and It might be worth a call to find out more.

    I just emailed Nels at 2wheeldynoworks and asked for his Northern California schedule as his 2013 calendar is not updated yet.

    I'm looking for an experienced KTM 990 Adventure tuner using Tune ECU and looks like Nels is the one. I will let you know how it goes. Maybe group tune at Laguna Seca?? KJ

    tuneEcu is nice and free, but unfortunately it can't map a bike on the run like the PCV+autotune can. Maps on the dyno are a joke in principle, unless all you want is a WOT tuning.

    Care to elaborate, for a n00b? I got the PCV and dyno tune, and the bike is transformed to something it should have been when I bought it new. Smooth throttle and it pulls strong from 2000rpm.

    Problem is that dynos usually do not replicate well the loads an engine sees on the road. Think of a steady throttle situation. How can the dyno know what resistance to provide to the back wheel and what the aerodynamic resistance would be if the bike was on an open road?

    On the other hand, I suspect that to have an excellent map done on a dyno with a brake , then the tuning cost will be more than the cost of an autotune. Besides, if you have it, then you may map yourself any changes you do on the bike thereafter, with the added benefit of having the ability to choose between maps (eg economy map vs performance map) on the fly.

    In the next few days I will jump the wagon and get the pcv+autotune for my gen1 hayabusa (which also has an unlocked ECU like the 990's), so I will have the chance to play around a bit and share my findings of how well it does what it says on the tin, if you wish...

    Some of the tuners warn ed me that the auto tune feature can get screwed up by oxygen traving back down the outlet of the exhuast pipe and throwing off the O2 readings. I had a Bazzaz with the auto tune and when I made changes to the bike such as removing a baffle or air box changes I retuned and the bikes performance did improve.

    That's interesting and I could see how that would happen, but it constantly does readings of your exhaust so it should be able to adjust, that's kind of it's selling point. I'm still hopeful about it, I don't need my bike to be a screamer, I'd definitely like more power but the katoom is plenty powerful, I would much rather it just smooth out.

    But more importantly how much you selling that Penton for? :evil:evil:evil can you PM some pics?
