AEM 5 BAR MAP or 75 PSIA Stainless Steel Sensor Kit

AEM 5 BAR (75 PSIA) Stainless Steel MAP Sensor Kit | Part # 30-2130-75

Upgrade your high-boost build with the AEM 5 BAR / 75 PSIA Stainless Steel MAP Sensor Kit. Offers 1% accuracy, rugged construction, and includes full adapter kit.

The AEM 5 BAR / 75 PSIA Stainless Steel MAP Sensor Kit (Part # 30-2130-75) provides extreme precision, durability, and fast response times for high-performance forced induction engines. Designed specifically for high-boost turbocharger and supercharger applications, this absolute pressure sensor accurate to within $\pm 1\%$ across a wide operating temperature range ($-40^\circ\text{C}$ to $105^\circ\text{C}$).

Because it measures absolute pressure (PSIa), it measures both vacuum and positive manifold pressure (up to $\approx 60.3\text{ PSI}$ of boost relative to sea level) with standard linear $0.5\text{V}$ to $4.5\text{V}$ output scaling. Constructed with $304\text{L}$ and $316\text{L}$ stainless steel wetted materials and a 360-degree welded body, it resists degradation from fuel vapors, harsh automotive fluids, high heat, and intense engine vibration. The kit comes fully equipped with standard mounting threads ($1/8\text{" NPT}$), adapter fittings ($-4\text{ AN}$ and $3/16\text{"}$ barb), and a weatherproof mating connector with leads for straightforward installation into any standalone ECU or engine management system.

Best Uses

1. High-Boost Turbocharged & Supercharged Engines: Ideal for forced-induction builds requiring reliable pressure monitoring up to 60.3 PSI of boost.
2. Stand-Alone Engine Management Tuning: Provides high-speed manifold pressure inputs to aftermarket ECUs (e.g., AEM, Haltech, MotEC, Link, Megasquirt).
3. Motorsport Data Logging: Accurately logs real-time manifold absolute pressure and vacuum data during track, drag, or dyno runs.
4. Extreme Harsh Environment Applications: Excellent for engine bays exposed to high vibration, temperature swings, oil mist, or fuel vapors.

Features

1. 5 BAR / 75 PSIA Measurement Range: Measures absolute pressure from -14.7 PSI (vacuum) up to 60.3 PSI (boost).
2. 304L & 316L Stainless Steel Housing: Highly durable body resistant to corrosion, heat, and automotive fluids.
3. 0.5V to 4.5V Linear Output: Outputs a standardized ratiometric analog voltage signal for straight-forward calibration with any compatible ECU.
4. Fast < 1ms Response Time: Delivers lightning-fast pressure readings to ensure precise fuel, ignition, and boost control.
5. Complete Installation Hardware Kit: Includes 1/8" NPT male threads, a -4 AN adapter, a 3/16" barb adapter, and a weatherproof mating connector kit.

Benefits

1. High Engine Protection & Tuning Accuracy: Features <0.5% full-scale accuracy for reliable air-fuel ratios and safe engine calibration under high boost.
2. Maximum Durability & Chemical Resistance: Unlike standard plastic or brass sensors, the stainless steel construction prevents leaks and survives harsh chemical exposure.
3. Plug-and-Play ECU Compatibility: The 0.5V–4.5V signal integrates effortlessly into virtually all major standalone ECUs and data loggers.
4. Vibration & Pressure Spike Resistance: Built to handle high-vibration engine environments (up to 20G) and features a high burst pressure rating.
5. Flexible Plumbing Options: The included NPT, hose barb, and AN adapters allow for direct-manifold mounting or remote mounting via lines.
