	This is the first version of Motronic engine management used on fuel injected E30s, this is what is fitted to pre-facelift cars. The obvious things to spot to tell this from M1.1 & M1.3 are the fact this has an ECU with a number ending 073 and that is has 2 pickup sensor attached to the bellhousing instead of a single one on the front of the block.

	Megasquirt is a complete aftermarket engine management system, designed to replace whatever existing system you have. It offers a more sophisticated platform for tuning your engine, and is a popular choice for those who have already extensively modified the mechanical aspects of their engine. Considering the most powerful engine on the E30 is the [[M20]]B25, then it stands to reason that the vast majority of Megasquirt installations are fitted to that engine.

		+	Another aftermarket engine management system, the Unichip is manufactured by Dastek. Offering the same dynamic control as Megasquirt, the Unichip also saves up to 5 different maps which can be selected automatically, given you the ability to switch between Power and Economy modes as wanted, or any range between the two.

 The ECU plugs are also different over the years, to accommodate the increasingly sophisticated management systems. This makes it impossible to fit an earlier ECU to a later loom.

 '''WARNING:''' One of the most significant differences across the looms is Pin 20. On early vehicles, Pin 20 is a brown earth wire, while for some later vehicles Pin 20 is a live, unfused red/yellow wire for the [[Brakes#ABS|ABS]] system. If you are changing your engine, '''CHECK PIN 20 ON BOTH SIDES OF THE C101 PLUG''' before connecting the battery.
-If you have a brown wire connected, cut it away from the pin, and make sure the free end can't come into contact with anything. If it is red/yellow, then leave it alone
+If you have a brown wire connected, cut it away from the pin, and make sure the free end can't come into contact with anything. If it is red/yellow, then leave it alone. Of course, if the body side of your C101 has a red/yellow wire on pin 20, and your new engine loom has nothing connected to this pin, you need to add a wire, capable of carrying about 15A, from either of the terminals marked '87' on the DME relay socket to pin 20 of the the C101 plug, otherwise your ABS braking system won't work.
 Facelift vehicles also feature a secondary plug. Known as the [[C191]], it sits under the [[Intake#Throttle_Body|throttle body]] and connects up the [[Fuel#Injectors|injectors]], [[Blue_Plug|engine temp sensor]] and [[Instruments#Temp_Gauge|temperature gauge]] to the main engine loom. A number of [[Fuel|fuel]]-related issues, including [[Fuel#Rich_Running|rich running]], can be attributed to corrosion of this plug.

 This wiring harness connects to the main vehicle [[Loom]] through a multi-pin plug known as the [[C101]]. The C101 went through an evolution during the lifetime of the E30, and [[Jetronic]] looms therefore have a completely different C101 to [[Motronic]] systems.
