Anyone changed the CO settings?

[Racing Snake]

Just done mine . Was on 0 so whacked it up to 10 .

Don't know what is the optimum but will give it a try.

Welcome to the Forum! Where are you located, what color SuperT do you have? Post some pics!!!

 

[Racing Snake]

Thanks.

Im in Leicestershire in the UK.

Ive posted a pic in the media section.

Let us know if you feel or notice any change you might feel.... 'thumbs up'

Went for about a 30 mile ride and yes think it rides better especially since I now have a full system on the bike. It still has a flat spot at 4500 rpm but not as noticeable.

Cool... if you think about it, let us know if you notice any difference with your fuel economy...

What full system do you have... do you have Arrow headers ?

the TDM900 lads have been tweaking the CO settings for quite a while.

Below is a quick overview of how it is done on the TDMs.

My view is that it helps a little at low revs when throttling on with a small throttle opening , anything other than that is a placebo effect.

From Carpe-TDM.net forum

REGULATION OF THE AIR VOLUME OF THE EXHAUST GASES

NOTE: To set the density of carbon monoxide (CO) in the exhaust gas.
(translated into common tuning terms, this means that you are adjusting the fuel injection to increase or decrease the amount of fuel delivered. Marc)


Procedure
To activate modes "CO" and "DIAG":
Press together the "SELECT" and "RESET" keys, and turn the ignition switch on "ON".
(NOTE: It takes ~eight seconds after turning on the ignition switch - until "DIAG" appears on the dash display.)
In order to get to the "CO" mode: (so you can adjust fuel delivery)
Push "SELECT" in order to toggle the display between the "DIAG" mode to the "CO" mode, and vice versa.
Push together the "SELECT" and "RESET" keys for two seconds and the word "C1" should appear on the display.
(On the 900, C1 means the left side cylinder 1)
In order to select the cylinder to tune:
Press "SELECT" or "RESET" in order to select the cylinder (C1 or C2). Toggle between each to select the cylinder required.
When the required cylinder number is showing on the display ("C1" or "C2") -
Press together the "SELECT" and "RESET" keys for two seconds and the current value for the selected cylinder will be displayed (eg. "9").
Write down current values for each cylinder so you know where you started !!
To change the volume of carbon monoxide in the exhaust gas: (translate: to adjust fuel for best running and best power....)
On the display is shown a figure between -128 and 128 where -128 is very lean and 128 is very rich.
Press "RESET" button in order to lower the numerical value and decrease the amount of fuel delivered to LEAN the mixture.
Press "SELECT" in order to increase the numeric value and increase the amount of fuel delivererd / RICHEN the mixture.
Press together the "SELECT' and " RESET" keys in order to return to the selected cylinder number ("C1" or "C2"),
and go back to 3 to tune the other cylinder.
To SAVE the settings, turn "OFF" the ignition switch.
Now - all that being said.... Additional Key points -
When you are pushing buttons and increasing or decreasing the C1 or C2 numbers, you can hear the engine change exhaust note, showing that he fuel delivery is changing as your are changing the number values.
That's called "REALTIME" fuel changes.

If you have a dyno like an EC997, you can watch the engine power smoothness (Flux Value) change as you change the fuel rates at "cruise" throttle and rpm levels.

The better you have the mixture, the smoother the engine will be. (but we all knew that).

Also - the 900 uses c1 for the cylinder 1 (left) and c2 for cylinder 2 (right).
That's not necessarily true for other Yamaha's. The "kit" 600 and 1000 ECU's have tuning "ranges", based on throttle positions and rpms.

The street Yamaha's, R6, R1, Warrior all tune similarly to this, but you need to know the "secret" handshake to get into "CO" mode......

Hope that helps

Ill report back on the fuel economy.


Yep , Arrow headers and a Remus Titanium can .


Couldn't believe how heavy the OEM can was when i lifted it off. :-[

Heavy can: no kidding, most stockers are.... The ones off the Yamaha Stratoliner (single) and the one's off the FJR's are crazy heavy.... I think they add 20 Lbs of lead for ballast ! !

Where did you get your Arrow header? Do you have a link? Prolly going to build my own but want to take a look.... Thanks !

 

[Racing Snake]

Got them from here.

Bit of a trek from texas !

 

[Racing Snake]

Rode to Fairford (USAF base here in the UK) today to watch some pre airshow practice and the computer was showing 50mpg at 80 and 46 at a steady 90. Pretty impressive.

Mind you the engine has done 1200 miles now since new and has loosened up considerably ..

 

[HoebSTer]

what will increasing the CO# do on this bike? Does it make it richer or something?

Thats correct but only for the idling .

 

[Swagger]

That Arrow set up is looking more and more appealing to me at the moment. If you stuck a PCV on it surely that would sort any issues with fuelling wouldn't it.

Yes Im sure it will and that is my next mod for me to buy.

One think is though ,as the engine loosens up with the miles it gets smoother and the flat spot is a lot less noticeable 8)

I just did mine also. It was 0 and I changed it to -50 less gas is better for me )

mine was already running extremely rich 16 L/100km I don't know why but may be bad fuel?

16 L/100 km that is only 15 miles to the gallon. That’s the same as my Tundra..

I know isn't that crazy....I must have gotten bad fuel. It happened to me before but went back to normal.. This time its taking longer about tank and 1/2 still running rich

 

[SpeedStar]

Anybody else try this adjustment yet? I am wondering if it could help the slight stumble I have with first gear starts.

 

[SpeedStar]

I tried to make this adjustment on my California model XT and appears that it is not possible. Following the directions, I have it off, hold both select buttons in while turning ignition on and continue to hold the buttons for 8 seconds. It then shows diagnostic mode. Next we should be able to press the left select button to toggle to diag or CO mode. Mine does not toggle.

Do the other US bikes have the feature and only us lucky CA model bikes not have it?
