[R3Z3N]

What?

S54 Swap Wiring Harness for your E30 with Round C101 Plug. Early Models will need to convert to this plug or create their main swap plug using 3rd party connectors such as TE's robust line. Click here and here for info. Tips and tools for wiring your C101!

Why?

Forum members and providers of services come and go in this life. I want to immortalize it here and on Github, and anywhere else people would like to host it. I sold my S54 E30 swap last year, but I want to help others.

Who?

Me and anyone else that would like to contribute. Shout out to DesertBMW, FredK, R3VM3UP, Andrew325is, Terraphantm, Paffy, Tap, Nando

Cost?

Your time. Priceless. Your dignity.

How to Flash your ECU for YOUR build:

For Now Please reference my DME Coding Tutorial and Github for coding/tuning and swap XDFs to further customize for your needs. The Wiki is also your friend. I recommend getting familiar with flashing your MSS54/HP (ECU) as builds can vary greatly. IE did you wire in more such as the gear position sensor? If so you do not need to code it out. Are you using the PWM fan but no K-Line converter such as GPetersons? Then you need to follow disable the fallback 60% fan speed as seen here. IF YOU NEED HELP, OR DO NOT WANT TO CODE YOUR ECU, I WILL DO IT RELATIVELY CHEAPLY. PM Me for info.
