The Burger Motorsports JB4 reads and adjusts through the engine's own sensor network, so there is no flash, no VIN lock, and no trace once you unplug it. Figure roughly 20 minutes to install with hand tools.\u003c\/p\u003e\n\u003cp\u003eThe N55 changed connectors partway through production, so harness type matters more than model year alone. Type A covers most 2011 and some 2012 cars; Type B covers some 2011, most 2012 and all 2013+ cars, and right-hand-drive versions of both are available.
