Any body used Torque model EQ Ratio adjust B3005 in E92 ?

Any body used Torque model EQ Ratio adjust B3005 in E92 ?
I did not understand the benefit from this table but i noticed some E92 will not
follow the commanded AFR so could this table correct this problem ?

Thanks in advance

Have tuned about 10-12 E-92's ---Haven't messed with B3005 at all as I'm not quite sure what it will actually do or over-ride
