Alright everytime I look I get a different answer or read something different.

When viewing block 031 on a NDBW AEB engine is .85 richer than .90 or leaner???

Please someone that really knows what their talking about please chime in and lend a hand. thanks.[wrench]

Higher # is richer on a ndbw since it has a narrow band 02 sensor.

On a wide band sensor(2001+) or for those that run a after market wide band setup higher is leaner since 1.00 = 14.7:1 and as the #'s get lower you just multiply it with 14.7 to get your AFR.
