This DME (engine computer) software upgrade is for:

 Range Rover with M62TU BMW 4.4L Engine

We have 2 methods of having this tune installed (Flash Type Selection).

Method 1 - BENCH:  Remove the DME/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 DME/ECU back. This is the safest way, as we can have a full backup of the entire ECU content.

Method 2 - REMOTE FLASH (Recommended): No downtime!!! With this option, once an order is placed, we will ship you a cable, that cable connects to a laptop. You will then be able to connect the cable to your obd2 port and laptop, and we can read/write your DME/ECU via teamviewer. 

*You will need a Windows 8 or newer laptop and WIFI to flash remotely (Apple, Chromebooks are not supported)*
