BMW E46 M3 S54 CSL MAP Sensor Conversion Kit

The OE BMW CSL software uses a MAP sensor to help determine engine load. Since the OE rail is no longer available and is extremely expensive on the secondhand market, we have designed a completely new CSL MAP sensor kit that has many unique features not seen on other S54 kits.

• CNC’d in USA
• Tumbled and clear anodized for long lasting finish protection
• NEW Bosch MAP sensor is included – THE SAME SCALING IS USED AS THE CSL FIRMWARE
• Viton o-rings
• Stainless steel hardware
• TEFZEL motorsport wiring in OE colors!
• Factory pre-terminated wiring so it is plug and play into the ECU
• Completely reversible, no hardware modification needed to your existing rail
• Installs in under 45 minutes

Requires full BDM of CSL firmware onto MSS54HP DME.
