Advanced Gauges

Accelerometer (G-Force and Roll/Tilt)

  • An accelerometer (soldered to the Hub by OneGauge) can be used to provide vehicle roll and tilt readings for off-road use or g-force readings for racing and other applications. No installation necessary, but calibration may be required, which can be accomplished on the setup menu of our standard LCD touchscreens.


Air/Fuel Ratio (AFR or Lambda)

  • OneGauge can support any air/fuel ratio sensor and controller that provides a 0-5v analog output. We recommend Spartan brand controllers (with a Bosch sensor) but we support a number of others including AEM, Innovate, Wideband WB-1, Daytona, Ballenger, LD Performance, and more.

Ports B6 and B7 provide AFR and AFR2 readings, respectively. These are programmed to work with the output of a Spartan Oxygen Sensor by default, but we support any AFR controller with a 0-5v analog output.

Installation – Please read!

  • Oxygen sensors install into a bung that must be welded onto your exhaust in an appropriate location, which depends on your vehicle and exhaust configuration. Please consult an exhaust specialist if you need this work done and are not confident doing it yourself.
  • The OneGauge oxygen sensor setup accepts analog (0-5 volts) from a variety of oxygen sensor controllers. It is necessary that the controller be powered independent of your OneGauge setup. The controller needs to be powered anytime the vehicle is running to regulate the oxygen sensor, while the OneGauge setup can be switched on off. To ensure that damage does not occur to your oxygen sensor, please ensure that the unit is always powered when the vehicle is running.
  • When your AFR/Oxygen sensor arrives it will likely only have a ground and signal connection. It is the user’s responsibility to provide power to the controller through the supplied wiring and ensure that the controller is ALWAYS on when the vehicle is running. Because the OneGauge maybe triggered on and off during running we recommend a separate, ‘always on’ connection. Please see provided instructions for the Oxygen Sensor/Controller that was included in your kit to reference wiring colors and recommendations from the manufacturer.


Exhaust Gas, Cylinder Head, and other High-Temperature Sensors

  • Inputs for EGTs and other high-temperature measurements can be added to the OneGauge Hub for use with K-type thermocouples.
  • OneGauge requires ungrounded, electrically isolated K-type thermocouples. The thermocouple wires must not have electrical continuity to the sensor’s metal body, sheath, mounting threads, ring terminal, engine, or exhaust. Grounded-junction thermocouples are not supported because they can create ground loops or expose the EGT module to damaging vehicle electrical voltage.
  • Compatible thermocouples are available in many sizes and styles, including threaded EGT probes, enclosed-tip probes, exposed-tip probes, and ring-terminal sensors used for cylinder-head temperature. Customers may purchase their own sensors, but they are responsible for confirming that each sensor has an ungrounded or isolated junction. We recommend using OneGauge-approved thermocouples whenever possible.
  • There is still a charge to add the EGT modules required to connect thermocouples to the OneGauge Hub.
  • K-type thermocouples are commonly used on diesel engines for exhaust-gas temperature and can also be used for cylinder-head temperature and other high-temperature measurements. The usable temperature range depends on the specific probe construction and manufacturer rating; many EGT probes are rated for temperatures approaching 2,000°F.
  • Standard (V3) OneGauge Hubs can have two EGT modules added to accept two sensors. For additional sensors, OneGauge has various expansion modules available.
  • OneGauge can support up to ten k-type thermocouples (EGTs and/or CHTs) at a time with no custom work. More is possible, this just requires a little custom labor.


Ethanol Content

  • OneGauge can use a standard Flex-Fuel sensor, but we can often program in different sensors. Please reach out for more information.

 

Tire Pressure/Temperature Monitoring

  • OneGauge uses a CAN bus tire pressure/temperature monitoring system. Up to 10 tires can be monitored on a single unit, though for special applications additional units can be added as well. We recommend the screw-on style sensors as the batteries can be replaced when needed, but valve-stem style sensors are available.
  • OneGauge also offers infrared tire and track temperature sensors per request.
  • Please note that these are considered "racing" sensors. They are expected to last an industry standard of around 3 years, but daily driving usage can shorten this lifespan. Because they are racing sensors, they transmit wireless data anywhere from 10 to 100s of times more frequently than an OEM sensor, meaning while OEM sensors can last 5+ years, racing TPMS sensor battery life can be roughly 3 years.
  • While these sensors often last round 3 years, we do not warranty them beyond 90 days after the package has been received. This is because of the abuse that TPMS hardware often take in aftermarket vehicles.

 

Transmission/Gear Position

Manual Transmissions:

All OneGauge products can calculate current gear based on RPM, Speed, and transmission/rear end ratios. These ratios can be programmed into the OneGauge using a standard LCD screen, but if another screen type is being used please reach out to OneGauge to have them programmed through an update.

Automatic Transmissions:

  • OneGauge currently uses the hardware from a Dakota Digital GSS3000 unit that installs a small device on the transmission to read the position of the shifter lever in order to display a “PRNDL” reading on the dash. This is an option upgrade for those with automatic transmissions.
  • To physically install the hardware, please refer to the instructions provided by Dakota Digital.
  • The following steps are taken to calibrate the setup if you’re using an LCD Screen:
    • Navigate to the Transmission setup screen (Touch top left corner of any gauge screen, then ‘setup’ menu) and select Trans Position Setup. Touch ‘Turn On’ to enable this feature.
    • After the Dakota hardware has been installed (picture below) and the three wires are connected, the unit will provide a voltage reading that is displayed above “Auto Trans On”. The reading at the top left of the screen shows the current gear.
    • As you shift the lever through the various position you should see this voltage number change.
    • For each gear, put the transmission in that gear and allow the voltage reading to settle, then click ‘set’. Move the lever through each gear, pushing ‘set’ for each. For any gear that is not present on your transmission, leave it at ‘0’.
    • When you’re done, ensure that the gear reading is correct for each gear. If you have any trouble, please reach out to us at info@theonegauge.com!

Customers using an Android tablet or PiDash setup will need to measure the voltage on the input terminal (green wire) of their GSS3000 module to determine the voltage for each gear so it can be programmed manually.
