I admire everyone's effort to get rid of the CEL. Although I would love mine to not be there on my dash with my catless downpipes, I gave up a long time ago on trying to get rid of it before a proper ECU tune comes out. Like Nate said, the S63tu DME's are too advanced. We will not be able to trick it. I stuck a black sticker over the CEL on my instrument cluster and I tell you I always forget that I even have a CEL until I see you guys bring them up on threads like these. Like I've been saying since DAY 1, wait until ESS comes out with their tune. They will remove the CEL and the Top Speed Limiter, it's what they do!
