CL203 Sportcoupé 200 Kompressor (M111)
M111 230K bigger crankshaft pulley - no power gain
Hey, maybe someone can help me out:
We've fitted a bigger crankshaft pulley (22cm) to my 2001 CL203 Sportcoupé with the 2.3L M111 Supercharger Engine to get some extra boost and performance.
I've measured times with Dragy before and after and they don't differ at all - performance seems totally unchanged.
We've checked all hoses etc.
Is there anything we could have missed? I've read everywhere an ECU tuning ist NOT needed.
Also the European version of the car doesnt' seem to have a boost sensor, it still reads 0,5 bar maximum with Torque (as before).

Disonnected the battery, wait 1/2 hour. Reconnect. ECU will adapt to new boost levels over the next couple hundred miles or so.
Maybe you'll see something then?

Is your Recirculating Flap whatever it's called functioning?
There is a procedure for reseting it around here somewhere.
