MAP Sensor Scaling & Calibration
Modern engines rely on Manifold Absolute Pressure (MAP) sensors to measure the amount of air entering the intake manifold. When you upgrade turbochargers, install performance intakes, or remap your ECU, the factory MAP sensor range can become inadequate, resulting in inaccurate readings and inconsistent performance. MAP sensor scaling (also called “MAP sensor recalibration”) ensures your ECU interprets boost and airflow correctly after modifications, unlocking the full potential of your upgrades.
When boost pressure exceeds the limits of the factory MAP sensor, the ECU “sees” less air than is actually entering the engine. This can lead to fueling errors, boost cut, and reduced power output. Proper MAP sensor calibration aligns the sensor voltage range with the new pressure limits so the ECU knows exactly what’s happening inside the manifold. This is essential for safe, reliable, and powerful engine tuning—especially on turbocharged petrol and diesel engines found in performance cars, vans, and commercial vehicles.
Proper MAP sensor scaling delivers more than just accurate readings – it’s the foundation for reliable, high-performance tuning. By recalibrating your manifold absolute pressure sensor after turbo or intake upgrades, your ECU receives precise boost data, allowing for optimised fuel delivery, safer air-fuel ratios and smoother throttle response. This process protects pistons, turbos and injectors under load while unlocking the full gains from ECU remapping and performance parts.
