OneGauge OBDII & CAN-BUS Kit
This product is designed for OBDII enabled vehicles (those made in 1996 or later in the U.S.) and reduces the number of sensors you have to install. It can also communicate with CAN-BUS enabled engine computers available from many aftermarket manufacturers. Different vehicles and ECUs offer different sensor options, so please reach out if there are any critical sensors you want monitored. For vehicles without OBDII capabilities, you will need to purchase the OneGauge Hub, available here.
This kit includes:
- OneGauge Hub with power wiring and basic ABS box
- 7″ Touchscreen LCD
- OBD-II connector (wired or wireless) or CAN-BUS wires
For details on all components, please see our OneGauge Instruction Manual.
- Wired/Direct OBD-II Input: wired connection directly to your OBDII ECU. Supported only by ISO15765-4 (CAN-BUS) vehicles (see note below). Includes soldered module and 5-foot OBD-II cable. Extremely fast connection to read all of your engine computer’s data.
- Wireless OBD-II Input: wireless connection to your OBDII ECU. Supported by all OBD-II enabled vehicles (see note below). Slower connection, not recommended for speedometer and tachometer readings.
- CAN-BUS Input/Output: communicate with your aftermarket or standalone ECU. Please see note below to confirm compatibility. Additional programming fees may be required that are not included with this purchase.
OneGauge also supports aftermarket ECUs with CAN-BUS output options. The ECU must either allow user-configurable CAN-BUS setup or a readily available/published CAN-BUS protocol so that the OneGauge system can communicate with it. Please reach out to us before purchase to confirm compatibility!
A few critical notes on OBDII & CAN-BUS setups:
- Most vehicles do not monitor Oil Pressure as part of the OBD system. Please add an oil pressure sensor if that’s a gauge you would like to have.
- OBD-II compatibility: Vehicles made in the United States starting in 1996 have OBD-II ports. Wired/Direct OBD-II connections require ISO15765-4 (CAN-BUS) in your vehicle. All vehicles manufactured in the United States from 2008 on have this capability, but this website has a list of pre-2008 vehicles with CAN-BUS (http://www.auterraweb.com/aboutcan.html). For all pre-2008 vehicles, it’s is the customer’s responsibility to confirm compatibility- to check older vehicles, use this website. https://obdstation.com/obd2-protocols/
- Wireless OBDII systems send data readings 2-5x per second, and while this is relatively fast, it may make the Speedometer and Tachometer readings seem lagged or slow. To avoid this, we recommend upgrading to either the GPS Speedometer option or external Tachometer (or, for best results, both) so that readings can come in more quickly. Wired OBD-II connections read at 10-20x/second so these additional connections may not be necessary.
- Every vehicle reads different sensors, so some sensors may be available on some vehicles but not others. You can test this before ordering your OneGauge setup by purchasing an inexpensive OBDII bluetooth reader and determining which sensors are being read using your smartphone. OneGauge offers one free minor reprogram/redesign after the product is delivered to remove any non-working sensors and add any OBDII sensors that may be required.
- CAN BUS input: standalone or aftermarket engine computers with CAN BUS output are supported by OneGauge if they offer 1 of the following two options:
- Customizeable CAN-BUS configuration that allows you to define the parameters and protocol of your ECU’s CAN BUS output
- Available CAN-BUS protocol from the manufacturer so OneGauge can be programmed to communicate with your ECU (additional programming fees required).
