OBD Fusion supports all OBD2 and EOBD vehicles sold worldwide. If you're not sure whether your vehicle is OBD2 or EOBD compliant, see this page for more information: https://www.obdsoftware.net/knowledgebase/obd2compliant. OBD Fusion can also connect to some JOBD vehicles that don’t support standard OBD2 protocols.
Electric vehicles (EVs) are not required to have OBD2 diagnostics since they are emissions exempt. If you are interested in using OBD Fusion on an EV, contact us first to inquire about support.

8 of 25Works plug-and-play with my Bluetooth adapter for 3.0L Duramax. Custom PIDs pull slip RPM, EGT, trans temp, boost, oil pressure, plus emissions stuff like DEF level, DPF soot load, regen status—essential for towing. Community PID files and forums make setup easy.
Use it each time I drive my LS swapped C10
I used this app to create a drive analysis script that runs through shortcuts, I currently have to auth through Dropbox and download files before I can use them in the script locally If there was a shortcut action to export the csv of the last data logs that would be amazing. Regardless this is an amazing app for what it does.
The app haves a lot of configuration tools and great dashboards, however it is not worth the purchase as the Apple CarPlay integration is terrible. You cannot monitor the information setup in dashboards with Apple CarPlay and that makes this a 2 star purchase. If the app had dashboard display for CarPlay, it would be well worth the $10 purchase price.
They don’t tell you what extended PIDs are supported until after you pay $15 for the license. I paid to get information to diagnose my AC issues on a 2019 3, and none of the relevant PIDs are even available through this app. No option for a refund.
Love this app
So I downloaded this, it’s a little bit clunky getting it to work with iOS. And then I find out that Nissans are not included in the program. You can upgrade of course for another $75 if you want a template/macro that is only updated up to 2021. So I don’t recommend it.
They advertise wrongly that the “OBD Fusion” paid app “contains the same functionality” as this free OBDLink app. Far from it. Explain that there are significant differences where both apps may be required. You got my money for your MX+ hardware over this misleading point. But no high rating.
