both are using wideband to adjust primary ve table

if there's diff, when should you use 1 vs the other

any thoughts on how one would calculate the average mpg for an entire log scan ?

i would expect tuning to be unique to each ecm/engine, unless 2 tuners had identical stock engines

play with deceleration fuel cut off(DFCO), upshift/downshift tables, & torque converter lockup...
