Swapping an S54 into your e30? Got the wiring down but don't know what to do for your DME (S54 ECU)? Don't want to pay to delete EWS, yet have Speed control working, and have control yourself?
After much research and wanting to learn myself what was going on, I have made TunerPro XDFs available to all for this process. This in no way will let you tune your car for more power, but it will get it running with the proper DTCs (Diagnostic Trouble Codes) to disable and modifications to make this work smoothly. Thanks to TAP, POLAR, SLIM, TERRA and MANY MANY more for their work over here
The goal was to share much of this over there, but it's slowly been abandoned, and the "complete" XDFs to have major mapping of the ECU available to the masses has gone missing for fear of BMW's retaliation and the possibility of killing your engine or yourself. EDIT: NO LONGER TRUE, I hosted them on Github! I like to have control, and not blame others for trying to install an S54 with working Cruise Control into my car, so here. Share. Use. Enjoy your car and learn how to fix it yourself if you can. I am here to help if I can for as long as I have my E30, but alas I am not always available.
Software: MSS Flasher, BMWFlash, BMW Logger, FT Prog (to edit your ODB2 FTDI Cable)
Excel files: to correct values for Speedo Calibration, Gear Recognition Observations, and Cruise Control
YOUTUBE Tutorial
MSS54 ECU Tutorial Part 1: Tools and Reading/Writing to your ECU
MSS54 ECU Tutorial Part 2: Swap Coding
Currently works for:
MSS54 - v2601, v2801
MSS54HP - v1801, v2001, v2501, v2701
Click here to Download the Software and Definition Files along with some help. READ THE README and DIY PDF
Also, Here is how to get cruise control working
NOTE: Usage of this is free, knowledge of this is free as well, meaning, please use your brain to understand why you are changing these items. These are the common swap items and DTCs to disable. Using an SMG? Modify the value to your needs. Using the Rear O2s still? Don't disable that DTC! Using a Z3M or E36 Guage cluster, use the correct Speedo Source? Using MK60 ABS? Yes! It's your build. Customize your swap coding. HOWEVER, if you need help, PM me, I will help for a small fee as long as you can pull your own file. The days of shipping the ECU are dead.
