E60 M5 vs E92 M3 Throttle Response and MDM
Long time lurker, first time poster! after 3.5 years of dreaming and procrastinating I finally purchased a 2006 E60 M5 SMG. The car is everything I hoped and dreamed it would be, and whilst I am trying to block out a lot of the noise from all the experts on the interwebs about reliability issues, I do have a healthy allocation of contingency funds for the inevitable repairs (...this is not my first older BMW).
All that aside, I have a question regarding throttle response and MDM:
I took the car for its first proper spirited drive in the hills yesterday with a friend in his Cayman GTS and a friend with an E92 M3 DCT. The M3 has primary cat delete with aftermarket mid pipes (stock rear box), and a tune (I cannot recall which one).
Driving the E92 M3 back to back with my M5 made me realise I need an aftermarket exhaust, but also that the M5 feels a lot tamer with regards to the amount of slip that MDM allows and much less aggressive with regards to throttle response (even in P500 sport). The MDM of the E92 in a straight line feels more like ESC off in the E60.
I feel that in the M3 in MDM in combination with the more sensitive throttle, the car feels more visceral than the M5 with power feeling more linear, especially at the lower end. Has any one else experienced this?
I realise that MDM tuning is what it is, however will I be able to match the throttle response of the S65 with a tune, such as FAMS?
