Ok i just installed my wide band and at idle it's around 15.2, just cruising around 14.7, whooping on it it goes to around 10.9 and under deceleration it goes to 20.0. Can someone explain to the idiot (that would be me) what these ####'s mean as far as to rich or lean should i get another re flash or not?

 

15.2 at idle is normal, 14.7 at cruise is normal and the car is most likely in closed loop, 10.9 at WOT is rich should be around 11.5, 20.0 when you lift off the throttle is normal as well. The only thing that needs adjusting is your WOT air/fuel ratio for optimal power.

 

whats the problem with the numbers. seems about right. a little rich under throttle but seems like a safe tune.

 

The problem is the OP did not understand what the air/fuel ratios were supposed to be under the above listed conditions. Seems he is just trying to confirm that everything is in order and asside from the rich WOT air/fuel ratio everythings fine.

 

Thanks for the input

 

My idle is always 14.7

 

higher the number means leaner lower the number means rich correct me if im worng

 

This is correct. With a race fuel optimal is low to mid 12s and with pump you want low to mid 11s for extra knock protection, since the fuel can be inconsistent. Anything in the 10s is a bit on the rich side. As far as idle and part throttle go, 14.7 is suppose to be optimal, but I have seen people run a tad leaner. If you start getting misfires then you are too lean (part throttle).

 

glad you enjoying that wideband
