OK so where I am now.... Plugged the car into Delphi Autocom last night and checked the fault codes. Also compared what was and wasn't working between the e36 and e46 using the same re programmed ecu in both and then the known working unprogrammed ecu in the e46. Crank sensor gave a reading and didn't show a fault so I'm going to rule that out for the moment
MSS54 is e46's ecu and MSS54HP is the e36's ecu.
E36 with MSS54HP:
Won't start - No Fuel no spark no injector pulse and throttle actuator is not moving and the following codes:
E46 with MSS54HP:
Starts but is in limp mode and is difficult to rev but throttle actuator is moving with following codes:
E46 with MSS54:
Starts as normal with the following codes:
Edit: didn't take a picture of this as there was nothing other than a throttle pedal code
I also was in contact with the guy that did the ECU. I'm not familiar with what goes on in the background with editing the BIN files/Hex code or whatever its referred to as but he says he has made changes so that EWS rolling code is no longer required to match between the ECU/DME and the EWS module. I think this means that I will need an EWS module to feed pin 33 of my x60004.
That's really where I'm at but I think I'm close to getting the thing to start.

- Is there a way that the DME can be programmed to not have any signal to x60004 or that I could put positive or negative to pin 33 to fufil the DME's need for a signal from EWS?
- Is the DME pin 33 looking for something more complex than a simple positive or negative to start the car that can't be replicated with a couple of relays? (I'm miserable and don't want to buy an EWS unit if I can avoid it and I don't exactly want one either from a point of view of failure/reliability)
