For sale is a fully functional JB4 taken off a 2015 428xi GC. I no longer have the car as the lease has finished. Works with N20/N26 engine. JB4 has EWG board and comes with a weatherproof rubber enclosure and USB data cable. I was never able to go to stage 2 on the car as I never got the right mods since it was a lease. But even in map 1 this made a day and night difference in the car. It came alive on the highways and the backroads. The car sounded much more aggressive and pulled much harder. It even had exhaust burbles! I loved every second of it and I am sure you will too. Prices can be negotiated. PM me for questions. |
