Torque Solution TS-ST-829K MAP Sensor Adapter with PNP Harness Ford Fiesta ST

The Torque Solution TS-ST-829K MAP Sensor Adapter with plug-and-play harness is designed for high-boost Ford Fiesta ST applications running beyond the factory MAP sensor's limitations. This adapter allows the use of aftermarket MAP sensors like the AEM 50 PSIa unit, enabling accurate manifold pressure readings up to 35 PSI of boost on heavily modified engines.

Key Features:

• Includes plug-and-play wiring harness for simplified installation
• Allows installation of 1/8" NPT threaded MAP sensors in factory location
• Features integrated boost port for BOV or auxiliary system operation
• CNC machined aluminum construction for durability
• Installs between intake manifold and MAP sensor location
• Essential for big turbo builds exceeding 29 PSI boost levels

This kit is designed for performance enthusiasts running big turbo setups, auxiliary fuel systems, or high-boost applications where the factory 3-bar MAP sensor becomes inaccurate. The Fiesta ST uses a speed-density ECU that relies heavily on accurate MAP readings for proper fueling and engine management. When boost exceeds factory sensor limits, readings become unreliable and can cause tuning issues. This adapter solves that problem by allowing the use of higher-range sensors while maintaining proper manifold pressure measurement. Professional tuning is required after installation to calibrate the ECU for the upgraded sensor.

What's Included:

• MAP sensor adapter body
• Plug-and-play wiring harness
• Boost reference port fitting
• Installation hardware

Note: Aftermarket MAP sensor sold separately. Recommended for use with AEM 30-2130-50 (50 PSIa) MAP sensor. Professional tuning required.
