Do It Yourself: Sport Mode.....(S54 M-Coupe and Roadster)
Good luck. *th-up*
SPORT MODE IS AMAZING.... read on....
For those of you who own an S54 powered Coupé or Roadster, the sport mode (as you well know) was not a factory installed option. Rumors abound; this was done to meet strict California EPA emission standards, limit the potential so as not to beat BMW's own M3, and safety precautions (as ZM3's are known to bite the uninitiated very hard!!).
As such, the dealer charges ~$500 for this install; which, by the way, does NOT void the warranty. Although, after having successfully installing the mod. myself, I can't imagine why in the world the dealer charges a ludicrous amount of money for this?! Aside from the fact that it takes about 1-2hrs to complete (includes properly soldering the wires), it is a very simple process.
For anyone in the GTA that is interested, I am offering to install this mod or help install it.
A short shopping list of parts is necessary of course:
18 Gauge wire
Single Momentary switch (ASC button will do fine!)
Pin for the ECU.. BMW part #61-13-0-005-197 (usually in-stock!)
Soldering gun, wire and flux
10mm wrench (to disconnect battery)
P.S. The sport mode in these car's is phenomenal *mw* ...
What exactly does the sport mode offer?
The Sport Mode offers you the grace of God!!!
Really though.... the sport mode activates different mapping for the throttle.
Since the S54 engine (2001-2002 M-Coupe/Roadster + 2001-2004 M3) has servo controlled throttles (meaning it's not mechanically operated via cable) the computer can essentially adjust the sensitivity of the throttle.
What it bears down to is the amount of pedal travel necessary to open the throttles. Sport mode is direct response (think of an aspect ratio of 1:1) where normal mode is delayed (1.2:1 - or something similar).
