Throttle sensitivity options
DCT owners probably don't care as much but if you have a manual, chances are that the default driving modes are not ideal:
The mode I really want is Sport+ with the Sport throttle response and I don't think I'm alone. But getting there is tricky. Here is what I found so far:
Is there another option? I basically just want two modes with easy switching in between them: Street driving - Sport pedal, TCS/ASC on, regular cooling, rev match Track/spirited drive - Sport pedal, MDM mode, sport cooling, rev match |

PTF locks the map tables for their OTS tunes so you wouldn't be able to edit the throttle mapping but it does let you configure rev match for any mode. Last edited by PackPride85; 10-06-2020 at 08:43 PM.. |

There are a couple of brands of 'pedal tuners' but they aren't cheap and I didn't explore whether they could 'memorise' settings for different driving modes, would be a pain if you had to adjust the pedal setting when going between Sport/Sport+. |

I suppose if you regularly switch between modes, the variation in throttle sensitivity can make it a bit annoying.
But the car is just as responsive and just as powerful in every different mode, provided your right foot provides the right amount of input. Sport+ "feels" more responsive but in reality, you can get just as much response out of the car by simply pressing harder on the throttle. So rather than spending money to recalibrate my throttle, I've just allowed my brain to recalibrate by getting used to it. I see no disadvantage in performance at all. Comfort and traction actually have a very linear throttle response. The other modes have a negative exponential response where almost everything happens in the first half of the pedal travel and the remainder does very little. I prefer the extra finesse available at part throttle but as always, YMMV. If any of you have any experience flying RC aircraft and programming "expo" on your transmitter, you will know exactly what I am talking about. |

Sport+ throttle imo doesn't go well with near/on-limit driving, on track I find there is very very little difference in throttle between a fast near perfect corner exit and going sideways. With my original iStep (July 17 LCI) it was less an issue as even with MDM the traction control would intervene, not so after my iStep was update Dec 18 (to F020-18-11-531). I suspect even the best professional racer wouldn't like Sport+ throttle. With Sport throttle the engine rpm responds (up & down) like an old cabled accelerator. At 0-20% of peddle the power delivery is identical to Comfort and thereafter the increase is gradual (at least to me). It's a lot easier (& safer) pushing the car on the limit. To me it's apparent the manual transmission didn't get too much consideration when they decided on set-up of the OG driving modes (& lack of user customisation), not unlike the arm rest design (height) which is clearly a result of auto/DCT transmission R&D cars.

Sport throttle and MDM would be the sweet spot for a lot of people on the OG M2. I wish we had that choice but apparently, die Deutschen wissen es am besten. |

Speaking of Germans knowing best, it reminds me of a discussion I had with a German friend of mine about which direction sequential shifting gearboxes should work.
Some makers will have 1st gear towards the driver and you push forward to move up gears - these are typically developed from cars with older style automatics that used to have D, 2, 1 on the selector. My previous Volvo was like that. Then there is the PDK, BMW, etc method with 1st gear away from the driver and pull towards you for second etc. My friend said in his thick accent: It's simple, you can do it the German way or you can do it the wrong way. |
