    The N63 motors have found no love because of the limited enthusiast market. A few of us got into the platform and are still hoping to get a decent flash tune possibility. Recentlty OBD bench flashing has become a reality on this ECU and we're trying to get definitions going for the ECU Dump. Help is very much needed and appreciated. Trying to log and document efforts here. attaching an EEPROM dump here to start off- thanks to Sergey Birioukov for the ECU file.

    Still trying to find a Damos file to start extracting tables. Its out there and if anyone have access to one, help is greatly appreciated

    I didn't realize this ecu wasn't cracked already! I was really rooting for the N63 when I first heard about it. So basically, its all the xDrive '50' cars from around the same window as the N54. You'd think the N63 and S63 would be massive power plants considering the displacement and the factory forced induction, does the S63 use the same DME?

    S63 came with this ecu as well as the Bosch one. S63 with Siemens was a very limited run in the x m models if im not wrong. the xdrive 50s and f10 550, 650 and other 50 models from roughly 2010- 2013

    While waiting for a damos, we listed out the OBD PID's from tool32 prg files. its added in the drive if anyone is interested in logging. shoutout to Matt Provenzale for his help and Wedge for the method.

    Hey thx for mentioning me, looks like we are all still struggling to find the PID, i saw matt wrote some code to auto test the codes. im going to link him to this thread.

    So there is a Siemens and Bosch ECU for the S63. Which is flashable and which N63 cars do we need to buy to get this ECU?

    latest is Matt wrote a program to test every PID that returned a value but none referenced target boost. the general consensus is BMW might have written some custom logic for boost control not using Seimens logic as Funktionsrahmen referenced id's do not work as well. I believe he said target boost is not referenced in Rheingold or tool32 for this ecu to sniff it either. im gonna sell my car and get a TU lol
