MSS54 / MSS54HP Full CSL Hardware/Firmware Conversion

$235.00

Convert your MSS54 or MSS54HP to run the full BMW CSL software. This conversion also allows for use of the OEM CSL air flap and a MAP sensor when you use the CSL air intake box. This software is the most superior base for tuning your S54 without a MAF. Ideal for CSL airbox, ITB Stack kits, or simply just MAF deletes.

MSS54 NON HP cost and additional $255 to upgrade to genuine HP DME’s.

Turn around time is 24hrs on all converted DME’s!

Description

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. ISN’s are reset so EWS needs to be reset or deleted. 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 and additional $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.
