AEM Electronics 30-2131-75 5 Bar (75 PSI) MAP Sensor Kit – High Performance for Turbo and Supercharged Engines

The AEM 30-2131-75 MAP sensor is a high-precision component designed to measure intake manifold pressure in turbocharged or supercharged engines. With a range up to 5 bar (75 PSI), it monitors extreme boost levels in race-prepped engines, drag racing builds, or high-performance street cars.

Features

• 5 bar (75 PSI) range: measures high turbo pressures without signal loss or sensor saturation.
• Welded brass body: resists corrosion, vibration, and high engine bay temperatures.
• ±3% accuracy: provides reliable readings so the ECU can properly adjust fuel injection and ignition timing.
• Automotive-grade seal: 360-degree weld, protected against oil, fuel, and other fluids.
• Includes connector and terminals: ready to install on any programmable ECU.

Technical specifications

• Part number: AEM 30-2131-75
• Pressure range: 0 to 75 PSI (5 bar)
• Voltage output: 0.5 to 4.5 V
• Body material: brass
• Accuracy: ±3% full scale
• Thread: 1/8" NPT

Compatibility

This sensor is universal and works with most standalone ECUs on the market, including AEM Infinity, AEM Series 2, Haltech, Link ECU, Motec, and MaxxECU. Primarily used in:

• Race cars (circuit, drag racing, time attack).
• High-boost turbo or supercharger builds (above 1.5 bar).
• Engines with sequential injection managed by standalone ECU.

Note: generally not compatible with factory ECUs that don't allow voltage curve calibration. Verify your ECU supports 5 bar MAP sensors before installation.

Why choose AEM Electronics

While standard MAP sensors (1, 2, or 3 bar) max out on high-performance builds, the AEM 5 bar is built to handle thermal stress and vibration without losing accuracy. Its welded brass construction ensures durability and stable signal, preventing fueling errors that could damage the engine.

FAQ

• Can I install this on my car with stock ECU? Typically no, unless your ECU allows voltage curve calibration. Recommended for standalone ECUs.
• Can it measure oil or fuel pressure? Yes, its sealed design makes it compatible with engine liquids and gases.
• What's included in the kit? 5 bar brass sensor with 1/8" NPT thread, connector, and mating terminals.
