Apexi 3-Bar MAP Sensor + Solenoid Valve Harness | 5-Pin Connector | High-Boost Turbo Applications | Apexi Power FC / AVC-R Compatible

The Apexi 3-Bar MAP Sensor with 5-Pin Solenoid Valve Harness (49C-A003) is a high-pressure MAP (Manifold Absolute Pressure) sensor and wiring harness assembly designed for use with Apexi's Power FC engine management system and AVC-R boost controller — providing accurate manifold pressure measurement across the full boost range of high-boost turbocharged applications. The 3-bar rating allows the sensor to measure absolute pressures up to approximately 3 bar (44 psi absolute / approximately 29 psi boost above atmospheric) — correct for high-boost turbo builds that exceed the measurement range of a standard 2-bar MAP sensor. The 5-pin harness connects the MAP sensor to the solenoid valve in the Apexi boost control system for a complete, plug-and-play installation. Apexi is one of the most respected Japanese performance electronics brands in the world — known for the Power FC engine management system, AVC-R boost controller, and a wide range of performance electronics for Japanese performance platforms.

Key Features:

• 3-bar MAP sensor — measures absolute manifold pressure up to approximately 3 bar (44 psi absolute) — correct for high-boost turbo applications running approximately 29 psi (2 bar) boost or less above atmospheric pressure
• 5-pin solenoid valve harness — 5-pin connector harness for connection to the solenoid valve in the Apexi boost control system — plug-and-play installation with compatible Apexi systems
• Power FC compatible — correct MAP sensor specification for use with the Apexi Power FC engine management system on high-boost applications where the standard MAP sensor's range is insufficient
• AVC-R compatible — correct for use with the Apexi AVC-R boost controller system
• High-boost turbo applications — the 3-bar rating extends the MAP sensor's measurement range beyond the standard 2-bar sensor — correct for builds targeting boost levels above approximately 14-15 psi where a 2-bar sensor approaches its measurement limit
• Apexi quality — manufactured by Apexi, one of the most respected Japanese performance electronics brands in the world

3-Bar MAP Sensor — Why It Matters:

A MAP sensor measures the absolute pressure in the intake manifold — a critical input for the engine management system to calculate the correct fuel and ignition maps. The "bar" rating of a MAP sensor defines its maximum measurement range:

• 2-bar MAP sensor: Measures up to approximately 2 bar absolute (approximately 14.5 psi boost above atmospheric at sea level). Correct for mild to moderate boost applications.
• 3-bar MAP sensor: Measures up to approximately 3 bar absolute (approximately 29 psi boost above atmospheric at sea level). Correct for high-boost applications where the 2-bar sensor's range is insufficient.

When a MAP sensor is used beyond its measurement range, the engine management system receives a clipped, inaccurate pressure signal — resulting in incorrect fuel and ignition calculations that can cause lean conditions, knock, and engine damage. For high-boost Power FC and AVC-R builds targeting boost levels above approximately 14-15 psi, the Apexi 3-bar MAP sensor is the correct upgrade.

Apexi Power FC & AVC-R — System Context:

The Apexi Power FC is a standalone engine management system (ECU) used on a wide range of Japanese performance platforms — replacing the factory ECU with a fully programmable unit that supports custom fuel, ignition, and boost control maps. The AVC-R is Apexi's electronic boost controller — a solenoid-based boost control system that provides precise, programmable boost pressure control. Both systems use a MAP sensor as a primary pressure input — and both benefit from the 3-bar sensor upgrade on high-boost applications where the standard sensor's range is exceeded.

Specifications:

• Brand: Apexi
• Part Number: 49C-A003
• Sensor Type: MAP (Manifold Absolute Pressure)
• Pressure Rating: 3-bar (approximately 44 psi absolute / 29 psi boost above atmospheric)

Fitment Information:

• Universal — for use with Apexi Power FC and AVC-R systems on turbocharged applications requiring a 3-bar MAP sensor
• Note: Verify compatibility with your specific Apexi Power FC or AVC-R system version before ordering — confirm that 49C-A003 is the correct 3-bar MAP sensor and harness for your specific system. Verify that your Power FC or AVC-R system supports the 3-bar MAP sensor input and requires recalibration or map adjustment after sensor installation. Professional installation and tuning by an experienced Apexi Power FC or AVC-R specialist strongly recommended.

What's Included:

• Apexi 3-bar MAP sensor (49C-A003)
• 5-pin solenoid valve harness
• Refer to Apexi's product documentation for complete kit contents and installation instructions

Installation Notes:

• Professional installation and tuning by an experienced Apexi Power FC or AVC-R specialist strongly recommended — MAP sensor replacement on a Power FC system requires correct sensor calibration and map verification after installation
• Verify that your Power FC or AVC-R system's maps are correctly calibrated for the 3-bar sensor's output range after installation — installing a 3-bar sensor without updating the system's pressure calibration will result in incorrect pressure readings and incorrect fuel/ignition/boost control
• Verify correct connector orientation and secure harness routing before installation — the 5-pin connector must be fully seated and the harness must be routed away from heat sources and moving components

Why Apexi?
