Today I played with the CO adjustemt tool, while having the O2 sensor connected.
Guys, make sure you are seated well:
CO O2 Voltage
-26 0.08 "lean"
So my bike with my muffler/header and open airbox door (FI diagnostic tool)
develops lean idle only with a CO value below -25
That's right. Everything above -25 is on the rich side.
So I dialed in -24 and through all my subequent freeway racing O2 sensor experiments (see other thread)
chopping the throttle closed got my some high 0.8, 0.9 reading, CO -24 is A/F ratio wise rich idle !
finally, at CO value set to -26 there is lean idle mixture:
Guys, please let's try and keep that thread focused on CO setting and idle mixture only.
A/F ratio and mapping is here:
