Perfect Tuning Universal Gauge MS3Pro, MS3, MS2



This tiny, gauge sized display can show up to eight sensor readings at a time, in the space you’d need for a standard gauge! Plus, this gauge monitors almost all your ECU’s sensor readings, and can interrupt its display to switch to a warning message if you run into an unsafe condition such as overheating, leaning out, and more available warnings. Fits in a standard 52 mm gauge cutout, and measures 70 mm (2 3/4″) outer diameter.

The NEW Perfect Tuning 24x Multicolor OLED Universal Gauge is enclosed in billet aluminum and boasts a real carbon fiber face plate! On-board LUX sensor auto-adjusts for day/ night time viewing.

Out-of-the-box compatible with all of the the following:

  • MS3Pro Ultimate, EVO, 1st Gen & MS3Pro Plug & Play
  • MegaSquirt 3 (MS3)
  • MSPNP Gen 2 & MegaSquirt 2 Universal (MS2) 
  • Microsquirt (all versions)

The following data can be displayed from MSPNP Gen 2, MS2 Standalone 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

And for MS3 / MS3Pro, all the above PLUS

  • MAF (Mass air flow)
  • Gear
  • VSS (Vehicle speed)
  • 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 ECU can read it over CANBus, display it in TunerStudio and datalog the value (including battery voltage!)




Configure your gauge over a Wi-Fi connection with smartphone, tablet or laptop.

Module d'alarme

Flying lead type wiring harness and mounting hardware included.

Requires MS2/Extra 3.4.0 or later, or MS3 1.4.0 or later firmware, as this uses the Dash Broadcasting feature.

      Q When will the ethanol % be available? answer now
      Asked on February 23, 2018 9:09 am

      The gauge can currently use an ethanol % reading from an MS2 or MS3 ECU. Adding direct reading of a fuel composition sensor is something I don't have a full release date for - it will depend on how long it takes to fully debug the firmware upgrade.

      Yes. It will be made with the alarm module. You can configure up to 16 alarms. So you can setup a condition where the rpm is greater than 6000 rpm, for example. It's possible to define the color, fast blink, slow blink or steady on and many other parameters.
