The Perfect Tuning Universal Gauge is a new product. The gauge is compatible with all the Megasquirt ECU except the Megasquirt 1:

  • MegaSquirt 2 (ms2) and MSPNP
  • Microsquirt (all versions)
  • MegaSquirt 3 (ms3)
  • MS3Pro including all MSPNP-Pro
  • MS3Pro Ultimate

Here is a list of the available data to display on the gauge coming from the MS2 and Microsquirt:

  • MAP (Manifold Air Pressure)
  • RPM
  • CLT (Coolant temperature)
  • TPS
  • IAT or MAT (Intake Air temperature)
  • Ignition timing
  • AFR1 and 2
  • AFR Target
  • EGO Correction
  • EGT1
  • Battery voltage
  • Generic Sensor 1 and 2
  • Knock Retard
  • VSS (Vehicle speed)

And for the MS3 and MS3Pro, all the above including

  • MAF (Mass air flow)
  • Gear
  • Injector timing
  • Cam IN and EX positions
  • ECU error code
  • Fuel Pressure
  • Oil temperature
  • Oil pressure
  • Speed sensors of each wheel
  • Knock on cylinder 1-8
  • And more!

The gauge can also be connected to up to 3 sensors with the 3x 0-5v analog inputs and can be used as an expansion board. This means that if there is a sensor connected to the gauge, the megasquirt can read it over CANBus and display it in TunerStudio and datalog the value.

The gauge also display battery voltage.

The billet anodized aluminum enclosure and the real carbon face plate give an incredible look.

The colour OLED display allows to display more information than a standard gauge and the colours are configurable. Actually there are 9 different screens and others will come. Contact us if you have specific needs or ideas!

24x multicolour LED gives a quick way to see what's happening.

One of the biggest features is the alarm module which is very powerful and flexible. It allows to monitor each input and notify when there is something abnormal. The configuration of the alarms are made over the web page with a Wi-Fi connection with a smartphone, tablet or laptop.

Here is few alarms configuration examples:

  • Abnormal temperature (oil, coolant, EGT and more).
  • Abnormal pressure (oil, boost, radiator and more).
  • Air fuel mixture too lean or rich based on specified conditions.

There are two buttons on the gauge to change the displayed screen and change basic settings. The advanced configuration is done over a webpage with a Wi-Fi connection to the gauge with any smartphone, tablet or laptop.

The screen brightness and LEDs adjust itself automatically with the luminosity sensor.
