obd2 m52 swap problems.

[87e30]

Alright, I have an OBD2 motor in my 87 325es (e30).

I have it running... but it misfires horribly and isn't driveable. It took me a while to get all figured out since I'm not too experienced in this field, and I did initially hook up a ground to power (n00b I know) which made a popping noise and a small burn marking on the case of the ECU.

Here's the deal, I threw a laundry list of codes.
12, EWS Signal
08, Air Mass Sensor
14, Check Engine Lamp
d9, CAN Bus timeout
3d, After-cat 02 sensor heater, cyl 4-6
4f, After-cat 02 sensor heater, cyl 1-3
44, EVAP System, purge control valve ckt.
32, EVAP System running losses valve
34, Rear Exhaust Valve Flap
06, Fuel Injector Cyl #1

So I identified MAF, O2s, and Fuel Injector 1 as my major problems and I'd go from there.
(If someone knows much about CAN bus timeout that would be nice, I'm wondering if it has to do with traction control delete)

I got a new MAF, flip-flopped the 02 conections, and took apart the fuel rail and injectors, replacing injector number 1.

Reset the codes, drove the car and it drove better. For a couple minutes until it started to warm it was driving really smooth. But when I was feeling good I decided to open it up and at 5000 or so rpm it cut out completely. Also began stumbling and misfiring often. Then finally began to die if it idled.

So I pulled the codes, here's what I got:
14, Check Engine Lamp
d9, CAN Bus timeout
3d, After-cat 02 sensor heater, cyl 4-6
34, Rear Exhaust Valve Flap
06, Fuel Injector Cyl #1

Now I'm confused. I don't get why the EVAP and EWS codes would go away as I changed nothing, and I don't get what is wrong with Injector number once since I replaced it. If it was a misfiring code I could test spark but it's not...

Apparently one o2 is truly bad while the other is now connected properly, not too worried about that situation. I think it's just the Injector 1 code that is keeping the car from running right, correct?

(I still have lingering fears that I fried the ECU but in order to try a new one I'd have to get it aligned for the EWS which costs money, and if it wasn't the problem then I just literally threw away 150 bucks)

Input from the m52 and BMW masters would be so appreciated. 5 months with out my car and I'm getting pretty damn frustrated. I hope this was all clear.

PS: I don't want to hear should haev gone obd1, while this MAY have been true I didn't, I'm here, and I'm close so I'm staying obd2.

Thanks.

That thread outlines everything, I believe.

all that spound like an dme issue, the exhaust flap should not be thrown and neither should the heated o2 sensor code, the can bus is something that i know your car doesnt have. that pop and hole you have in the dme probably means bye bye to that comeputer. if fuel injector 1 is throwing that code do you have any idea why? did you check out the injector? and the wired and stuff? but that will cause it to run crappy yes. but that all sounds like if you have a chip in the comp that you may have fried it or the computer so it thinks its back in an e36
