Would I be in the ball park of the truth here Kevin?

Your device would have little effect on tyre wear since it is really only relevant until 20% throttle. Rear tyre wear would be due to larger throttle openings than that.

But if you spend a lot of time commuting in the 0-20% throttle zone, could it be kinder to chain, sprockets, gearbox, cush-drives and other stuff; maybe even the engine? I found I used to ride the clutch an lot when scooting through traffic, just to smooth and settle the bike. Hopefully that's all behind me now.
The biggest thing when changing the A/F ratio to 13.6:1 in the closed loop is it allows for less hand movement throttle & clutch as it is easier to keep the bike cruising you are not fighting the fuel injection as much especially in the sport mod, with less on/off throttle movement there would be less on/off load on the chain & sprockets. I have never really thought about it but I would think it might make a marginal difference in chain & sprocket life, but there again you have a hooligan bike that loves to be revved & ridden hard.

This 690 motor does have quite a bit of drive line shunt when the motor is lugged around at low RPM's due it's crank to clutch & final drive ratios this is a Characteristics of it's design which we can only change the final drive sprocket ratio, I do think the bike is over geared & would go one tooth down on the front sprocket if I owned one. As for the fuelling it is just to lean in the open & closed loop maps for emission control like every other new bike out there, with the single cylinders & V twin motors showing the worst side affects of the lean A/f ratio's.

I am sure I will have more to say on Kevin's mod as I spend more time on the bike.

In short it is big bang for buck.

The roll on is much nicer. I have returned to the sports mode because the throttle control is appreciably smoother, but still has a very explosive feel about it. It feels like a well calibrated weapon, precise and sharp. It is quite user friendly all the way down to 3'000 rpm and I have my cogs geared up so the engine is more loaded on my bike at 3'000. If I geared down, as Kevin suggests he would do if he had a Duke, first gear would be pointless.

What are the specs on the bike you developed this on Kevin? Without specialised mapping, which I hope you will help me with down the track, my engine is about as highly specced as is possible. I think that with the extra punch from the cam etc, taller gearing is the way to go. I found that the bike settled a lot when I went from 40 teeth on the rear to 38.

The exhaust blows damp into my hand on idle, so I am pretty sure the bottom end of the rev range is nice and rich.

I cannot say yet if this will make me more or less responsible on the road. Yes - it ambles along like a well behaved commuter if you want it to. But because you can run it very nicely in sports mode, all that extra grunt is there to exit roundabouts in style.

The biggest excitement for me, besides how well it behaves, is being about to feel the tyre bite as you open the throttle. The roll-on shudder before the mod used to make it difficult to feel the rear tyre bite.

Thanks Kevin, very happy. More to come in time.

the the device made him a "better" rider, calming his riding style, I know what he means. Instead of accelerating and braking constantly! the bike now feels happy to glide along a sensible speed
Blasphemy !

Actually now your bike may be sad. Crying in the garage. Slowly dying inside.
It will develop an identity crisis and turn into a Honda scooter.
Go wheelie it immediately to start treatment.

Boldor thanks for taking the time in giving us some feedback on the O2 Controller mod.

The bike I used is a 2013 690 Duke with Akra pipe with Standard mapping, the owner contacted me asking for help he wanted to ride in sport mod all the time but the surging was getting on his nerves, his 690 is running my fuel mod as well so we were able in increase the fuelling a little in the open loop which also helps with on/off/on throttle response & roll on's. Running the O2 controller by it's self does make the 690 nicer to ride. I will let you know when the fuel mods are ready & I will send you one to try.

Once Alan is able to get into the Can Bus side of things in these ECU's I will develop some maps on the Dyno using Tune ECU, so until then we have very options to tune these bikes.

If there is anyone in Brisbane who wants to try one you are welcome to pop over to my house & we can fit one for a test run so you can feel the difference.

I have family in Ballina who are screaming out for a visit from me Kevin. Would my bike be of any use to you in person?
Thanks for the offer we are all good at this time, all the development has been done, I have been able to work out what the 690 ECU wants to see in the closed loop circuit to correct the A/F ratio to obtain the smoother ride.

