Shame how this ended up. At least you should end up with a working car

Hey sorry, I've been strapped to an IV pole most of the day... I'll text you tomorrow afternoon/eveningNew parts installed this morning. Still won't fire. Not exactly sure what my issue is
Doesn't look like Bimmerfest is happening this year if I can't get it to turn over.
Anyone want to remote guide me for some coding. I'm already set up. Sent a text to Terra, but he must be busy.

No you don't...
And EWS doesn't care if its manual or not. Every US manual is detected as an auto by PASoft. All that switch does is enable/disable the clutch interlock
Also manual vs auto doesn't make a difference for the dme. Same software regardless. Clearing adaptions resets the module to manual if a tranny computer isn't present.

That's because that's a Euro car, which don't have clutch interlocks. US cars do, and it sends the same signal to the EWS that the auto would. Unless he miswired the clutch sensor, this should not be an issue.
Do not need to do anything with PASoft to change that setting anyway. Change PARK/NEUTRAL_EINGANG to nicht_aktiv in NCS Expert. Exact same effect as telling PASoft the car is a manual.
Also if his car cranks without starting, it's not an interlock issue. If the car doesn't crank at all, then it could be.
Not an issue in his case. He bridged the pins under the 20-pin connector so that all K-lines go to pin 7. He would not be able to talk to the EWS module at all if this were not the case.
BMW Scanner is not necessary. I've synchronized DMEs and EWS countless times with INPA.

Just to be clear, it's cranking, but not firing, correct? I assume your fuel pump is priming? I am surprised you don't have any codes. It should throw an "impossible to start" code if it's failing to start. At this point you should test for spark
Also, check the EWS module itself for error codes.

I don't quite understand. Ms42 and 43 use the same O2 sensors and same relays.

^ looks like you can replicate the same thing by simply splicing the extra wires. IIRC those extra wires are signals which originally went directly to the MS42 and then to the cluster from the DME. With the MS43, those signals go to the cluster, and then reach the DME over CAN.
Which gives me a good idea -- maybe we need to recode his cluster with MS43 settings so that it broadcasts that info over the CAN bus.

I don't remember all of them, but stuff like oil pressure, oil level, battery, and starter signal.

I'm stumped. EWS is sync'd, no codes are being thrown (except for exhaust gas flap), the CAN bus is functional, and all sensors seem to be getting the right signals. I want to say that at this point the car should be diagnosed as if it's a factory E46 that isn't starting.

This is what the WDS says
MS43
MS42
edit:
Here's the diagram for X6326 (unloader relay) on the MS42:

Basically it seems like they're the same relay, except it goes to the first ignition coil on the MS42, and injectors on MS43.
And the ignition diagram from the MS43:

Some additives may have degraded, but it should still start with old fuel, maybe just run badly afterwards. I had a tractor with 3 year old gas that started right up.

Okay so definitely some kind of fueling problem. If you can hear the fuel pump priming, then check the pressure at the pressure rail. If it's less than 50psi, either the fuel pump is crapping out, or the filter is clogged. If pressure is good, then there's probably something wrong with the wiring of the injectors.

I don't know about that. TDC and BDC will occur at the same point regardless of displacement. The total distance the cylinders move is less, but the angles don't change. At the most it might be squirting a bit more fuel than it needs to, but that shouldn't prevent it from starting.
You could always try your original 328 injectors with a 325 tune... but I don't think displacement is the problem
Short Stroke vs Long Stroke
Yeah -- even a few seconds of data could be valuable at this point

testo. It's been somewhat recently updated to have direcct access to some ECUs (no EDIABAS in between). Seems like the direct access requires the engine to actually be running though

We know the engine is getting spark and you did check to make sure the relay is clicking, right? Did you ever get around to verifying fuel pressure?

Can you take a picture of it? It's definitely a possibility, but I would think that if it's holding pressure and isn't kinked, fuel should still get to all the injectors.

Search the WDS. It's in there
