AEM 3.5 Bar Stainless MAP Sensor Kit, 1/8 NPT - 30-2130-50

The AEM 30-2130-50 is a 3.5 bar (50 psia) manifold absolute pressure (MAP) sensor with a stainless steel body, a 1/8 inch NPT male thread and a weatherproof 3-pin connector.

It reads from full vacuum up to about 35 psi of boost at sea level. Running more boost? Use the 5 bar stainless MAP sensor 30-2130-75.

Fitment and requirements

• Fits any engine where you can add a 1/8 inch NPT port or a hose connection to intake manifold pressure
• Needs an ECU, data logger or gauge with a spare analog input that reads 0.5-4.5V and supplies a regulated 5V sensor reference
• Your ECU or software must accept a custom linear sensor scaling (see installation below)

What it does

• Measures 0 to 50 psi absolute (3.5 bar)
• Linear 0.5-4.5V output
• Accuracy +/- 1 percent of full scale (AEM rating)
• 304L stainless body with 316L wetted parts, sealed against fuel and oil
• Operating range -40 to 105 C
• Connector kit, -4 AN adapter and 3/16 inch hose barb included

What is in the box

• 3.5 bar MAP sensor
• 3-pin connector and pins
• 1/8 NPT to -4 AN adapter
• 3/16 inch hose barb

Installation and limitations

Connect the sensor signal to your input, sensor ground to sensor ground and sensor power to the ECU or logger +5V reference. Plumb it to manifold pressure and mount it away from direct exhaust heat.

Scaling from AEM's datasheet: 0.5V = -14.7 psi (full vacuum) and 4.5V = 35.3 psi of boost, linear. Boost in psi = 12.5 x volts - 20.95. Full details: AEM pressure sensor instructions (PDF) and AEM 30-2130-50 datasheet (PDF).

Frequently asked questions

How much boost can the AEM 30-2130-50 measure?

About 35 psi of boost at sea level. The sensor is rated 50 psi absolute; subtract roughly 14.7 psi of sea-level atmospheric pressure. At higher altitude the boost ceiling is slightly higher.

Will the AEM 30-2130-50 work with my ECU or logger?

Yes if the device has a spare 0.5-4.5V analog input, a 5V sensor supply, and lets you enter a custom linear scaling. Use the transfer function above.

Can I log the AEM 30-2130-50 with an HP Tuners MPVI4?

Not on its own. The MPVI4 reads external sensors through HP Tuners' PROLINK+ cable (sold separately), and the sensor still needs a 5V supply. Enter AEM's scaling in VCM Scanner. See the HP Tuners MPVI4.
