bro g0dspeed, I am located in Kuching where there are not many ppl who are expertise in bmw conversions. so far in kch other than mine currently going on, only xsjado has gone the m40-m42 way.

My case is quite different. i bought the engine without the ews module. second issue is with the wiring as the wiring loom was messy when it came (without the x20 connector). so im worried that maybe some wiring are not wired up properly.

so im now trying to resolve the problem between getting the right ecu to bypass ews and proper wiring connection. Need some input tho cos i was told that u can just use a non-ews (pre 94) to bypass the ews system. question is do u also need the non-ews wiring harness?

i have yet to bring to car for diagnostics as i currently have no time.sigh.

Why don't your mech try to build the harness from scratch? My mech did. For ecu pinout and electrical diagram you can refer to e36 bentley manual. I have the softcopy if you need it. Let me know if you need any bits from the wiring loom as I have plenty lying around.

I do have the bentley manual. for the wiring, my mech might look for a wireman to do it so will see how that goes..as the current one is done by a 'not certified wireman' but done strictly according to the wiring diagram.so its either some wiring mistakes or its purely the EWS being a bitch. prior to that i think the best bet is to diagnose the damn thing first. so will be arranging for towing for diagnostics by first week of march. wish me luck guys.
