Hello, all. Firstly, I'm new here, so I may not be in the right place, but hopefully I'm close.
I've got an early 2000s 323i at my garage where I work, and my boss has told me that I could have the engine and tranny out of it, since the person who was buying it blew a head gasket. Yes, I know that head gaskets can be a pricey fix on a BMW, but I have a car that I would love to drop the engine and tranny into. My question is this: what all electronic parts do I need to pull as well? I know that I can backtrack from the engine and such, but that's just that much more time consuming. And the other question I have is this: is there such a thing as a simplified ECM that doesn't control the air, radiator, and every other function? I just want one that will purely run the engine. :dunno:

I'm a mechanic, but I'm more used to older cars. Much simpler times, then. Not all this computer BS.

2000 is an e46 chassis, so you should probably check with them,

that being said, what car are you planning on dropping the engine/trans into?? auto or manual?? :dunno:

if you are not well versed with computer engine controls, perhaps the companies that specialize in stand alone systems would be beneficial for your plans?? :dunno:

Computer wise, if you dont need all the extra controls, there are cheap alternatives that can and will just run your engine.
Check out megasquirt, or even some haltech products, very good bang for buck, around the US$1000 for a kit, and you can wire it in however you want.
Then maybe another $100 for plugs and other connectors etc.

My guess is it will be a manual transplant as the auto gearbox requires that horrific gearbox contorller unit.

Also dont forget, the e46 was not very advanced in regards to electronics, did not have stratified injection, and traction control, stability control usually is controlled by a seperate ecu.
