Common Questions

 

Which server version should I buy?

The Dual Bus OBDII version will serve most users. It includes a cable to connect to a standard OBDII port in most cars, and can be combined with a 3rd party OBD adapter cable to work with most Teslas. If you have a 2018-2021 Model 3 or Y and sure you need data from the extra chassis bus, you can add on an underseat extension adapter.
Dual Bus DB9 has a standard Vector CAN transceiver dSub connector for lab/commercial use or building your own harness.
A Rivian version includes a homemade adapter to plug into two (of the many) can busses, with limited data available, however you most provide 12v or USB power separately. It's not yet for everyone but does work with Teslax. Please contact first before ordering to review installation.

 

What cables do I need?

Many cars that have an OBDII port do not need any additional cables. Most Teslas will need an additional CAN to OBDII harness from a 3rd party.

Tesla Model 3 & Y center console harnesses are available at Amazon 2019 or 2018, GPS Tracking America, E-Mobility (Europe), and AliExpress. 2021+ can use this dual bus adapter from EVOffer with the new A-pillar connector.

Tesla Model S & X diagnostic connector harnesses from Maxwell are recommended for dual bus support. 2021+ should use this dual bus adapter from EVOffer. Single bus versions are commonly available elsewhere.

Rivian support may be coming soon with a custom adapter. 

Microdisplays require any microUSB cable for power, which will vary on your installation preference and your car's USB port type.

Something stopped working after a Tesla update!

Unlike most other car manufacturers, Tesla makes small change to their communications networks with each software update. If they change something with data your display or server is monitoring, then it will now have the wrong information. Usually we just need to make some changes to the Analysis signals. Contact me or keep an eye on this recent changes notice page.

Do you ship internationally?

Yes, Shopify handles this at checkout and even offers discounted shipping rates. Beware mail can take weeks, so I have UPS and DHL options as well. Note many countries may charge you VAT or customs fees after receipt.

Where are the manuals?

On GitHub! I recommend reading through before purchasing.

 Will this work with another brand car?

Probably! Most cars have CAN networks, but I would need help finding the connection (it's often in the OBD port) and decoding the data (sometimes DBCs are available online). If you are willing to help, get in touch!
