i. Installation diagram
As shown above the picture, The cammus computerneed to connecttheoriginal carturbopressure sensorandintake air pressure sensor. Turbo pressure sensor(orair flow meter) generallylocates inthegas circuit which before the turbo and behind the throttle. The intake air pressure sensorgenerallylocates in apositionbetweenthethrottleand theintake manifold; Somesuperchargedmodelsdonotcontain intake air pressure sensor, in this condition ,connecttheturbopressure sensor(air flow meter) is OK.
ii. The installation process, take Volkswagen 1.4TSI as an example

Find theturbo pressuresensor

Findcomputer ligatureprinted " TURBO".
Pull off thesensor plug, insert wire harness into the corresponding socket

Find theintake pressure sensor

Findcomputer ligatureprinted " MAP".
Pull off thesensor plug, insert wire harness into the corresponding socket
Fixed the compute in the proper position,installation ended
