This means that without the signal from the auto the pcu will never engage the supercharger clutch and you run a low compression n/a motor. To solve this you need to find someone who not only has the ability to manipulate mb computers but also has a beta program for the 3.2.
A flywheel from the 2006/07 c230 should work, it has the same bolt pattern at the AMG crank in the SRT. Talk to Rcompart, he might be able to help with programming, He is the XfireECU God round these parts. He is a good dude
