Should follow the values in the Open Loop Fueling Table under load
Rough guide to expected AFR (Naturally aspirated on petrol)
Cruise and idle around 14
Overrun –throttle closed will often read 20
Under load low to mid RPM , AFR around 12-13
Under load high RPM , AFR Mid 12 than tapering to maybe high 11 over 7000 on OFT tunes.
Have a read of the Ecu Logging link below (green one)
