This 400 kpa map sensor can measure the boost over 1.5bar and fits in the 1.8T, 2.0L TSI and 2.0L TFSI engines. The standard sensor can not measure over 1.5bar, so if our engine is boosting higher than 1.5bar you should change to this sensor! The ECU mapping has to be changed according to the new sensor calibration! Calibration: 0,4 Volt = 412,432 4,65 Volt = 4131,200 Manufacturer Information about the manufacturer BAR-TEK BAR-TEK Motorsport GmbH Im Rauschen Auel 3, 51491 Overath-Brombach, Germany info@bar-tek.com
