Buying Fuse

  1. What cars does Fuse work with?

    Every US vehicle sold after January 1996 has an OBD II data port near the driver's seat that Fuse can plug into. Not all cars support all data. The GPS and cellular connection always work, however and most of Fuse's functionality depends on those.

  2. Are there plans to make the Fuse available outside of the US?

    We'll soon be offering Fuse to international customers too. Sign up here to be notified when Fuse is available internationally.

  3. How hard is the installation and configuration?

    Fuse simply plugs into the easily accessible OBD II port that is already on your 1996 or later vehicle. There is a simple configuration accessed from a unique QR code or URL on the device that will allow your to set up your account. No tools are required and set up is simple and easy.

  4. Do I need a data plan?

    No, the Fuse data plan is included with the price of the device for 24 months. There is not data plan or monthly fee to use Fuse.

  5. What happens after 24 months?

    Its hard to tell what will happen with cellular data pricing that far out, but we anticipate it will continue to fall. The data may continue to be free after 24 months, but we can't guarantee it. Any charge would be small and easily affordable.

  6. Why does the device have its own cellular modem? Why not just use my smartphone?

    Fuse leverages a sensor plugged into your car, the cloud and a new mobile app to combine your life. The sensor connects using cellular technology to the cloud, constantly sharing the data into your private account. Using a sensor with built-in cellular technology enables you to get a constant stream of data from your car, even when you or your smartphone are not in the car. Fuse doesn't require any pairing with a phone and works with multiple drivers. For example, Fuse works when your teen, with a plain old cell phone, is driving the car. Or when your car is parked. See this update for more information.

  7. Where is my OBD II Port?

    The port must be within 3 feet of the driver and accessible without using any tools. Check in your car under the dashboard or under the steering wheel. This article on CarMD can tell you for any given make and model where the port is located.

  8. Will I be able to use my existing OBD II device with your software?

    You can use any CalAmp LMU-3000 (GSM), CapAmp LMU-3030 (GSM), or Xirgo XT-2000 (GSM) with the Fuse network and mobile app. To do so, your device will need to be reflashed to load a new script. Your device will also need a new SIM card to put it onto the network we use for device connectivity. Note: your device can only work with one network at a time, so making your device compatible with Fuse will mean that it no longer works with the system it is currently on.

  9. Do you have a privacy policy?

    Yes, our privacy policy is online.

  10. Will there be an API?

    Yes, there is an API. The Fuse Management Console is an open source project and can be view on Github that shows how to use HTML5/CSS/JavaScript to interface to the existing API. The backend code that creates the API is also open source and available on Github. We're happy to help and answer questions if you're interested in working with the API.

Using Fuse

  1. Why is my vehicle showing a red stop sign?

    The red stop sign is an indication that Fuse hasn't received any data from your vehicle yet. Make sure you have linked you Fuse account with Carvoyant and then edit and resave the vehicle (just click on the vehicle name and then click "Save"). Finally turn the car on and off.

  2. When I click on "Authorize with Kynetx" in the Fuse Management Console, nothing happens.

    On an iOS device, you must disable "Private Browsing" for the app to work. You must also allow third party cookies.

    You can move the device from one vehicle to another, but you cannot have the same device associated with two vehicles in the Fuse system at the same time. So, you can either create two vehicles in Fuse and manually update them to reflect which vehicle the device is currently in or you can have one vehicle which is a mix of data from both vehicles.

  4. I bought a new vehicle, what should I do to put it in Fuse?

    Ideally, when you get a new vehicle, you should create a new vehicle in Fuse. This ensures that the right vehicle type is associated with your vehicle data. You can leave the old one (so you have it’s records) or delete it as you see fit. Be sure to remove the device ID from the profile for the old vehicle and put it in the profile for the new vehicle. You can't have the same device ID in two vehicle profiles at the same time.

  5. Why does my hybrid (or electric) vehicle report multiple trips for each trip I take in the car?

    The devices currently track trips based on engine state, IGNITION_OFF or IGNITION_OFF. This does not properly account for hybrids, electrics, and vehicles where the gasoline engine is not actually running at all times. We are working with Carvoyant to improve this feature so that these vehicle report trips more accurately. This is a high priority.

  6. Why isn't my favorite gas station listed in the suggested gas stations when I fill up?

    Fuse uses the Google Places API to get a list of nearby gas stations when the driver records a fuel purchase. Sometimes businesses are not in Google Places or are miscategorized. This blog post explains how you can suggest edits to your favorite gas station so that it's correctly categorized and shows up in Fuse.

  7. How are trip costs calculated?

    If you have made at least two fuel purchases and recorded them, then the last cost per gallon and computed MPG are used to determine trip costs. If not, we use data from manufacturer to determine the MPG of your vehicle and the Dept. of Transportation to determine average gas price in the US for the past week.

  8. The MPG in my vehicle doesn't seem right even though I've recorded fuel purchases.

    MPG is based on the miles you drive between fuel purchases and the number of gallons you purchase. Several things could affect the inaccuracy of the calculation such as not recording consecutive fuel purchases (make the miles drive higher than the really are and this inflate the calculated MPG) or not completely filling the tank when you fill up (making the number of gallons seem lower and thus inflate the calculated MPG).

  9. My fuel level isn't showing or is off

    Some manufacturers do not report fuel level to devices plugged into the OBD II port. Sometimes this shows up as no value. In this case Fuse simply doesn't show anything about Fuel level. Some vehicles show a value that is wrong, although usually the same wrong value regardless of the actual fuel level. In this case Fuse will show the bad fuel level.

  10. Why don't I see data from Fuse during a trip?

    Even though Fuse is recording data about a trip once per minute while the vehicle is on, it only reports vehicle status in the app at the start and end of a trip.

  11. Why did my GPS report the wrong location?

    Possible issues:

    • the number and/or position of the GPS Satellites may have been in a state that made it difficult to calculate the coordinates correctly
    • the device may have been downloading ephemeris data (the set of parameters that can be used to accurately calculate the location of a GPS satellite at a particular point in time) during that time period and had an issue with the receiver while it was downloading
    • the GPS may have experienced atmospheric effects which could cause it to be off
    • the GPS may have experienced multipath issues (where signals reflect off of things and cause all sorts of weird issues). Things like tunnels, buildings and hills can make GPS data unreliable at times
    • there may have been an issue with one of the satellites, but I didn't see any posted outages with GPS satellites during that time.

    Any of these things can give incorrect GPS coordinates.

  12. Why is the address that Fuse reports for my vehicle is sometimes off a little?

    The address that is reported is determined using the specific location coordinates (latitude and longitude) for the vehicle. GPS is accurate to about 25 ft with a 95% confidence interval. That means that 5% of the time it may be more inaccurate than that. On top of that the address API is using that location to try to determine the address. While the address is generally pretty good, it can be off. For example, if your vehicle is parked on a driveway between your house and your neighbors you might sometimes get your address and sometimes see your neighbor's.

  13. My car's "service" light came on, but I didn't see an alert from Fuse. Why?

    An indicator light on the dashboard may mean multiple things, and there may be multiple indicator lights. There are a ton of reasons that manufacturers may turn on an indicator light beyond just the diagnostic codes the Fuse sees. Unfortunately, none of those will be available through the devices that we use. Please confirm what the light on the dashboard means from the vehicle owner's manual. In more recent model years, the "Service Now" and "Check Engine" are usually separate, though even then, it's not guaranteed that just because the engine control unit turns on the indicator light a diagnostic code will be raised.
