2007 M8 with Aerocharger 53, Dobeck Box
950km
Symptoms:
-Sled starts and runs on one cylinder at high idle (3200rpm +/-)
-Depending on the amount of fuel pressure (tweaked by partially clamping fuel return line) , sled will alternate which side is running, as indicated by Digitron & IR thermometer. Generally runs terribly and rpms will climb randomly while idling.
Things that have been checked
- compression
- power valves (cleaned and adjusted)
- reeds (replaced with new)
- fuel pump pressure and flow
- regulator pressure tweaked between 38 psi to 44psi
- ECU replaced
- visual inspection of electrical wiring
- coils
- stator
- spark plugs
- Dobeck box unplugged
Any help is greatly appreciated.
