Redesigning the Porsche 964 & 993 HVAC/Climate Control System

Our latest Youtube video explores a current Classic Retrofit R&D project to re-engineer the cabin air circulation and ventilation systems on Porsche 964 and 993 models. This project was a logical progression from an earlier 18-month project to redesign the troublesome Porsche 964 CCU - the dash-mounted control unit - to a fully microprocessor-controlled ECU and deliver a modern solution to a well known problem.

Watch the video below for a sneak peek at the separate project to develop an electric heating system for this 400-volt EV customer. There is some crossover between the two systems (ICE and EV), but the 12v designs are still in the test phase. Due to the controller requirements, the electric heating system will be an addition to our A/C system and not a standalone project.
