Changing the CO settings in the DIAG menu

[Triple Trouble]

TT - did you or your dealer change the CO settings when you put your S1R on? If so what was it changed to?

My dyno tech checked them when we dyno'd it and they are still on 14 as that's the optimum setting

Are you getting any popping when rolling throttle on/off?

 

[flydnb]

out of interest why aren't the optimum settings there from the get go ?

Optimum for rideability is not the same as optimum for emissions and fuel consumption.

Meaning???

It means that manufacturers may well set the fueling of the bike to meet emissions tests and regulations even though those settings do not give maximum performance. Basically the performance of the bike may be held back by the fact it has to meet certain regulations.

My dealer said because that supposedly damages the cat more. That's why they don't advertise this feature as if everyone starts setting it to 14 and their cats start failing Yamaha will have to replace them under warranty which would cost them a small fortune.

so how big a difference is the 14 setting over the 0 setting ?

That is correct

its about 14 times richer than 0.....

 

[flydnb]

so its burning more fuel or just more efficient ?

 

[Mitch21]

its about 14 times richer than 0.....

14x more fuel or 14% extra or 14 units of fuel extra

its burning more fuel and the pipe makes it more efficient .........but it probably wouldnt pass the emission regs and couldnt be sold running that rich. its all about noise n smog these years......

Has anyone tested, e.g. Dyno'd, setting the C0 to 14 (or other values) with the stock pipe?
