This DME (engine computer) software upgrade is for:
BMW E39 M5 - Engine S62B50
Other BMW models with S62B50 conversions/swaps.
The DME will have to be sent to us in order for the DME to be updated with performance software. If you're a local in the Seattle area in Washington, you're welcome to stop by and I can do this in person without having to remove the DME from the vehicle.
We also have an option available for remote reflash of the DME for MSS52/MSS54/MSS54HP
Removal of the DME is very simple, on almost all models the DME is located in the black electronics box near the firewall on the passenger side under the hood. If you have any concerns or questions, feel free to send me a message.
