Dynojet recommends setting a base map closest to your current setup that way the auto tune (AT) doesn't have to make major adjustments on the fly. AT also limits itself to how much it'll adjust as a fail-safe so if your AT is reaching the limit of that fail-safe then you may not be getting the best tune.

AT isn't necessarily a set it and forget it kind of device if you want the best possible tune. AT keeps track of how much it has to alter from the PCV base map and there's an option in the PCV software to commit those trim levels based on the AT calculations. Kev performed a bunch of testing on this and found out the readings can be thrown off quite a bit in situations such as engine braking so he recommended you run a few tune sessions to get the most out of the tune. You can find his work somewhere in these forums but searching through the hundreds of pages can be daunting. Here's what I ended up doing with my dad's SMT (same setup as yours except stock front sprocket and runs the Rottwieller filter) based on what I found:

1) I loaded the bike's ECU with the closest map to my configuration that I could find online using TuneECU. Not necessary but I only did this in case something failed on the PCV and I could by-pass the PCV and safely run the bike using the bike's ECU.

2) I kept the default tune loaded from Dynojet because I wanted to see how much the fueling had to be changed based on his mods.

3) I made some full throttle runs in a high gear such as 3rd or 4th gear if you can pull it off legally keeping these things in mind:

- Watch some dyno tune videos. Take note of the gear they hit before they lay into it, how they manage the throttle and avoid the rev limiter.
- Don't engine brake! (Kev noted some wacky readings during engine braking). When you reach the top of
the RPM range just pull the clutch in and let the bike idle back down.
- Don't be abrupt with the throttle, ease into it.
- Try to get a full rev range reading - Start at 4k, roll into full throttle then try to get to the top of the RPM
range without hitting the rev limiter.
- Do this a few times and plug in the computer. Get the reading in the PCV software and commit the trims.
- Rinse and repeat a couple more times and you'll see the AT doesn't have to tune nearly as much anymore.

Thank you for that, much appreciated. One problem, I don't want to add a power commander to the system, but tune the ecu directly.

I spoke to one place in Cheltenham yesterday, but they prefer the PCV option, but did say I could plug my laptop in, and use tune ecu to adjust where necessary whilst it's on their rolling road, where they can show me on a graph any positive, or negative spikes, but did warn me that it could take 3 - 4 hours.

I'll be looking around elsewhere to see if there are tuners out there that will tune her without fitting a power commander.

But, thank you for your advice, I will be looking at videos using tune ecu, (which I've read many times that it's a 'sinch' to use on this website, and in the SMT facebook group!!) the more knowledge and information I get, the less chance I'll have of destroying my beloved bike!!
So if anyone knows tuners preferably relatively close to Worcester, please let me know.
Many thanks again, Rob.

Thanks kevxtx, but am I being a little mentally challenged here? Doesn't that require a power commander to be fitted? Or am I missing something?

If you are going to use Power Commanders Auto tune then yes you need a PCV as well, would build the map then remove the Auto Tune.

You can also tune the ECU directly with Tune ECU but would need to find a Dyno Tuner to do this for you. I would import one of the custom tunes from the forum's first page then head to the Dyno as this will save some time & money as you will be 95% there & wont be paying for a full map.

Thanks Kev. Just to complicate things, I thought the main dealer that fitted the full Akrapovic system removed the O2 sensors, but looking at my bike, it appears they haven't.

O2 sensors not removed.
Will this suffice, or can the O2 sensors be turned off with tune ecu without having to fit the dummy plugs, and just blank off the holes?
Thanks in advance, Rob.

Do you guys think this might be worth the $50.

I'd like to start using TUNE ECU without having the need for Dyno tune.

Hi 'roblund6'!

IF I'm right, there is no need to dismount the O2-sensors, BUT you have to disconnect the other end of the O2-cable and mount the dummy plugs.

Can't tell about if it's possible to 'cut off' the O2 via Tune Ecu...

I would leave the O2 sensors connected if you flash them off,best option is to remove the sensors once flashed off & fit O2 sensor bungs.

Thanks for all your advice folks, much appreciated.

Now I'm off to my 'man-shed' to find an M8 tap to thread the holes where the secondary butterfly shafts were, fit titanium bolts (with seals) and a little high strength thread seal/lock, long enough to slightly protude into the throttle body bores, then machine them so they're flush. Wish me luck! I'll post pics when possible.

