Just installed mine one today. I ordered it of the ebay, received in about a week. Installation was pretty easy, only needed to buy a 3/4 drill bit had rest of the tools. Here are the pictures.
I haven't had a chance to test it yet, but could feel the throttle getting more responsive along with steering becoming a bit firmer. The engine RPM also increases, its not same as SD mode for sure will keep you guys posted once I test it.
Bought the LED button from Roskinc, looking for shop to help with installation. Suggestions please? Dropped by one accessories shop in Damansara Perdana asking for crazy money..
Mine is pre-LCI model and I have installed the cable with ordinary micro switch. I am still trying to figure out where to locate and install the BMW original switch.
