Does it really matter? Having bought it second hand I got no paperwork with mine so I just plugged it in. Is there any setting up needed that you require the led for?

Plug & play & way you go, the O2 controller remaps the closed loop circuit in real time.

OEM bike with the Kev Mods
 

Just wanted to let folks who have the OEM exhausts and Air filtration know that the KEV MODS mentioned in this thread work wonders even without changing anything else on the bike.

After putting both magical boxes on the bike, I took it out for a 230 km ride and noticed that the bike's throttle response was smooth at all RPMs. I hit the rev limiter a couple of times because the bike was running so sweetly in the 6k RPM range!

And in first gear, running along single track trails, the engine response to throttle inputs is SMOOTH.... No more "herky-jerky" while crawling around rocks!

I know, I know, everyone has said it before, but these mods make the bike so much more pleasant to ride. Thanks much for the great products, KEV!

fitted the 02 mod

Thanks for your feedback.:068:

o2 controller + fuel mode done
just got a new set of twin akra.
what time shuld i set the clock to?
thanks.

Feel free to download the mod instructions off my Ebay ad> http://www.ebay.com.au/sch/7416kevxtx/m.html?item=141644263870&ssPageName=STRK%3AMESELX% 3AIT&rt=nc&_trksid=p2047675.l2562

O2 mod on Tenere
 

Was a bit sceptical as the Tenere runs pretty well but went ahead and bought the O2 mod.

Turned up pretty quickly and really simple to fit, used some double sided tape to stick the unit underside the tank.

Result. It's one of those changes that is quite subtle but once you realise the change you really really appreciate it. So whereas the bike had nothing under 3k revs and demanded a downshift it now pulls smoothly from down to somewhere nearer 2k revs. Saves lots of shifting and makes off roading or slow speed manouvering much much better, the bike doesn't feel over geared down low.

Recommended.

Thanks for your feedback, running the closed loop richer improves the torque in the lower RPM which make the bike respond better & ride smoother.

If any forum members are looking for Fuel + O2 controller or the Controller & Fuel mods separately send me a PM & we can have a chat.

O2 controller
 

Just fitted on my new Tenere, only 200 km on the odo. Five minutes to install and it was an easy job: I used only fingers as my torch decided to die.
It takes me some minutes to catch the difference but once I realize I changed the drive style.
The Ten runs smooth on all the rev range, there is more torque at low revs. I dont have to shift down gear as much as before, the engine is smooth even under 3k revs.
Now its another bike, really fun to ride.

Definetly a "must" mod, thank you Kev

Bummer
 

Finally decided to buy one of these O2 controllers. Out of stock:cussing:This was the message which came up on Ebay when I tried to make the purchase

Who said they are out of stock I have plenty in stock ready to post next business day?

If you just want a fuel mod: http://www.xt660.com/site/node/136

HAHA Kev perhaps the people who ripped it from us in the first place and are selling them on the black market with your name and copyright breach have run out of stock.

One can only feel sorry for them. :no[1]:

Hello guys!

First post after lots of reading =)

So I wanna put a Kev Mod on my Z, '08 model.
I found that on ebay : http://www.ebay.com/itm/142122627389

I guess I should fit both fuel mod and 02 controller for best results.

BUT....

It's written once
And after
As I said, I've a '08 model. Does it fit or not ? :icon_scratch:

Hi

can we use a mod to the coolant sensor and keep the engine in open loop?

thanks

Kev's version 1 device did take into account coolant temperature and was quite complex to install; one of the reasons he stopped making it. It is now superseded by the current 'plug-and-play' version.

Read this: http://www.xt660.com/showthread.php?t=14746

Yes it will.

OK thanks Pleiades.

I need some help...

I am trying to catch a signal from the o2 sensor with an oscilloscope.
I probe the grey cable on the ECU plug but I get strange signal. Is this the right cable?

I am working on a mod to keep the ECU in open loop and I want to check the AFR (not AFR but lean or reach) by probing the o2 sensor.

Thanks

On the ECU side of the loom:

Grey = signal (ground)
Grey with green trace = signal (+)

On the O2 sensor side:

White = signal (ground)
Blue = signal (+)

thank you very much Pleiades.

I have a question...

Do you think that we should use a CR6E spark plug for these mods?

thanks

Every variation of fuelling setup I have tried, both with PCV and Kev's mod, has worked perfectly well with a spark plug of the stock recommended heat range (7). I see no reason to go to a hotter (6) or a cooler (8) unless you've radically altered the motor, the fuel used is of poor quality, you're over/under fuelling and/or you're bike isn't running right in the first place. Even if you do feel like trying something different/fancy, it's always best to start with a stock copper core #7 plug to get yourself a baseline from which to work.

ok thanks, but why copper core? I thought the iridium would be better...
