Carista OBD2 + Tundra 2022

You should wear your seatbelt.

I should wear my seatbelt.

No argument there, but my new Tundra has the most annoying seatbelt alarm I’ve ever experienced. It’s loud and it literally never stops. There are, sometimes, legit reasons to silence an alarm like that, like putting groceries on the passenger seat.

I think I should be able to alter anything I own. It’s my damn truck.

I rolled the dice on ordering a Carista OBD2.

It was just $29.99 for a little physical device that plugins into a port under the dashboard of the truck and allowed me to change otherwise inaccessible settings, like the seatbelt alarm.

To my surprise and delight, it was super easy to use and worked.

I plugged it in, downloaded the iOS app, and it connected right away. To actually change a setting I needed a subscription. They say they have a free trial but I didn’t see that option and had to pay another $9.99 for a month. Happy to pay it, as the other options I looked at were way more expensive.

Turning off the alarms was as easy as toggling a switch and pressing the save button.

One more that was very satisfying to change? Turning off the fake “V8” engine sound they pipe into the truck, which is apparently a way to mitigate the feeling that the “downgrade” from V8 to V6 makes the truck have less balls or whatever.

All of these settings are otherwise impossible to change via the menus and such available in the trucks interfaces themselves.
