Air filter and the Paper above
I just got my ecu back from Cory. I'am changing the air filters out. What is the paper looking filter in the top of the housing and do I leave it in? I need this ASAP please.

What have I done now? has someone played a bad joke on the old man? I changed the filters and removed the charcoal paper filters. Car is running fine. Took the with shopping and a friend of mine for a ride. Got in it a little. On the way home the check engine light came on. Oil is OK. Should I have left the charcoal in? I have no idea what to check outside of what I've done. The ecu went in with ease. Any Ideas folks?

the filters might not be sitting in right. i would remove them, then reinstall them and hand tighten every screw, then tighten all the screw diagonally. Should solve the problem

from what I have read.. 2 things to check
1 - the seating of the filters (removing charcoal should not set off the CEL)
2 - maybe you need to call cory about the ECU tune (which I also doubt)

Sorry to hear your having issues, but lots of us have removed the charcoals with no issues at all.
but we all did what I have instructed you to do, I know all I did was pull it out

Lots of ppl have had success but there are also others who have had CELs right after putting in K&Ns and/or removing the charcoal filters. It's almost a moot point coz you're gaining so little in messing with the air box. Out on the street, even your butt dyno won't be able to tell the difference.

Haha...I think that you and I are very similar in our ownership...we will do some small things to the C63 to enhance it here and there but won't go ape **** and redo the entire car...I think the car as designed is a perfect piece of engineering and salute those that take it a step higher in performance...

Also weird thing was that my car only came with one charcoal filter...

So my theory that removing charcoals will not cause CEL is pretty sound....
