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

The AEM 30-2130-75 is a 5 Bar MAP (Manifold Absolute Pressure) sensor designed for turbocharged or supercharged engines requiring precise pressure measurement in high-performance applications. Constructed from marine-grade stainless steel, it delivers accurate real-time readings for advanced ECU calibration, enabling reliable fuel and ignition mapping adjustments.

Features

• 304L and 316L stainless steel body – Total resistance to automotive fluids, corrosion, and extreme temperatures
• ±0.5% full-scale accuracy – Ultra-precise data for perfect mapping under 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 wet zone – Eliminates any risk of air leaks 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: 0.5 – 4.5V DC linear analog
• Supply voltage: 5V DC
• Thread connection: 1/8" NPT Male
• Temperature range: -40°C to +105°C
• Burst pressure: 500 PSI
• Weight: Under 85 grams
• Electrical connection: Weatherproof connector with 30cm leads (Red = +5V, Black = Ground, Green = Signal)

Compatibility

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

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

Why choose the AEM 30-2130-75

Compared to cheap plastic or brass sensors, the 30-2130-75 offers solid stainless steel construction with no gaskets that can fail. Its 5 Bar range provides better resolution than 7 Bar sensors over the same voltage span, allowing much finer calibration in the typical 0-4 Bar boost range. Ideal for competition and demanding builds.

• 1/8" NPT to -4AN adapter
• 1/8" NPT to 3/16" barb adapter

FAQ

• How much turbo pressure can it measure? Up to 4 Bar boost (plus 1 Bar atmospheric = 5 Bar absolute).
• Can I replace a 3 or 4 Bar sensor? Yes, it's compatible and offers better accuracy at higher boost levels.
• Does it require special calibration? Just program your ECU with the 0.5-4.5V linear curve corresponding to the 0-5 Bar range.
