Bosch TMAP Sensor

The Bosch TMAP Sensor is a high-precision, dual-function sensor designed to read both manifold absolute pressure (MAP) and intake air temperature (IAT) in a single compact unit. This makes it an essential component for forced induction builds where accurate data input is crucial for optimal engine performance.

Whether you’re running a MoTeC, Haltech, Syvecs, or another standalone ECU, the Bosch TMAP integrates seamlessly into your system and enables real-time fuel and boost adjustment based on both pressure and temperature readings.

While stock ECUs typically don’t support external TMAP sensors without modification, this sensor is plug-and-play with most standalone management systems when paired with the correct wiring harness or adapter. It’s also designed to mount cleanly using the optional T1 TMAP Bung (sold separately).

Key Features of Bosch TMAP Sensor

• 2-in-1 Sensor: Combines manifold pressure (MAP) and intake air temperature (IAT)
• High Accuracy: Reliable under extreme boost, vibration, and typical engine bay temperatures
• Compact Design: Saves space in tight engine bays
• Motorsport Ready: Used in drag, time attack, and street builds
• Sensor Range Options: Available in both 3-bar and 4-bar variants

Base Specifications of TMAP Sensor

• Bosch OE sensor with dual MAP + IAT output
