      Just to clarify, a flap is not included, right? Just ECU?

        a?

        I am confused haha.

        The listing is for a full CSL spec ECU. That is able to drive the OEM flap as well, which is often skipped in conversions.

        To anyone reading this shoot me an offer, looking to move this thing.

            Interested, but have kind of a dumb question. Is the DME pictured the one that's for sale? The pictured DME appears to be an MSS54 but the ad lists it as an MSS54HP.

              It has been converted. I have an actual MSS54 HP CSL case, I could install it in that case if that bothers you haha.
