The FAST Electronics Map Sensor – 3 Bar (Part Number 307009) is a precision manifold absolute pressure sensor engineered for turbocharged and supercharged engine management systems. This 3-bar MAP sensor delivers accurate manifold pressure readings up to 30 psi boost, making it ideal for forced-induction applications where real-time pressure monitoring is critical to fuel injection timing and boost control. The sensor ships complete with connector included, ready for direct installation.
The 3-bar rating specifies the maximum absolute pressure this sensor can safely measure—approximately 44 psi absolute, which translates to roughly 30 psi of boost above atmospheric pressure. This specification is essential for tuned performance engines where boost levels push into moderate territory. FAST Electronics manufactures this sensor to OEM-grade tolerances, ensuring signal accuracy that standalone engine computers and aftermarket ECUs depend on for stable air-fuel ratios and knock control. Compact dimensions (2.8 x 2 x 4.1 inches) allow flexible mounting in engine bay locations where space is limited.
Builders and tuners of turbocharged or supercharged engines—whether street cars, weekend track vehicles, or competition builds—select a 3-bar MAP sensor when boost targets exceed what factory sensors can reliably measure. It pairs with EFI systems that require analog pressure feedback for closed-loop boost management. The pre-installed connector eliminates custom wiring, reducing installation time and diagnostic complexity. Experienced engine builders recognize that accurate manifold pressure sensing directly impacts drivability, throttle response, and reliability under sustained boost.
MAP sensors are foundation components in modern forced-induction tuning. Selecting the correct pressure range—3-bar, 5-bar, or higher—depends on your target boost level and EFI platform requirements. FAST Electronics' 307009 addresses the mid-range boost segment where most street and mild racing applications operate, balancing sensor resolution with cost-effectiveness.
