We have 2 methods of having the E39 M5 ECU Tune installed (Flash Type Selection).

 - BMW E39 M5 S62 Bench Flash Tune: 

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.

 - BMW E39 M5 S62 Remote Flash Tune - Recommended: 

No downtime!!! With this option, once an order is placed, we will ship you a cable. 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. 

*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.
