I recently read on the BMW BLOG about an owner that utilized the OBD II connection and available software to change the settings to the European "Enable REx Hold option". With the REx engaged at 75% SOC he was able to drive from the (San Francisco) Bay Area over Donner Summit to Lake Tahoe. This is the "tune" that I have been waiting for. It does not suddenly make the i3 a great car for regular long trips, though it does unlock the opportunity to drive on those rare occasions when a couple hundred miles in a weekend is required, without plugging in.
95% of my driving will fall into the electric range and another 3-4% within the regular extended range. While I may only need this capability once a year it has been the reason I have not moved ahead with the i3. Now I am planning to do a three day test drive and look into the logistics of getting a 220 volt charger in my garage. While I am reasonably competent technologically, I still would not mind assistance with the coding change, could be a new cottage industry. Has anyone here made this tweak?
