P3 Cars Analogue Turbo Pressure Monitor for Audi 8V A3 S3 RS3 2013 onwards

Looking for a tidy, factory-style way to keep an eye on manifold pressure, vacuum and electrical system health on your Audi 8V? This P3 Cars analogue display delivers rapid, precise readings with discreet integration and the flexibility of two auxiliary 0 to 5 volt inputs. We run this unit on our own cars and our customers love the accuracy, the simplicity and the OEM-like look in the cabin.

Core functions

• Turbo pressure and manifold vacuum via dedicated analogue transducer plug (yellow / purple / black). A boost reference from the intake is required. Boost tap not included.
• System voltage from red / black power and ground for quick health checks of your charging system.
• Aux input 1 (brown) accepts any linear 0 to 5 V signal such as oil pressure senders, fuel rail pressure and coolant temperature sensors.
• Aux input 2 (blue) accepts any linear 0 to 5 V signal such as intake air temperature probes and compatible wideband controller outputs.
• Optional dimming (green) can be tied into the lighting circuit then enabled in the menu for night-time comfort.

Why it belongs in your 8V

• Fast, steady readings that help protect tuned engines on the road, dyno and track.
• Two spare channels to visualise vital data from common 0 to 5 V sensors without clutter.
