Readouts and connections

• Manifold pressure via the dedicated analogue boost lead (yellow or purple or black). A boost reference source is required. Boost tap not included.
• Auxiliary Input 1 on the brown wire accepts any linear 0 to 5V sensor signal.
• Auxiliary Input 2 on the blue wire accepts any linear 0 to 5V sensor signal.
• Charging system voltage read through the red power and black ground wires.
• Optional auto-dim with the green wire connected to a lighting-on circuit, then enable in the configuration menu.

What you can display with 0 to 5V inputs

Configure the unit to show popular performance data from compatible sensors: oil pressure, fuel pressure, ethanol content analyser output, wideband lambda or AFR controller output, intake air temperature, MAP, coolant temperature, gearbox temperature and more. If the sender outputs a linear 0 to 5V signal, you can scale it for this display.

Vehicle compatibility

Audi C7 4G platform 2011 to 2018: A6, S6, RS6, A7, S7 and RS7. Perfect for 3.0 TFSI and 4.0 TFSI models looking for an OEM+ vent-mounted monitoring solution.

Installation guidance
