I personally use a very very similar map on my N54 and it works wonders if someone wants to tweak their burble to their liking. I can't verify it for anyone as my friends car never starts after flashing the RSA Delete and tune file afterwards.

ip_mff_cor_opm_1_1 (1_2, 2_1 and 2_2) are the fuel scalar maps for those running extensive mods and may or may not be useful.

For anyone that wants less nannies in the software, I would disable DROF, lc_tq_iga_inh, lc_tq_lim_inh (general), lc_tq_lim_inh_fast, lc_tq_lim_inh_slow. Setting those toggles to 1 should disable it.

I would also recommend simulating the 1M throttle maps by changing the torque request maps and copying the 1M values and breakpoints and reducing the throttle correction (ip_fac_pv_bas_cor_transmission) to 0 on MT (reduce numbers by half for a good starting point on automatic cars as they get real twitchy at 0)

I can't provide any guarantees as the only MSV70 I have access to doesn't even start up after BimmerLabs batch flashing. I have tested out all of these maps on my MSD80 though.

How to get such burbles when changing gear in an automatic transmission? Can you suggest which values ​​will be a good start? msv70
