Ask me how I know ... I wired up my edis ignition without any f**ks given to make sure it worked as it was intended to. Now I am going back and rewiring it all to actually make it organized and clean looking. I hit myself for not doing it right in the first place. Just saying.

Looks like a great project nonetheless. Keep it up!

Honestly not that hard to wire up a standalone. only so many sensor eh? and Chances are you are modifying stock stuff anyways when doinga  turbo build.

I put piggyback on my turbo tiburon waaaaaaay back in the day and it was a pain in the ass. Putting megasquirt into the beem now will be so much smoother and nicer I reckon. The SAFC has been used in a multitude of vehicles tho.

I would imagine there is not a way to convert the AFM signal to MAP or MAF with that and you would be limited to using an M30 AFM

If you go that route, let me know, I want to see it in person and touch it and mess it up and all that jazz.

The harness is really pretty easy to remove and replace. You would need to run high impedence injectors from 325i, The only thing I can think of being different at the moment is the trigger wheel. I am not sure if MS supports the triggerwheel setup that the 'e' motors have. 

BUT 

you could install an 'i' trigger wheel on the crank and just make sure it gets wired into the stock harness correctly

But since I had no choice, I went the used route and bought a board already assembled and will be having the joy if wiring everything up to my engine sensors soon.

Don't be scared at the wiring and stuff. I would be more scared to build the board! I say you should buy a ms3 and gut an old e28 ecu case if you want it plug and play, and wire the necessary connections to it. I say buy something Pre-assembled.

The only thing youd be missing by getting a DIYPNP vs one built into a e30 ecu is that whodwho incorporates a circuit in the ecu that allows you to use the stock e30 TPS, but this is not desirable, a variable TPS like what an M50 has is far superior for tuning and running the car. 

You could get the DIYPNP setup with the bosch 55pin harness (stock e30 325i ) so you would just need a 55 pin harness on your car to connect into it, then get aluminum plate, drill some holes in it, mount the ecu to the plate, and the plate to the stock ecu location.

 but to be realistic,  a wideband, GM intake temp sensor, bung, misc air intake mods, and M50 TPS + adapter would probably get the total price  around a grand.

http://www.r3vlimited.com/board/showthread.php?t=202653

I still have the NA tune on the ECU but it would take a whole 5 minutes to make it work for my new bigger injectors and a turbo (fine tuning required of course). I will probably do that tonight. 

the cost shouldnt freak you out, but one way to look at it is, if your car rusts out, canadians stab it with popsicle sticks, or if earl polishes every bolt on it, you can take the ecu and use it in any other car (monte carlos, bitchin camaros, integras, vw cabriolets etc) as long as you make the appropriate changes in the tune (change number of cylinders  and injector size for example) and adapt the wiring harness to work.

Rowley,  are you telling me that you can run wasted spark on 1 coil driver?!?!?

Im not doubting or anything, I haven't read up much on alternate ignition setups so I may learn something from you here. 

 Oh hey I forgot about ms2 only having one. I have MS3 so I went with the easiest setup...
