2014–2018 BMW F15 X5 50i - N63TU V8 Twin-Turbo MEVD17 - Performance DME Tuning

BMW N63B44TU with MEVD17.2.H Performance ECU tuning software for BMW F15 X5 50i.

N63tu Stage 1 Performance ECU Flash vs Factory Hardware Gains:

    • Horsepower Increase: 77WHP
    • Torque Increase: 71WTQ

Performance tuning modifies torque limiter maps, boost levels, fuel maps, ignition timing advance maps and more. All to help safely increase HP/TQ, while keeping good drive-ability and factory fail-safes/limp protection in place.

    • We do not offer tuning for emission delete, we do not disable catalytic converter or secondary air pump systems. 
    • We do not offer tuning services to the state of California.

We have 2 methods of having this F15 50i N63tu DME tune installed (Flash Type Selection).

N63TU BENCH ECU FLASH: 

Remove the DDE/ECU and mail it in. We will create a full backup image of your ECU without opening the lid or any physical damage to the ECU at all. We then upload our tune and mail the DDE/ECU back. This is the safest way, as we can have a full backup of the entire ECU content. This is also needed if you have a new bootloader that is OBD2 locked. This prevents OBD2 flashing. We can unlock the DME at no additional charge while installing the bench tune.

N63TU REMOTE DIY ECU FLASH: 

No downtime!!! With this option, once an order is placed, we will ship you an ENET cable, that cable connects to your vehicle's OBD2 port and Ethernet port on the laptop. The remote flash option includes the cost of the cable (which is yours to keep). 
-We will send you a link to download our OBD2 flasher software in an email after your order is placed. Once you have the cable and flasher software, you can then follow instructions to request your tuning file via email. After you receive your tuning file, you can then flash it your self anytime you'd like, if you have technical difficulties and cant figure it out, we can connect remotely via TeamViewer and assist. Be sure to type in your VIN at checkout. In case your DME has been updated by the dealer to the latest firmware, that has a locked bootloader, you will need to send it in for a bench flash/bench unlock. 
-*You will need a Windows 8 or newer laptop  (Apple, Chromebooks are not supported)* 

Will work in the following BMW models:

 - 2014 - 2018 BMW X5 F15, X5 50iX, SUV, N63N, AUTO, USA, (KR63)

Please print out this form and mail it in with your DME. DME will not be flashed until the form is filled out and sent to us.
