=== Optional accelerator pedal changes === B58 pedal feel is set using a twofold lookup. First, the range of torque available (vs RPM) is provided by ''Torque request ceiling'' and the driver's pedal position is scaled into this range. Then a relative torque request table is selected according to the driving mode. The tunerpro XDF's expose relative torque request tables for the sport modes (with and without manual shift selected). If you have the a2l for your platform, you might also want to add the addresses of drive mode with manual switch (KF_MDR_ABV_D_HS) or drive mode with auto (KF_MDR_ABV_D). ==== Relative torque request sport MT 1 ==== '''Ref''': [[DME_table_reference#Relative_torque_request_sport_MT_1|Relative torque request sport MT 1]] '''Brief description''': KF_MDR_ABV_SPO_HS '''Dimension''': 2D, table '''Categories''': Throttle '''Unit info''': -, - --> - '''Breakpoints''': Relative torque request sport MT 1 X (autogen) vs Relative torque request sport MT 1 Y (autogen) '''Base''': 0.000 8.200 16.000 43.300 150.000 190.000 220.000 230.000 250.000 270.000 0.0 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 6.0 3.230 4.383 4.715 5.785 6.551 7.059 8.125 8.125 8.125 8.125 14.0 9.063 12.191 13.109 16.078 18.211 18.820 25.156 25.156 25.156 25.156 22.2 18.453 23.090 24.824 28.617 32.129 33.043 42.598 42.598 42.598 42.598 33.3 35.816 40.871 42.637 47.199 52.109 52.820 65.070 65.070 65.070 65.070 44.4 51.566 54.809 55.922 60.039 67.590 69.215 80.328 80.328 80.328 80.328 55.6 63.309 65.605 66.598 70.070 77.539 79.570 88.211 88.211 88.211 88.211 66.7 73.152 74.512 75.414 78.559 85.137 86.355 93.414 93.414 93.414 93.414 77.8 81.480 81.902 82.730 86.176 91.258 92.172 97.305 97.305 97.305 97.305 88.9 87.766 88.652 89.102 92.348 96.129 96.941 99.793 99.793 99.793 99.793 94.5 93.883 94.328 94.551 96.176 98.066 98.473 99.898 99.898 99.898 99.898 100.0 100.000 100.000 100.000 100.000 100.000 100.000 100.000 100.000 100.000 100.000 '''Difference''': 0.000 0.000 0.000 8.200 16.000 46.000 72.000 100.000 250.000 350.000 0.0 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 6.0 0.000 -1.152 -1.484 -1.402 -1.836 -1.273 -1.574 -1.066 0.000 0.000 14.0 0.000 -3.129 -4.047 -3.887 -5.102 -2.742 -6.945 -6.336 0.000 0.000 22.2 0.000 -4.637 -6.371 -5.527 -7.305 -4.426 -10.469 -9.555 0.000 0.000 33.3 0.000 -5.055 -6.820 -6.328 -9.473 -5.621 -12.961 -12.250 0.000 0.000 44.4 0.000 -3.242 -4.355 -5.230 -11.668 -9.176 -12.738 -11.113 0.000 0.000 55.6 0.000 -2.297 -3.289 -4.465 -10.941 -9.500 -10.672 -8.641 0.000 0.000 66.7 0.000 -1.359 -2.262 -4.047 -9.723 -7.797 -8.277 -7.059 0.000 0.000 77.8 0.000 -0.422 -1.250 -4.273 -8.527 -5.996 -6.047 -5.133 0.000 0.000 88.9 0.000 -0.887 -1.336 -3.695 -7.027 -4.594 -3.664 -2.852 0.000 0.000 100.0 6.117 5.672 5.449 3.824 1.934 1.527 0.102 0.102 0.102 0.102 100.0 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 '''Modified''': 0.000 0.000 0.000 8.200 16.000 46.000 72.000 100.000 250.000 350.000 0.0 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 6.0 3.230 3.230 3.230 4.383 4.715 5.785 6.551 7.059 8.125 8.125 14.0 9.063 9.063 9.063 12.191 13.109 16.078 18.211 18.820 25.156 25.156 22.2 18.453 18.453 18.453 23.090 24.824 28.617 32.129 33.043 42.598 42.598 33.3 35.816 35.816 35.816 40.871 42.637 47.199 52.109 52.820 65.070 65.070 44.4 51.566 51.566 51.566 54.809 55.922 60.039 67.590 69.215 80.328 80.328 55.6 63.309 63.309 63.309 65.605 66.598 70.070 77.539 79.570 88.211 88.211 66.7 73.152 73.152 73.152 74.512 75.414 78.559 85.137 86.355 93.414 93.414 77.8 81.480 81.480 81.480 81.902 82.730 86.176 91.258 92.172 97.305 97.305 88.9 87.766 87.766 87.766 88.652 89.102 92.348 96.129 96.941 99.793 99.793 100.0 100.000 100.000 100.000 100.000 100.000 100.000 100.000 100.000 100.000 100.000 100.0 100.000 100.000 100.000 100.000 100.000 100.000 100.000 100.000 100.000 100.000 '''Notes''': The throttle changes are optional. These tables affect pedal feel in the various driving modes. The tunerpro XDFs expose sport driving modes. There are also tables for drive (i.e. comfort mode) and ecopro, though these are not described in the XDF. The basic idea is to stop the car from getting too jumpy in traffic but give a sense of power on the open road. The MPPSK rescales the x breakpoints and so vectors the torque differently. The x axis is the unmodified torque request (i.e. max torque request x accelerator pedal position) and the y axis is itself the pedal position. TODO: according to https://f30.bimmerpost.com/forums/showthread.php?t=1734153, the x axis is vehicle speed in km/h, however, this seems odd because 350km = 217miles, which is an unrealistic speed to be thinking about pedal feel. Confirm if x axis is torque in Nm or speed in km/h? ==== Relative torque request sport MT 2 ==== '''Ref''': [[DME_table_reference#Relative_torque_request_sport_MT_2|Relative torque request sport MT 2]] '''Brief description''': KF_MDR_ABV_SPO2_HS '''Dimension''': 2D, table '''Categories''': Throttle '''Unit info''': -, -
