Default help choosing honda ecu for project turbo bmw

my friend has a 72 bmw 2002 and he's hoping to turbo it's 2.0L SOHC engine. He wants to use a honda ecu as a sort of cheap stand alone. He'll adapt a honda distributor to fit the bmw engine. What he needs to know is what ecu to get (if it matters).
Thanks for any help

Is that even possible without switching all the sensors/harnesses etc.? Just curious.

If you use an OBD0 distributor, use and OBD0 Ecu, OBD1 Distro, OBd1 ecu

I guess a nonvtec one..

no experience in this but from my thoughts you'd want something that matches as closely
to the engine you're hooking it up to?

So maybe an LS or CRV ecu?

I would say a PM6... it's the most simplistic with the most features.

You probably dont want to go OBD1 due in part to all of the sensor checks that would have to be faked, or removed. OBD0 is very easy to kill sensors in. Plus, you have any features you'll need.

i have always thought about doing this to my 92 Jetta i know you would need:
dizzy, ecu, coolant temp, IAT, O2, TPS, and MAP sensor
but what about the main relay and fueling, how would that work?

You'll have to machine the stock cam to fit the dizzy.
main relay well..you can just split it in two relays that are commonly used....the main relay is just 2 relays in one.
A friend of mine made a schematic to use 2 seperate relays instead of the the honda main relay.
The rest doesn't seem to be a problem. it will just have to take some work and a little creativity.

Yeah, I agree. By the time you're done paying for all the parts, and modifying everything, it'd most likely be easier and cheaper to just buy a pre-made Megsquirt setup.
