Noticed my car was leaning out on lean cruise today, had previously been fine.
Went to play with the tune and my O2 feedback was off, so turned it on and the AFR hunts quite bad. It cycles between 14.6:1 and 15.6:1 at 60km/h (only had time to look at the 60km/h lean cruise AFR's)
Was just wondering if the AFR's are supposed to hunt like this with O2 feedback on, and is it worth having O2 feedback on at all or just tuning the INJ map at the cruise points to achieve constant desired AFR
Played with the INJ correction for O2 feedback, but didnt seem to make a difference. Came home for a look and in the Celica Forums and it says that the INJ correction value is the maximum value in the INJ Map that it will apply O2 feedback to
If i understood it right
