This tune is for:

BMW E38 (750i/iL V12), engine  M73B54, we can also tune euro spec'd 750i/iL no problem if you're outside of USA. 

Other BMW models with a  M73B54 conversions/swaps.

 

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

  • BENCH: Remove the 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 ECU back. This is the safest way, as we can have a full backup of the entire ECU content.
  • REMOTE FLASH: 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)*