One question Guys,

Power Commander webside says that from KTM 990 SMR 2012 should be fitted with AT-200 not 300....
I asked the guys about the AT-300 but they said there's no point. unfortunately, the AT300 isn't shown as being a suitable fitment by Dynojet for my bike and may well not work so I've been told...

this is what they said

"Basically, if you have a 2 cylinder bike with a PC5, you have a choice to use either the dual channel kit (AT-300) or the single channel kit (AT-200). The dual-channel Auto-tune kit tunes better, but is almost twice as expensive. Some people don’t feel the gains outweigh the cost, but others might. It’s debatable, I guess you could say. I think the gains to be made with dual channel over single channel are dependent on the bike model. On an air cooled V-twin you know the cylinders are going to need different fuel quantities because of the cooling differences, but a liquid cooled side by side probably would not benefit much, if at all. It’s a judgment call the owner will have to make. Also, if the original manufacturer of the bike has an o2 sensor for each cylinder, you can bet there is a reason behind it. These are all factors you can use to help make your purchase decision."

So I bought AT-200 But now considering changing it to AT-300 what do you think guys?

The AT-300 works fine with a PCV on a 990, 1190 & 1290's, If you want to build one fuel map for both cylinders using the AFR off one cylinder then the AT-200 is OK, if you want to build a fuel map for each cylinder the AT-300 is better & will give better mapping results faster.

With a AT-200 will you have to keep moving the O2 sensor from cylinder to cylinder if you want 2 separate fuel maps, with the AT-300 you can map both cylinders at the same time.

I can share my dyno-tuned map using tuneecu if anyone needs to try:
Mods:
DNA MK3,
SAS blocked removed and switched off through tuneecu
O2 sensors blocked removed and switched off through tuneecu
Second flies in and used during tuning
EPC ON (I tested off too, not much difference on power and higher consumption)
Leovince cans
Sprockets 17-42
Map #20 as base map

Location Greece, fuel 95

However, always a custom map is better
I sent email and a private message, please share.
Thanks & Regards

So a few weeks ago I bought my 990SMT. Great bike. I've been reading all the forums ever since and managed to gather a lot of intel since then. Seems like this bike is an unpolished diamond.

Image

I'm busy modding mine and I'm almost done. Though I've come at this point where I do need some help with the setup. Hopefully there's someone who can assist me! My setup is as followed:

-Remus mufflers w/ DB-killers insterted
-Std. stacks and airbox, but with a K&N sportfilter inserted
-Removed secondaries, shafts in place
-Removed SAS
-O2 in place, will turn it off in tuneecu.
-EPC in place, will also turn it off.

Can anyone recommend me a mapping? I'm a bit confused because of my K&N insert, though I'm sure it won't affect it that much. Also, I'm from Europe (Netherlands) so if the mapping requires a different A/F ratio please tell me, so I can adjust it.

Thanks a lot ;)

Have a look at page 1 to pick your final map.

Perhaps this one will do:

#9/ Kev STD Air Box RC8 FINAL 19.8.12.hex
Standard air box, standard air filter, snorkel installed.
Can be used with STD or RC8 stacks.
2nd flies & shafts removed.
Leovince pipes.
O2 sensors turned off.
EPC turned off.
Rev limiter 9750rpm
SAS Removed
Make in Brisbane Australia, sea level, 22 degrees C, 95 RON BP Fuel, mapped to 13:2.1using a AT-300 auto tune

Thanks. Any toughts about the k&n air filter insert? Does it require a fine tuned mapping from the dyno or will this suffice? Can't seem to find any information about the insert and it's mapping anywhere.

It's basically a standard filter so it won't make much of a difference.

So I have been reading around in this post since I'm wanting to change my mapping and am not sure what mapping to pick. Have read a bit (but not the last 100 pages) but havent found my setup so far, so does anyone have a reccomendation for me?
I have:
Leo cans with DB killers in
SAS is NOT removed
standard airbox
2cond flies not removed

I want to open the flies and disable EPC and O2 sensor.
EDIT: I'm from europe, euro 95/98 fuel used mostly

Will be my first time using tuneecu, allthough I have a mate willing to assist that has used it before.
So any generic advise is welcome as well :D ;)
Thx
