o2 sensor tuning
i notice on datamaster that my even with
low blm numbers my o2 sensor is reading
between .100 mv - .650 mv which would
say i am on the lean side and my butt meter
says its lean ( the more you push on the gas pedal
it takes a moment for power to accelerate )
am i correct in that low blm's are normally a
rich condition ?

The stock O2 is poor for saying anything more then things are richer or leaner then 14.7.

i have a lambda meter as well
and it shows cruise a/f's of 14.8>15.2
i also have a bad lean spot on throttle
tip in from lower speeds or high vacuum
conditions where it jumps as high as
17.1 for a moment .. i have decent a/f on the lamda
under harder accelerations from 11.6> 12.7
there are two tables to deal with this as
i see it using tunercat software , one being accel vs map
and accell vs tps .. is there a preferred choice ?
this is on a 747 ecm .
