2012> 690 Duke

My O2 controller mod might help a few of you guys out with that part throttle surging, I just really want to know if anyone is interested in these mods, if there is interest I will make them for you guys. A friend contacted me & ask can I make his new 690 run smoother around town & that is how this mod had come to the market.

The O2 controller mod will help with the surging in all map modes, it is designed to be fitted with free flow systems.

You can read about them from the Yamaha boys, http://www.ebay.com.au/itm/130930901328?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649

I make these controllers for.
Yamaha's
Kawasaki's
Aprilia's
And now 2012 onwards O2 controller mods for 690 Duke KTM's, adjustable fuel mod on the way just waiting for the OEM connectors.

It is plug & play no cutting of any wires, the mod is 100% waterproof.

I have been making them for a few years now for other model motorcycles & was approached by a friend complaining about the surging on the sport map on his 2013 690 duke, so the 690
O2 controller mod is born. As mentioned in my SMT forum post this is not a resistor mod it is a device that controls the output signal to the ECU in a square wave pattern.

I have stock of the mods & am ready to ship if anyone want to try one out, the mod is designed to control the surging at part throttle openings when cruising.

The price is Australian AUD$130.00 shipped world wide registered air mail post. I can be trusted 100% I have been an administrator of www.XT660.com forum the past 8 years & runs the www.ktmsmt.com forum as well & have a long standing credit in the biking community.

Payment via PayPal, posted next business day, if I see a demand for the mod I will make more & post them on EBay.:scooter: If you want one Pm me your PayPal details & I will send you an invoice.

Cheers
Kev

Nice one, Kev.

While this mod surely would come in handy for those without any other option for tuning eg. TuneECU it would also help if keeping O2 enabled for everyone.
Are we talking about stable throttle hunting/surging, or jumpy/twitchy throttle openings here or both?
Cause most of the jumpiness could be mitigated by either a throttle tamer or even editing the throttle profile behavior by software. I also gathered that reducing high F-L switch values that determines the switchover between 'Full' & 'Low' fuel maps helps to smooth out the bike. But all this should not directly address the closed loop process, don´t you think, which is completely separate?

Also have you found that the O2 controller would help cooling things off a bit since the bike temperatures are increasing quite fast when stuck in heavy traffic?

So since I think the are still some stable throttle surging left I could either go for your O2 controller or just switch the darn thingy off in TuneECU? I like to leave it on so it is adjusting A/F ratio a bit, even off idle load, or is this really pointless if the cat is removed?

The A/F ratio in the closed loop is kept at 14.7:1 my O2 controller keeps the closed loop A/F ratio around 13.6:1 the transition between open & closed loop maps is closed so reduces the twitchyness, the O2 controller helps with on/off throttle openings + the surging at steady throttle openings.

At the moment there is no tuning option with Tune ECU for 2012 > 690's, I do have an adjustable fuel mod for the 690 I am just waiting on the OEM connectors, the fuel mod will adjust both F & L maps in the open loop.

One advantage the O2 controller has over turning off the O2 sensor is the controller still offers better fuel economy than the sensor been turned off.

I am fully converse with Tune ECU & Tunelink Dyno programming software, I have built most of these maps for the SMT/SMR boys. http://www.ktmsmt.com/viewtopic.php?f=13&t=3770

Those of you technical enough & who regularly use the advanced map, this sounds like a good mod. I'm not sure it will be something I'll try any time soon, but what I can say is this: I've followed Kev on another forum, & his knowledge, expertise & general helpfulness are second to none - top bloke!

Recommended 100%!!!!!!!!!!!:thumbup:

I am having trouble comprehending the lack of interest here riders.

There are only two faults with our Gen4 Dukes (cannot comment on the others):

1. It won't go over 200km/h.
2. It stutters and shakes like an epileptic who's lost his medication if you ask it to coast along at a docile speed. (We know your solution Wiwwee).

If this mod achieves half its claims, expect me back here ranting.

Then I'll just need to work out how to get another 30 hp and I WILL have the perfect bike.

I agree with Boldor, weird that this mod didn't catch more attention.
I know Fred is interested as well, but want's to hear my opinion before he orders it. :)

Still early days, at this stage I just want to see if you guys want this kind of mod for your bikes if the mod is no popular the mod will die off, as mentioned I have a basic adjustable fuel mod that can adjust the A/F ratio in the open loop mapping that will complement this mod, I am just waiting for the OEM connectors to arrive from the USA. There are a few 690sd's already running this mod in Australia, I made 100% sure this O2 controller mod worked on the 690 Duke before releasing the mod. I have full access to a Dyno & am a qualified motorcycle mechanic & test every mod I produce on the Dyno.

It is very easy to see how much it changes the fuelling, ride the bike with the O2 sensor connected, stop turn key off fit mod between the O2 sensor & ECU key on ride the bike again, stop the bike again & remove the mod & ride the bike again. Just a reminder this mod is for improving part throttle cruising it increases the fuelling in the closed loop map circuit.

Sounds very good, if this one is a big improvement, then I'll definitely look at the open loop system as well!
I think the bike is running a bit too lean at the moment. However, with the adjustable one I guess I'd need to dyno it to set it up properly?

My week is over. I have the O2 controller in my hand. I am going to pour a Scotch and head down to my garage and fit my new toy. It has been raining here incessantly and I have a mild flu. So don't hold your breath on a feed back report. Hopefully before the w/end is done.

Fcuk off rain.

No - it did not work. Still raining.

I am such a child. Despite having hung my bike up to fiddle, fit the 02 sensor and clean it reasonably thoroughly, I had to go out in the wet for a run. It was dark and damp and I stayed of the main roads, so it was hardly an ideal road-test: But I could feel the difference.

Anti pollution stuff has a lot to answer for.

On Kevin's Ebay website there are comments from those who have fitted the same device to different makes and models of bikes to our Dukes, work Kevin has done earlier. One comment said 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, excellent for traffic and commuting.

If you ride more calmly, aren't you less likely to use up fuel? Does fitting anti-pollution devices increase your fuel consumption over the life of the bike by making you ride more aggressively?

Thanks for your short ride report, your comments are spot on that is the area the closed loop leans the A/F ratio out & the O2 controller corrects the signal.

I can answer your question to does the O2 controller use more fuel & the answer is it should not as you now have more torque available with the corrected A/F ratio, with a closed A/F ratio of 14.7:1 it is far from an ideal A/F ratio, at 14.7:1 you burn up most of the hydro carbons to keep the Greenies happy but at a cost of engine performance & fuel consumption.

An A/F ratio of 14.7:1 produces less torque than a A/F ratio of 13.6:1 which is the target value the O2 Controller aims for, more torque means less throttle opening at the same cruising speed.

I never promote any of my mods I let the riders give their honest aspects & views on the mods, most are good the odd one is questionable I will leave the judgment up to you guys. I make these mods as a hobby trying to find ways to improve fuel injections, the difference I have a Dyno at my disposal & can test any mod I want with before & after runs.

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.
