Yip & they work as designed in controlling the A/F ratio.

Give it a go you are an engineer, I worked out my O2 Controller 6 months before Dyno Jet brought theirs to market, here is a little show & tell of a competitors O2 controller I am sure you can work it out from here.

I have been making these mods for many years now & have never had any problems, my local Yamaha dealer endorse these O2 controller for KTM & Yamaha, I am a qualified motorcycle mechanic with over 3 decades of experience, every mod is Dyno tested so I know 100% what the O2 controllers are doing...

I wish I had $1.00 for every person who has asked me that question, it took me a long time to work this problem out controlling the O2 sensor voltage signal & many hours of Dyno time, I have spent many $ of my own money to perfect the final product, I have already worked a way out of controlling...

If we really get into the technical side of the sensor voltage wave evaluation I would have to say you are correct, it is not a perfect square wave form signal. The O2 sensor generates it's own voltage wave forms when we start to see a O2 sensor generated voltage it spikes up, the voltage (as...

PM me when you are ready, pop around to my house if you want & I will fit one for you to try.

I have not heard from Reece for a while now, does he still have his 990SMR, I did a bit of work on it for him. To answer your question the O2 controller adjusts the offset based of the sensor output constantly, the OEM O2 sensor generates it own voltage signal from the unburnt oxygen, this...

As you say to make the install easier for everyone. Updated O2 controller instructions http://www.4shared.com/download/oH8Wazw_ba/Update_Kevxtx_MT_FZ_09_instruc.pdf?lgfp=3000

I will all this photo to the instructions for you.

Thanks for your feedback I will have a look at the fitting instructions to see if I can make the removal of the OEM connector from the bracket clearer, let us know what you think when you have ridden the bike a bit more.

Usually a week & a bit to the UK & USA, for some reason Europe takes a bit longer, when they are late it is usually been held up in customs & can depend on your local postal speedy deliveries.

Thanks mate.

Thanks for all the feedback guys.

Hahahahahah:D

Thanks for your feedback, richening up that closed loop does make the bike much nicer to ride

The bike is looking great mate.

Co setting set to zero with the O2 controller.

Fare comment & would agree 100% point well taken.

Sorry mate, I will be hush from now on, I was just sharing what goes on in my biking life, I have deleted my last post on my KTM Dyno stack mods but the KTM results do directly reflect what I have in mind for the 09 as in air boxes & stack testing. Just to set the record straight this O2...

I no I have a bad addiction & will seek help one day, modifying things is my addiction. :cool:
