3-Bar Map Sensor

The 3-Bar Map Sensor from MSD Ignition is a critical component for tuning and calibrating fuel-injected engines. It is designed for builders and mechanics who require precise measurements for optimal engine performance. This sensor is particularly useful for those working with forced-induction setups or diagnosing fuel mixture issues.

This manifold absolute pressure sensor measures pressure across a 3-bar range (approximately 43.5 psi), providing enhanced accuracy compared to standard 1-bar sensors. Its design ensures stable signal output even under thermal cycling and vibration, making it robust enough for harsh engine environments. The compact size of 3.4 x 2.35 x 5.7 inches and lightweight profile of 0.2 lbs facilitate installation, although some applications may require custom mounting solutions.

Performance enthusiasts and technicians utilizing custom ECU programming or standalone engine management systems will benefit from the precise data this sensor provides. It is particularly advantageous in turbocharged and supercharged applications where stock sensors may not suffice. This sensor is an excellent choice for anyone looking to enhance their engine's performance and reliability.
