	Conversion charts and information:
	General Notes:	http://www.megasquirt.325ix.com/MS_to_Motronic/General_Notes.html				Read these before doing anything!
	Parts List:	http://www.megasquirt.325ix.com/MS_to_Motronic/parts list.html				Parts list required - will add MS3 related stuff, and any additional BMW parts.
	Grounds	http://www.megasquirt.325ix.com/MS_to_Motronic/Grounds.htm				Maps out all of the grounds for M3.3.1 and Megasquirt.
	C101 to X20:	http://www.megasquirt.325ix.com/MS_to_Motronic/C101_to_X20.html				Convert the E36 X20 to the E30 C101
	E36 / E30 O2:	http://www.megasquirt.325ix.com/MS_to_Motronic/E36_to_E30_O2.html				Connect a wideband O2 (such as the LC1) to the E30/E36 O2 plug.
	Start Circuit	http://www.megasquirt.325ix.com/MS_to_Motronic/Start_Circuit.html				The preferred method for switching the main relay, avoids high current through ignition switch.
	Ignition Drivers:	http://www.megasquirt.325ix.com/MS_to_Motronic/Ignition_Coil_Drivers.h.				Build 6 high current coil outputs for M50 COP, or use the MS3x logic outputs for LSx coils.
	Other Wiring:	http://www.megasquirt.325ix.com/MS_to_Motronic/Other_Wiring.html				Explains MPG conditioner, maps E36/E46 cam sensors, SD card logging switch.
	MS3 Diagnostics:	http://www.megasquirt.325ix.com/MS_to_Motronic/Diagnostics_Port.htm				Bring MS3 serial communication to the Diagnostics port (completely optional).
	Main Relay mod:	http://www.megasquirt.325ix.com/MS_to_Motronic/main_relay_mod.jpg				I'm assuming a similar mod will work with the E36 main relay (use start circuit for best results)
	M30 Auto TPS:	http://www.megasquirt.325ix.com/MS_to_Motronic/M30_auto_TPS.html				For use on M20 conversions; you can also use the E36 TPS with an adapte plate.
