Per the AEM engineers, they have NEVER installed their system in a Crossfire or MB SLK320 /32 and do not know if the system will work with this car... So, do NOT listen to people who say that it's a viable product for the Crossfire until it has been installed and tested...
And this goes for the poster of this ...

Do not post information on this site that you are not 100% sure will work with the Crossfire... AEM does not support the Bosch ME 2.8 software and they will not guarantee that the system will work with the car...
