I have a complete standalone setup for running a S65 V8 outside of an E90, or could be used as a spare if you don't want to touch your OEM DME.
Came out of Randy Mueller’s ( aka EPIC owner) S65 powered E46 M3. ( we moved the car over to Motec)
Includes:
- MSS60 DME
- security module
- key
- start switch
- EPIC ECI interface mated to this DME
- DCAN cable
happy to ship for shipping expenses.
Cheers!
