Adjusting your EFI's / CO settings on the Super Tenere

[~TABASCO~]

This has been popular and widely talked about with the Yamaha FJR's for years. Has anyone messed with the dash buttons and looked to see if we could get into the CO mode? This IS NOT instructions for the Super Tenere but for the FJR.. But gives you the details on what was done and what do look for. Great for adding a bit more fuel, Etc... http://www.g-mac.net/fjr1300/gen_2_fjr1300_bjm.pdf
A little more about it... http://www.fjr1300.info/howto/co_adjustment.html Richen up the map a little.... Didnt know if anyone had tried this, or looked into it for some guys with pipes, Etc. that dont get the PC-V............ Just a thought...

This is the procedure for the XT660 and is identical for the XT1200Z.

It is in German, if I have some time and you guys are interested I will translate it to English, just let me know:

Hier nun die Anleitung zur Erhöhung des CO-Wertes und somit eines fetteren Gemisches bei der Dicken. Ist ein alter Trick aus meinen XT660X Zeiten und funktioniert auch bei der Großen.
• Zündschlüssel rein
• Beide Knöpfe am Tacho drücken und gedrückt halten
• Zündung an, dabei Knöpfe gedrückt lassen
• Knöpfe solange halten bis in der Anzeige „diag“ erscheint
• Um zur Einstellung des „co“ Wertes zu kommen, linken oder rechten Knopf betätigen
• Wenn „co“ in der Anzeige erschienen ist, wieder beide Knöpfe für ein paar Sekunden gedrückt halten
• Nun habt ihr ganz rechts unten die Anzeige „C:01“, also Zylinder 1
• Jetzt wieder beide Knöpfe drücken
• Links neben „C:01“ erscheint nun eine Zahl, die solltet ihr euch merken!
• Mit dem linken bzw. rechten Knopf könnt ihr nun den Wert für Zylinder 1 ändern, höher fetter, runter magerer
• Wenn ihr fertig seid, beide Knöpfe kurz drücken, jetzt steht rechts nur noch „C:01“
• Mit dem rechten oder linken Knopf wechselt ihr zu „C:02“
• Wieder beide Knöpfe länger gedrückt halten, bist links der Wert erscheint
• Gleichen Wert wie bei „C:01“ einstellen
• Zündung aus, und fertig

Um den Werkszustand wieder herzustellen, einfach den alten Wert wieder einstellen. Mein Ausgangsert lag bei „0“ und ich bin jetzt bei „10“.

Here are the instructions to increase the CO value and thus a richer mixture in thickness. Is an old trick from my work and even at times XT660X the Great.
• Key purely
• Press Both buttons at the speedometer and hold
• Ignition on, it can be pressed buttons
• Buttons in the display while keeping up "diag" appears
• In order to come to the setting of the "co" value press, left or right button
• When "co" appeared on the screen, press both buttons again for a few seconds
• Now you have the far right below the display "C: 01", ie one cylinder
• Now press both buttons again
• To the left "C: 01" appears a number that ye should remember!
Can • Use the left and right button you now change the value for cylinders 1, higher fat, lean down
• When you are finished, press both buttons briefly, right now is just "C: 01"
• Use the right or left button you'll switch to "C: 02"
• Again, both buttons held longer are on the left shows the value
• Same value as in "C: 01" Set
• ignition off, and finished

To restore the factory settings, simply set the old value again. My Ausgangsert was "0" and I'm now at "10"

Awesome ! ! ! Good job !

Section 3-10, 3-11 of the 2010 service manual describes the procedure.

Does this make any noticeable difference? I hear of the occasionally power dip at certain RPM? ???

Just noticed this, but maybe this topic should under technical rather than modifications. :

 

[Blue_eyes]

In the German topic they report that the dip is slightly less noticable when the CO values are set to 10 instead of 0 (their default value = 0 ).

 

[~TABASCO~]

Do you have yours turned to ten with your PC-V ?

Interesting. I guess it's very small change between 1 and 10 then as far as fuel adjustment goes. Any reports on fuel economy blue eyes?
Sorry for all the questions, just trying to understand what this adjustment does. Maybe it's just an idle mixture adjustment. I would think the 02 sensor would kick in to re adjust fuel delivery during normal driving. 8)

No I have not fiddled with the CO2 settings. No reason to do so since the PC V does this much more sophisticated.

Fuel economy you say..... I drive my bikes for fun, not to save money on fuel, I'm Dutch but not that much!

Just so you know: 1 liter of petrol here costs EURO 1.75 which is US$ 2.53 per liter, 1 gallon = 3.78541179 liters, so 1 gallon costs US$ 9,58 here in The Netherlands....

And you don't hear me asking questions on fuel economy... so who is skimpy here.....? ) ) )

 

[~TABASCO~]

Cost you about $60 US to fill your bike...... WOW ???

 

[Blue_eyes]

The ST Explorer Edition costs EURO 18,999.- here in The Netherlands, that's US$ 27,548.- :'(

You guys are lucky motherfuckers (excusez le mot) ) ) )

Let's just say we are lucky...................

According to Yamaha the CO settings are there for the idling only.

Just lucky?? I think it's mostly that we haven't yet allowed our government to fleece us on fuel taxes any worse than they already do.

I monkeyed around with the CO thing on my '03 FJR and can't say that it helped much, if at all. I didn't bother on the '06 and it runs just fine to this day.

I doubt I'll screw around with it on the S10. I don't care too much about fuel mileage but neither do I want the thing running too rich and/or causing other problems. And good fuel range on an adv bike seems like a good thing.
