02 sensor
 

Hi,
I bought a 02 sensor from Kev for my XTX 08 model, well made bit of kit and worked fine on my bike.I then bought a 02 sensor box from Powertec and found that It did the same job as Kevs but in a differant way.XTs have had this surging problem for years and now we have a choice of two.Bit like buses none then two at the same time. http://www.xt660.com/images/icons/icon14.gif

.....And my O2 Sensor mod is brilliant.
XTra Smooth bike.:bunny:Easy peasey.

Brilliant
 

After reading this thread and with surging still a problem with my R 09 (even with a Power Commander V fitted) I decided to buy the new mod.
The package arrived safe and sound in the post exactly 8 days later and it was very easy to fit thanks to the detailed instructions provided. After a few PM's to Kev I managed to load the map provided by Kev and I must disclose the the bike is running SWEET now!! I would say the the surging has been reduced by about 95%. I will still buy the Autotune module and I have confidence that once this is installed that my problems will be over at last.
A BIG thank you to everyone who contributed to this fantastic mod and especially to Kev for his patience in answering all my questions.
If you have the same problems with surging I would say BUY THE MOD! You won't be dissapointed.

Thats great to hear, I also bought this mod and will be getting myself a PC3 next week, so I'll keep you posted how my xt-x 08 will behave once these mods are fitted.

I have just been for a good blast on my X and i am now getting more MPG from the bike with this mod and fuel map than i was with my old O2 eliminator and map so very happy (15 miles more than normal until the fuel light came on from a full tank)

You will get better mileage with my new O2 mod compared to the old Dynojet one, because with the old Dynojet O2 eliminator it could not fully control the closed loop circuit & ran rich then lean all the time with a unstable A/F ratio.

With my new O2 mod your A/F ratio is completely stable & can be mapped correctly over the whole rev range, unlike the old Dynojet O2 eliminator.

I still have the old type of O2 eliminator and a PC5.

Havent put it on the bike yet, the weather is becoming better so I'll be doing that now.

Haven't been to this forum for a while so this is big news for me.:038:
Have to start collecting � to buy this.

Im going to dyno in a couple of weeks for a custom map so I suppose, when I buy the new eliminator, i will have to re-dyno it?

Don't waist your money going for a custom map if you dont have the New Dynojet controller or my New O2 eliminator. The old O2 eliminator does not keep the A/F ratio stable.

Ok, the custom map isn't stable, this I understand. But is it better than the zero map that is on the PC when it is new?
Building a custom map doesn't cost too much here.

And another question. I already have a blanking plug, the O2 sensor is removed. What would I do with the old eliminator, when I decide to buy yours? Can it stay there or do I just remove it, too?

As my new O2 mod completely turns off the O2 sensor, the O2 sensor can be removed or left in. Throw your old O2 eliminator in the bin.

You might as well install one of the custom fuel maps in the ASK KEV section, which is close to your setup & mods until you can afford to buy a New O2 Eliminator or Controller, then do the custom map on the dyno.

A custom made fuel map should cost double the price of my O2 Eliminator.
