This is the DINANTRONICS X - for BMW years 2013-2019 550I/650I/X5 50I/X6 50I (includes the Xdrives of these models) The stock Part # is D440-0139. You can verify this for your car right through the Dinan website. Comes complete with original packaging. This came off of my car which is a 2013 BMW 650i xdrive. As you all know, Dinan has long been the go to for all BMW's performance enhancements, as they do not void any warrantys and do not cause any check engine lights what so ever, it also does not interfere with the NYS inspection. As My car was inspected with the tune from BMW in Rochester with no problems what so ever. This tune has 7 settings, 0 through 7. 0 leaves the car completely stock, with a simple button click you can change the tune from 0 through 7. The highest setting of 7 requires you to run 93 octane, which I always ran in my car anyways. The tune is adaptive to any other mods you may do to the car (exhaust/xpipe/downpipes etc) as it learns what mods the car has. I am selling the car and selling the tune separately.
Absolutely nothing wrong with it. I had it installed and removed from "The Little Speed Shop" right here in Rochester NY. They are the number one guys when you're looking to do any upgrades to your BMW. However it is simple enough to install yourself.
Original boxing/instructions etc all included.
