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

The AEM 30-2131-75 MAP sensor is a high-precision component designed to measure intake pressures in turbocharged or supercharged engines. With a range of up to 5 bar (75 PSI), it allows monitoring of extreme boost levels in competition builds, drag racing, or high-performance vehicles.

Key features

• 5 bar (75 PSI) range: measures high turbo pressures without signal loss or sensor saturation.
• Welded brass body: resistant to corrosion, vibrations, and high engine temperatures.
• ±3% accuracy: guarantees reliable readings so the ECU correctly adjusts fuel injection and ignition timing.
• Automotive-grade sealing: 360-degree welding, protected against oils, fuels, and other fluids.
• Includes connector and terminals: ready to install in any programmable ECU.

Technical specifications

• Reference: 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% of full scale
• Thread: 1/8" NPT

Compatibility

This sensor is universal and works with most programmable ECUs on the market, such as AEM Infinity, AEM Series 2, Haltech, Link ECU, Motec, or MaxxECU. It is primarily used in:

• Competition vehicles (circuit, drag racing, time attack).
• Builds with high-boost turbo or supercharger (over 1.5 bar).
• Engines with sequential injection managed by a standalone ECU.

Note: it is usually not compatible with stock ECUs that do not allow calibration of the voltage scale. Check that your ECU supports 5 bar MAP sensors before installation.

Why choose AEM Electronics

While standard MAP sensors (1, 2, or 3 bar) saturate in high-performance builds, the AEM 5 bar is designed to withstand thermal stress and vibrations without losing accuracy. Its welded brass construction guarantees durability and a stable signal, preventing mixture faults that could damage the engine.

Frequently asked questions

• Can I install it in my car with a stock ECU? Usually not, unless your ECU allows calibration of the voltage curve. It is recommended for programmable ECUs.
• Can it be used to measure oil or fuel pressure? Yes, its sealed design makes it compatible with engine fluids and gases.
• What does the kit include? A 5 bar brass sensor with 1/8" NPT thread, connector, and mating terminals.
