This upgraded MapDaddy 4-Bar MAP Sensor module features both a high-boost 4-bar MAP sensor and a separate 1-bar barometric pressure sensor for real-time barometric correction—perfect for accurate fueling even in changing altitudes. Ideal for turbocharged or supercharged builds that demand precision under pressure.

New Version Upgrade Highlights:

  • 4-Bar MAP Sensor (handles up to ~44 PSI absolute)

  • 1-Bar Barometric Pressure Sensor (real-time altitude correction)

  • Improved barometric resolution for more accurate fueling

  • Fully supported by MS1, MS2, and MS3 firmware

    • MS2 & MS3 can use the second sensor for live baro correction

Installation Overview:

This unit solders directly into the standard MAP sensor location (replacing the MPX4250) and aligns perfectly with your case’s vacuum port.

  • Includes washer for bulkhead seal on PCBv3-style endplates

  • For MS2/MS3: Wire barometric sensor output to JS5 (V3.0/V3.57) or X7 (V2.2)

  • For MS1: Barometric correction wire is not used

🛠️ Requires ~0.5" of clearance between PCB and case cover. Compatible with all DIYAutoTune cases shipped since early 2006. Older rectangular-endplate cases may not fit.

What's Included:

  • MapDaddy 4-bar/1-bar sensor board
