To provide closed-loop boost control at absolute pressure levels above 2.5 bar, many aftermarket turbocharger kits utilize an OEM Bosch 3-bar MAP sensor. This sensor is ONLY required and applicable where specified.
Altering the ECU to understand the engine is equipped with a 3-bar MAP sensor is a trivial task. The sensor and proper calibration settings come standard on many factory VAG vehicles, but even these vehicles only provide proper closed loop boost control up to 2.5-bar absolute.
This sensor cannot be installed without accompanying 3-Bar map sensor software. Without appropriate software, the engine will not function properly. We are not responsible for any damage caused by improper sensor selection for your application.
