This DME (engine computer) software upgrade is for:
BMW E39 M5 - Engine S62B50
Other BMW models with S62B50 conversions/swaps.
We have 2 methods of having this tune installed (Flash Type Selection).
Method 1 - BENCH (Recommended): Remove the DME/ECU and mail it in. We then upload our tune of your choice and mail the DME/ECU back.
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.
Method 2 - REMOTE FLASH: We have an available option of flashing your ECU/DME remotely through the OBD2 port of you vehicle without removal of the ECU/DME. We mail out a OBD2 flash cable to you that you will keep. It will allow us to do any future updates or follow up flashes at later times as well. Windows XP or newer laptop is required, as well as an available USB port. In some rare cases, remote flashing doesn't work, we would have to go to bench flashing method.
