M271 Boost cut, Restart car= engine check light
Hi
Ive got a clk200 using the M271 engine.
Ive upped the engine pulley(fabricated shud b abt same as the c230) and supercharger pulley (kleeman) and have gotten 1 bar of boost, however my ecu has been giving me boost cuts and when i restart the car, im getting an engine check light.
Would anyone know a solution to this problem?
My car has been custom tunned via obd2 port. I doubt its the tunning part. Its AF ratios are quite on the safe side and not much advance of the ignition.
Im also using a 1 step colder iridium plug. Heat range 7. Ive got the kleeman extractor and HKS drop in filter.
It gives pretty darn good power but the torque and hp drops after 4.6k rpm.
