Buy one and find out: Simples!

Not at all it is a O2 eliminator, which connects to the cooling system that turns off the O2 sensor closed loop circuit on a XT660X/R, when the cooling system reaches 100C the mod turns off & allow the ECU to see the correct water temp so the fan can run at the correct time.

This is my current fuel map that was built for good fuel economy manly for work & back. This map is on my 2009 XTX with a 11 ECU & my NEW O2 mod.

As you can see the A/F ratio is very stable, mapped using a Power Commander.

This is same bike with the exact same mods but without my O2 mod, the A/F ratio can't be mapped using a Power Commander.

very good evidence !!! smooth as silk!!!!

O2 mod and Staintune SFI
 

Hi Kev,

Do you think a Staintune SFI can work with your mod? I've got an 08 xtx with a 11 ecu, stage 1, 2 air filters and 2 in 1 exhaust. The surging while commuting is absolutely unacceptable and stumbling across this new mod development is rather exciting to say the least...

Thanks for you advice and all the persistent work on improvements mate.

No worries.

It should work, you would need to play a bit with the SIF to find a happy medium, I can advise on the settings where you need to set the SIF I would be keen to hear your results.

If you are not happy with the results send the mod back & I will give you back your money less postage.

They can be bought from here.

You have my order for one, Kev.:clap:

Thanks Mate!

Thanks mate just boxed up your mod ready for posting first thing in the morning, in 12 hours time it will be on it's way to you.

The mod has received hardly any response, so not sure how long I will be making them, we will see over the next few months how the mod goes. I still have my O2 mod on my bike & have not put the 06 ECU back on, it goes just fine with the O2 mod on the 09 (11) ECU.

I'm sorry to hear that. I have been waiting for spring but I've also been hoping to find a cheap PC3 before I order, since I can't use this mod without one.

Please give a heads up before you stop making them, and I will most certainly buy one then at the latest.

I found this:

What do you think Kev, can that be used instead of a PC3?

EDIT: I did now find a few posts saying it's basically a variable resistor to richen/lean across the rev range. (a'la Kev fuel mod I presume?)
In other words it will not do the job for this.
