Heya EFICU,

Please take a look at a these data logs. I know they are short, but my concern is the cruising, high way speed A/F ratio of 29.4
Is this normal?

Thanks
Jeffn

Yes, it is normal. When the fuel injectors are cut during overrun then the exhaust will contain a high o2 content and the wideband will read lean.