It would be nice for the guys in Brisbane to pop around to see if the mod is what they are looking for. I like to make my mods plug & play so no cutting of wires, if you like it buy one & you can leave smiling. SO an offer of try before buying.:santa:

Very interesting stuff Kevxtx!! I am interested in this mod.

I am a new 1 month old 2013 Duke owner and I love the bike. With just more power and better sound it will be perfect. The most noticeable thing I found on this is the jerkiness at lower rpm constant throttle position. I am very used to this since I have an 2008 Tuono which is much worse than the Duke but it would be nice to correct both both. Do you have the O2 control for a 2008 Tuono?
How does your dollar convert to usd? Any idea shipping cost to the US?
Keep us posted on the Duke fuel mod.

Baldor, any more testing done?

My O2 controller mod works on the Aprilia's DD750 & 1200 + the 750 Shiver, not tested it on the Tuono.

As every bike has a different setting in the controller I would need to use my Master Adjustable O2 controller + wideband commander to measure the A'F ratio in the closed loop while riding, I adjust the controller until I get the desired A/F ratio in the closed loop then build the mod to suite that model.

Do you know of anyone in Brisbane with that model bike & I will give it a go for you?

All my O2 controllers sell for Oz$105.00 + $25.00 registered international air mail postage. The US$ is stronger than the Oz$, Total = Approx at today exchange rate US$118.00 including postage.

Still raining Prime. Will post as I learn more about it. You'll be sick of hearing from me soon.

Would love to road test the fuel mod when you have one ready Kev.
I will send you one to test as soon as I get the connectors.

Is the install of the O2 control easy with instructions?

I have family in Australia, none with a Tuono and even if they did or knew someone it would not be much help. They are in Darwin and Perth. Can you all be any further apart?

If you don't mind, I am on the AF1 Aprilia forum and could ask there. Others there I am sure would be interested including other rotax powered bike owners.

Nope, keep it coming. I want to learn everything about it. I have not felt so good about a bike like this duke since my old RD350 I had back in the mid- 70's.

I wonder how this would work on a 2013 690 R :euro:
The mod will work on any 4 wire narrow band O2 sensor, I am sending one O2 controller to the UK for testing on a 2013 SMC this coming week using the D's spec's. The limitations of this mod is finding the bikes for me to test it on to get that magic number of 13.6:1 in the closed loop. As mentioned I do this as a hobby & if my mods can help guys out then I am happy, I had this mod running on my 990 SMR back at the beginning of 2011 when there was no tuning device those days.

The Yamaha XT660X have been running them since 2008 with a slightly different version that could actually turn off the closed loop circuit but found those take to long to make & the guys fitting them found it complicated to install the mod as it needed to be fitted to the cooling system as well as the ECU, these days I only sell the latest type plug & play.

The O2 control mod has evolved to generation 4, the first three as shown below could turn off the closed loop completely then force the ECU to only run on the Open Loop map only.



Now we have the latest 4 generation which came out last year that controls the O2 sensors square wave signal to the ECU, XT660 fuel & O2 controller mods shown below.

Woooooo-ooooo. Muchly Excitement.

Pressure is being piled on by me to get into the ignition system Kev. My trackie mate on his 2010 is still laughing at me. I can tell by the way his helmet wobbles from behind as he takes off down the straights.

And I have twice as many spark plugs as him!!

Do you still have the cat fitted, as the 690 got a Leovince link pipe fitted yesterday to the Akra can & has made a nice difference from 4000rpm & above.

Someone might want the whole system.

Has anyone tried DNA's filter out yet? http://www.dnafilters.com/en/news/product-news/212-new-dna-high-performance-air-filter-p-kt6sm13-01-for-the-ktm-690-duke-abs-2013.html

On my last XT660 a few years back which had a big bore + stage 2 cam I ran this air box.



The difference between the standard air box air flow & the stage 3 DNA air box.

My system is as follows.

Open box (from tuning kit) - K&N filter - up specced cam - stainless homemade bypass - Ti end pipe and Akraprovic silencer.

Presently using the Akraprovic map and your O2 mod. Stock front sprocket and 38 (stock = 40) rear sprocket.

I'd like a map for that system with the db-killer plug for the road, and one without for the track.

This sounds exactly like what I need. The bike is like Boldor said, cruising at low speeds, it is like an epileptic that has gone without medication for a long time.

Might order one from you later in July : )
