Convert your MSS54 or MSS54HP to full OE CSL spec with this conversion. We add the necessary capacitors and H-Bridge to the boards so that all S54 CSL functionality is retained including the stock OE motorized intake flap if desired. The full CSL firmware is BDM’d directly onto your ECU. This is not a hamstrung cobbled together firmware, this is a genuine CSL full binary. MSS54 NON HP cost $255 to upgrade to genuine HP DME’s.
The CSL firmware is by far the most proper software for anyone looking to install the CSL airbox, install ITB Stack kits, or to delete the MAF.
