I am looking to buy the FI tool for my WR so I can adjust the CO2 but I am having some problems finding it. I found this on Amazon but cannot find anything to indicate if this works for my bike.

 

http://www.amazon.co...623860_70668670

 

 

Anyone have an idea if this is the correct tool?

That looks right. I think there is only one.

I purchased the Yamaha branded FI diagnostic tool from http://www.cmsnl.com...2/#.VdZOpniBMUV

 

Current price 88 Euros = $99.00 and my shipping was about $15

 

So considerably less expensive than the Amazon seller

The link  is for the GTYR tuner, is there a way to adjust the CO2 at idle with it?

The GYTR tuner is for adjusting the fuel and ignition maps, not for setting CO [carbon monoxide not carbon dioxide] levels. 

 

Tuner functions explained pretty well here : https://www.rockymou...YTR-Power-Tuner

That's what I thought, have used the GYTR. I went ahead and ordered one from CMSNL, do you remember how long it took for yours to get to you?

So, that diagnostic tool comes with a widband CO sensor ?

It doesn't measure CO, just adjusts it.  It's good for adjusting the TPS too.

How can you adjust it without measuring it ?

It took about a week to receive from Europe

Maybe adjust is the wrong word.  You can change it.  I set it to lean best idle.  If you're shooting for a particular CO output maybe a garage would let you use their exhaust gas analyzer.

Tool came in today, I'm impressed with how quickly it got here from the Netherlands. What are you guys running yours at? Or maybe what the ideal percentage is? I have access to a sniffer so I can play with it a bit.

I've got it at -5 currently.  For a car, it looks like CO should be less than 2% with a stoichiometric idle.  Others on here suggested 3% CO, I think.  For me, a rich idle on a fuel injected bike is just a waste of fuel.

 

There's data here from a couple bikes.  They're probably all a little different.

Just so I am understanding correctly, when you increase (+) the number on the tool it is increasing fuel and going minus (-) is decreasing...?

Yeah.  I think most people get better electric start with a positive number.  I have to pull the knob for a cold start but I think that's how it's supposed to be.

 

I have different cams in there, maybe it pulls less vacuum at idle and uses a little less fuel?

I'm going to by the FI tool to set properly the CO. I understood that it can also check and set the TPS in case of problems .
My question is: can it be used also for reading errors (better understanding malfunctions), or other service functions or its use is only for setting CO and TPS?
Last questions is if it is a really standard tool for the other yamaha (for example can I use it to set CO also on a super ten?
Thanks a lot to everyone!

Hi Paolo

Yes the diagnostic tool can be used to check fault codes, I can't see why you couldn't use it on a super tenere, I have seen one used on a 660 tenere to adjust the CO.

For those that bought the FI tool from cmsnl, does it come with the right connectors for the wr?
Thanks
