The MAP sensor or the Manifold Absolute Pressure sensor is a sensor that measures the changes in vacuum pressure and sends a signal to the ECU. The ECU then calculates the engine load and calculates the fuel and timing. These have the higher reading of 4 BAR, as opposed to the standard 3 or 2.5 BAR, meaning higher boost pressures can safely be used. Please only fit on the recommendation of your Tuning Specialist, as incorrect replacement may damage your engine.
Max “Usable” boost PSI 2.5 bar sensor…20 psi
Max “Usable” boost PSI 3.1 bar sensor ..28 psi
Max “Usable” boost PSI 4.0 bar sensor…42 psi
When most modern turbos, especially Hybrids can operate at +30 PSI the need for a 4 bar sensor is a must! Up until now the only direct upgrade map sensor was a 3.1 bar option.
We have designed, manufactured a CNC billet anodised adapter block to allow the VW 4 bar sensor (narrow probe) to be directly bolted to the original MAP sensor fitting point.
Will blend in and make the new 4 bar sensor look factory fitted, Built to last, Nitrile sealing washers that are oil resistant, comes with stainless bolts and washers.
