Wideband Numbers/Settings

[fradiecat]

Just installed a KOSO wideband on my 06 CF-7.
What are the optimum numbers to shoot for?
Are larger numbers fatter?
I'm aware I need to verify settings with plugs/wash
so no need to scold me on that.
Tried searching but most posts are about where to pull power from. Mine is up and working, now need to know
#'s so I can dial in headache box.
Thanks!!

No - higher is LEANER.

AIR to FUEL ratio. IE - parts of air to parts of fuel. you should be shooting for mid 12's at WOT, and upper 13s to low 14s at cruise and idle.

Hope this helps.

The Koso is sorta slow on the up take, so you gotta keep it the throttle position steady to get the right numbers. Hope that helps!

Yes it does, Thank you.
Sitting at idle it says 14.3 now

These are the numbers i got from SLP for the koso gauge.

Idle: 14-1 to 16-1

Low load part throttle (up to 50% throttle opening) 14-1 to 15-1

Low load part throttle (50 to 65% throttle opening) 13.5-1 to 14-1

High load above 65% throttle opening: 12.2-1 to 13.2-1

I wouldn't worry much about that idle number. I added fuel until mine bogged and died and it said 14.2 the whole time. You won't get real numbers until you start riding.
