I have a 1992 bmw 325i with the m50b25 engine.
I have always really admired these cars, and I stumbled upon this one in a trade offer for a custom bobber I built.
now then, The car has always seemed a little sluggish in the lower rpm range, but i didnt really think anything of it.
Yesterday it started missing really bad, and upon investigation i found that the #4 cylinder coil is not sparking. i hooked up a small light bulb to the coil plug and ran the car, and it wasnt getting a signal to fire from the emc.
I then referenced the manual and found that pin #50 on the DME is the signal for that coil. i checked continuity between #50 on the ecu plug and the wire on the coil plug and it is making continuity.
That leads me to believe that my DME has taken a crap on me.
I know from research, and from buying a few parts that 92 was the only year e36 with the non-vanos m50b25 engine, and after looking at my dme, something doesnt add up...
On the upper right side of the lower tag there appears to be a date (i think) and it says 11.01.96, and it is also a silver label tag, which from other research i know is a EWC ecu. i didnt think (and correct me if im wrong) that ewc was introduced until 93?
anywho, does anyone know the CORRECT DME that i need for this car?
I have included a picture of my DME.
Thanks in advance!
