We have 2 methods of having your E39 M62TU Tune installed (Flash Type Selection).

 - E39 540i M62B44TU Bench Flash Tune - 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.

 - E39 540i M62B44TU Remote Flash Tune (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 read/write your own DME/ECU on your own. Best of all it's most convenient for you to flash it anytime.

We will send you our new flasher software to download with instruction. With this flasher tool you can Read and Write our tuning files by yourself, and also be able to read/clear fault codes and adaptations. It will also be able to show you live data for easy diagnostics.

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

INPA/Bimmergeeks K+DCAN cable will also work and are supported for remote flashing. You will need to purchase a cable from us for remote flashes if you don't have one.
