Does anyone know how to give a proper vehicle speed signal into m52 dme obd2?
I give signal from cluster but the stock e36 m52 gets signal from abs/dsc.
The abs has 48 pulses and the cluster has 9 pulses
48/9=5.333
When i get live data from dme the speed signal is 5.333 times less than speedometer speed.

If you're talking about the hall sensor in the diff requirement to the engine ECU to retain full RPM usage then i can help. I've got two M52 Siemens ECUs that are mapped for M50 manifolds, EWS disabled and speed signal requirement disabled as well.
These are left over’s from my drift car, and from a customer’s car when i was going conversions for people.
If you want to use your ECU then EndTuning can do it for you or maybe Dan can do it for you ^

To the speedo in the instrument cluster? I'm not sure, I don't have one in my E21 the drive was mechanical from the gearbox so I just had it disabled in the ecu. I would have thought all the trigger wheels are the same but without cracking open an e36 and e30 diff I couldn't say. Maybe the sensors are slightly different or maybe the wiring needs looking at? I'm clutching at straws to be honest...
