Some vehicles built for sale outside of the US market may have different support, and might not be supported until later years.

Older vehicles than these listed typically use a variety of different OBD protocols (J1850 VPW / PWM, ISO-9141, ISO-14230 / KWP “K-Line”), which are not supported by this device. CAN is where we best innovate and add unique value to the market, so that’s where we focus.

100% Electric Vehicles are generally not expected to work properly with this product, as they typically do not implement the actual OBD-II protocol, even if they have an OBD port wired to them. Hybrid gasoline/electric vehicles conforming to the OBD-II standard are expected to work.

Protect Your Security!

DauntlessOBD is designed with wireless security in mind. LE wireless pairing with your mobile device requires a physical button press, so that only devices you’ve authorized can use it to connect to your vehicle. Beware of other OBD devices that are openly available with no wireless security, or a common password, that let just anybody nearby connect to your vehicle and send it commands at any time.


Just Say NO to Devices that Kill Your Battery!

Many OBD devices on the market can drain and possibly damage your vehicle’s battery if you leave them installed over time. We designed DauntlessOBD with efficiency and intelligent logic, specifically so that you can leave it plugged in on most vehicles. Rather than just making vague marketing promises, we’re happy to share our performance numbers:

  • Sleep Mode Threshold: 10 minutes of inactivity
  • Low-Battery Shutdown: approx <11.8 V for 1-2 minutes
  • Typical Power Consumption @ 12.5 V:
    • Sleep / Shutdown: <2 mA
    • Fully-Awake Idle: <36 mA

Sleep mode is intended to drastically reduce the drain on your vehicle’s battery when the ignition power is off. It will not be entered within 2 minutes of device power-up / reset, or within the threshold time after an active connection to the mobile app, engine RPM is detected, CAN data traffic is detected, or the device’s button is pressed. After entering Sleep Mode, this device will periodically enter a low-power wake-up to check for ignition / engine or data activity, causing a very brief increase in current draw, and then return to Sleep Mode. Mobile app connectivity is not possible until the device is fully awakened, which can be easily accomplished by pressing the device’s button or starting the vehicle’s engine. Depending on the vehicle, certain other activity may also wake it. These characteristics and thresholds are subject to change with future firmware updates.


The OBD Interface that Developers and Tinkerers Want

In addition to offering great ELM327-compatibility so that many existing apps work automatically for a wide variety of users, DauntlessOBD also offers additional commands to greatly ease the work of OBD app developers and serial terminal users, along with automatic switching to the GVRET protocol when you want to sniff CAN traffic with open source tools like SavvyCAN (via USB).

No NDAs, no closed ecosystem, no nonsense! We’re happy to publish a command set that you can use in your apps or from a serial terminal.

We’ve been in your shoes and have created the OBD device that modern app developers want, with the performance and reliability that users want. DauntlessOBD was conceived and designed by a professional developer with a life-long obsession with cars, and over a decade of experience in OBD-enabled mobile apps and other products. We understand and care about the Developer Experience, so that you can deliver a great User Experience.
