OBD-II monitoring the Bolt

Three live readouts from my Bolt EV as seen in the EngineLink iOS app

Since I got the Bolt I’ve been looking for a way to view OBD-II data. For those who’ve not encountered it, OBD-II is a specification and connector; all vehicles since 1996 have it. (More at Wikipedia) The Bolt didn’t work with my copy of EngineLink, but… today it does!

The secret is this google docs spreadsheet.

It has the codes (secret decoder, literally) to let EngineLink understand what the numbers mean. So now I can create dashboards and monitors to my heart’s content.

You need hardware, mine is this one from Amazon, cost me $35:

More details on the spreadsheet, including how to do it on Android, links to other adapters and more. I love the internet sometimes!
