PCV and "lambda o2 sensor"?
 

Hi there,

I was using my PCV over a year now and I'm very happy with it. I bought it for my DNA stage 2 mod and the OTR 2in1 aftermarket can. On the PCV I loaded also the map from OTR for this very setup.

Today I was going through the OTR shop again and have seen a lambda O2 sensor eliminator. I wrote to OTR and asked Throsten if this is necessary for my setup as well and he tould me that it is, otherwise the PCV is not doing its job properly.

What is your opinion? Do I really have to eliminate the O2 sensor? And if so, where can I find it?

Thank you so much for your time and help.

Cheers!
Mike

Can you point me to a link on which O2 eliminator you are talking about?

If you are talking about the old type O2 eliminators, they don't work on any XT660 the A/F ratio is to unstable, the Dynojet O2 emulator & my 2010 O2 eliminator are the only 2 know O2 eliminators that work on all XT660's.

The XTZ has shown it can run well with a PCV/PCIII/Kev fuel mod with the O2 sensor connected, my O2 eliminator has been proven to show a better stable A/F ratio compared to not having it fitted with these types of fuel mods.

I have no idea if that's the new or the old type. What is A/F ratio? Air/Fuel ratio?

Thanks!

Old type, it does not work on any XT660's, this was proven back in 2009.

Ok, thank you for the clarification. Where can I get your 2010 O2 eliminator for my Ten? Would you recommend it to me?

PM sent.

I'm interesting too.
I take a look at Dyno website: for xt660x/r they say to use their O2 eliminatore, while for xt660z they say to use PCV with O2 sensor connected.

Do you think there are really advantage with your O2 eliminator? How work my PCV with O2 sensor connected?

Thank's

From data logging the XTZ A/F ratio the Z has a more stable A/F ratio with the O2 senor connected but it will run leaner in the closed loop circuit & give better fuel economy.

If you want HP & Torque all the time a O2 Eliminator has the best results.

I understand, I had the same intuition. But closed loop circuit work only between 3000 and 4000 rpm?
Only one question: if with O2 eliminator is possible to use PCV between 3000/4000 rpm, why Dyno website don't suggest their eliminator?
Can you ship your eliminator in Italy? How much it cost?
Thank's for all your support

The closed loop circuit actually runs between 2500 to 4500 rpm, right in the range that most of us ride all the time.

The X/R closed loop circuits have different parameters to the Z, with the X/R's closed loop circuit being more aggressive, so they have to run different settings in the Dyno Jet emulator so they advise disconnecting the O2 sensor until such time as they finish building the XTZ's emulator, with my mod it does not emulate the O2 signal it turns it off completely.

My O2 XTZ eliminator will be released very soon, I am just finalizing the installation notes & will announce them for sale in a week or 2.

The cost of my O2 Eliminator will be $75.00 including postage world wide, payment via Paypal.
