Remarks: the map KFMIRL is used in the funktionsrahmen module MDFUE 8.50 with inputs of engine speed
and the target torque for the charge pathway, recalculated at lambda = 1 and zwopt (misopl1_w) to calculate
the target cylinder charge. Note that the higher values are greater than 191.0% in KFMIOP and greater than
the maximum of 185.3% in LDRXN for the BFV engine which places an upper limit on the KFMIRL output via
the variable rlmax. There is no difference between the BAM & BFV maps for calculating target charge.
KFMIRL should be used to tune part-throttle torque response. Please note that it is stated in module
MDFUE 8.50 Application Notes that the map KFMIRL is the inverse of the map KFMIOP in module
MDBAS. Therefore, any changes made to KFMIRL should be reflected in KFMIOP and vice versa. If
the difference is too large, problematic operation/torque intervention will be experienced. Inverse in
this sense is assumed to mean ‘complementary’, not the exact arithmetic inverse.
