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 only offer one flashing type for this car (Bench Flash).
BENCH FLASH: Remove the ECU/DME and mail it in. We will create a full backup image of your ECU/DME without opening the lid or any physical damage to it. We then upload the tune. This is the safest way, as we can have a full backup of the entire ECU/DME content.
If you're a local in the Seattle area in Washington, you're welcome to stop by and we can do this in person without having to remove the DME from the vehicle.
Removal of the DMEs is very simple, on almost all models the DMEs is located in the black electronics box near the firewall on the passenger side under the hood. The 750iL model uses 2 DMEs.
