AEM Electronics 30-2130-75 MAP Sensor 5 Bar (75 PSIa, Stainless Steel) – Turbo Pressure Control for Programmable ECUs

The AEM 30-2130-75 is a 5 Bar MAP (Manifold Absolute Pressure) sensor designed for turbocharged or supercharged engines that require precise pressure measurement in high-performance applications. Made from marine-grade stainless steel, it delivers accurate real-time readings for advanced ECU tuning, allowing you to adjust fuel and ignition maps with complete reliability.

Features

• 304L and 316L stainless steel body – Full resistance to automotive fluids, corrosion, and extreme temperatures
• ±0.5% full-scale accuracy – Ultra-accurate data for perfect tuning in any condition
• Response time under 1ms – Instant reaction to pressure changes for optimal engine control
• Ceramic sensing technology – Greater thermal stability and vibration resistance than conventional sensors
• 360° welded wetted area – Eliminates any risk of air leakage under high pressure

Technical specifications

• Measurement range: 0 to 5 Bar Absolute (0 to 75 PSIa)
• Boost reading capacity: Up to 4 Bar (58 PSI)
• Output signal: Linear analog 0.5 – 4.5V DC
• Supply voltage: 5V DC
• Connection thread: 1/8" NPT Male
• Temperature range: -40°C to +105°C
• Burst pressure: 500 PSI
• Weight: Less than 85 grams
• Electrical connection: Sealed connector with 30cm wires (Red = +5V, Black = Ground, Green = Signal)

Compatibility

This sensor is universal and compatible with any aftermarket ECU that accepts a 5V analog input, including:

• ECUs: AEM Infinity, Haltech, Link ECU, MoTeC, Syvecs, ECUMaster, MaxxECU
• Popular vehicles: Subaru WRX/STI, Mitsubishi Lancer Evolution, turbo Honda (B/K/D series), Nissan Silvia/Skyline, and custom turbo or supercharged projects

Why choose the AEM 30-2130-75

Compared to budget plastic or brass sensors, the 30-2130-75 offers a one-piece stainless steel construction with no joints that can fail. Its 5 Bar range provides higher resolution than 7 Bar sensors at the same voltage, allowing much finer tuning in the typical 0-4 Bar boost range. Ideal for competition and demanding builds.

Kit contents

• MAP sensor 30-2130-75
• Sealed connector with 30cm wires
• 1/8" NPT to -4AN adapter
• 1/8" NPT to 3/16" barb adapter

Frequently asked questions

• How much boost pressure can it measure? Up to 4 Bar of boost (plus 1 Bar atmospheric = 5 Bar absolute).
• Can I replace a 3 or 4 Bar sensor? Yes, it is compatible and offers greater accuracy in high boost ranges.
• Does it require special calibration? Simply program your ECU with the linear 0.5-4.5V curve corresponding to the 0-5 Bar range.
