We have 2 methods of having your E38 V12 M73tu Tune installed (Flash Type Selection).

 - E38 750iL M73B54tu 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.

 - E38 750iL M73B54tu Remote Flash Tune (Recommended): 

With this option, once an order is placed, we will ship you a cable, that cable connects to a laptop and we are able to remote into your computer to flash the car. The remote flash option includes the cost of the cable (which is yours to keep). If we are out of cables for remote flashing, we can offer a cable for rent with a deposit. (We will message you if this happens). In some cases, not all cars can be flashed this way. In that case, you will have to ship your ECU to us for a bench flash. You will need a Windows 8 or newer laptop and WIFI to flash remotely (Apple, Chromebooks are not supported)
