Protomotive Engineering Logo Pressure Sensing!
84-89 Carrera:    Pressure Sensing is now available for 1984-1989 911 Carrera's, enabling high output racing engines, turbochargers, superchargers, multiple butterfly racing intakes, etc. to be applied to the already very competent 3.2L Carrera engine. By ridding yourself of the airflow meter, as well as a Mass Flow Sensor, this leaves you unrestricted in intake manifold design, and allows calibration on turbocharged engines to compensate for any boost condition. Complete packages available to convert existing DME's to Pressure sensing. Pressure Sensing packages include a copy of the Motronics Calibrator, but is limited to the pressure sensing applications unless purchased otherwise. Live tune can also be applied to these systems to create a laptop programmable system. 
 
Parts Only: $1,850.00
Installed and calibrated: $2,650.00
Installed and calibrated on engine dyno: $3,240.00
89-94 C2/C4:    We have also converted the 3.6 Motronics for the 1989-1994 Carrera 2's and 4's to throttle position sensing for racing applications where extremely high-overlap / high-lift cams, and single stack manifolding would make everything else non-functional.

Installed and calibrated on engine Dyno: $3,240.00
94-95 993:    Although the 993's have a very low restriction mass flow sensor, they can also benefit from pressure sensing.  Dyno tuning has shown up to 30hp gains, normally aspirated, by removing the mass flow sensor, air box and going with a low restriction air filter.  Turbocharging is where the major gains can be had.  The factory mass flow sensor runs out of range at 470-490hp, and that's just where the 993 engine starts to breath.  Pressure sensing allows any power level to be obtained within the 0-250kpa range of the sensor, ie up to 1.5bar boost, all with unsurpassed drivability and power at all levels.

Coming Soon!    944 Turbo's will soon be able to take advantage of Pressure Sensing Motronics.  Rid yourself of that flapper type air flow meter, or that aftermarket mass flow sensor and go where most racing-only 944's have been.  How much power did you say you wanted to make?!!!
