Audi S4, A4, S6 Boost Gauge With Optional "Programmable Peak Hold ^tm"

Custom In-Dash 20 Indicator LED Boost Gauge For Your Audi S4, A4, A6
This Gauge is Available in 20, 25 & 30 PSI Versions

In Dash 20 PSI Boost Gauge Kit With Optional Peak Hold Option (Using OEM Bosch MAP Sensor)

The kit includes everything you need in order to build your own accurate (+/-  0.250 PSI) fully functional turbo boost gauge. It takes the signal from your car's existing pressure sensor and monitors the boost pressure "Real Time".  Results are reported on 20 LED indicators with an accuracy of approximately +/- 0.250 of a PSI when installed and setup correctly. As you can see from the example photograph below, 1 indicator corresponds to exactly 1 PSI. 1 to 20 respectively.

The Programmable Peak Hold ^tm Option is available on request. It includes user selectable modes configured with an external switch, potentiometer and/or a fixes resistor. A single indicator remains on for a programmed amount of time indicating the Peak Boost Pressure reached. If a higher boost is recorded before it is reset it moves to the higher reading. Spikes can easily be monitored and boost peaks tracked efficiently.

Programmable Peak Hold Modes Available:

• Indefinite Delay/Decay (Peak hold remains on for a long time before slowly decaying)

• Pre-Set Delay/Decay (Peak hold remains on for a fixed time before decaying)

• Variable Delay/Decay (Peak hold is adjustable via an external potentiometer)

• Reset (Peak hold is reset to zero by an external switch)

• No Peak Hold (Peak hold feature is switched off by an external switch)

Indicator colors can be customized in any combination of Red, Green, Yellow, Amber & Blue.

In Dash 25 or 30 PSI Boost Gauge Kit (Utilizes an External Computer Grade Sensor)

Other customized boost readings are also available up to a maximum of 30 PSI, but they do require an external Sensor that we supply. A computer grade external pressure sensor is requires for 25 or 30 psi units and is optional on 20 psi units. Each indicator is calibrated to 1.250 PSI for the 25 PSI unit and 1.5 PSI for the 30 PSI Unit.

The unit also includes custom "Dimmer" technology that automatically dims the indicators for night time driving to an adjustable pre-set level,  when you turn on your car's master light switch. The night time brightness can be adjusted to suite individual requirements.

An accurate "Real Time" boost gauge is an absolute must, especially if you have done any non stock performance upgrades to your car. Such as; installing a new chipped ECU, increasing turbo boost settings, adding boost controllers etc.  Calibration is easy to do and default components are provided for sea level operation. The circuit is flexible enough to be configured for any altitude if needed. You can mount the Indicators anywhere you like. But we recommend putting them in the existing tachometer dial in your car's instrument cluster.  This is not too difficult to do and is discussed in detail in a dedicated article on this web site under Audi S4 Twin Turbo.  Yes, they can be fitted right into the car's dash board. The control unit is so small it can easily be concealed behind the dash.
