Carista OBD2

although i'm happy with the app & carista evo, the long description incorrectly states in the pricing if using the evo & select yearly subscription, you'll receive a one month free trial. i was told by carista the trial was discontinued in oct 2024. the description needs updating . beware it was easy to make customization to my '23 Camry. for that, it proved inexpensive compared to other options and i was able to "test drive" different values over the course of several days without bothering a professional). unless one "turns a wrench" (not me), go for the short subscription .. they're cheaper ways to read & clear codes (turn off the check engine light). at least for the Camry, the app does nicely bring together settings that are available via several different interfaces with those that are hidden into an easy to use menu. there's indication of being able to perform some service routines for which the diy fixer may find value in the subscription model (again, not me).

First, it works perfectly. For customization, though, while there are probably a hundred different options I can customize, most are options I could already customize right from the car’s menus. They also include a lot of useless options that nobody would ever care or want to change. That said, I bought it to fix two issues and it was able to solve one beautifully. I used it to shut off the engine auto-off when stopped at a stoplight. For that alone, it was worth the price of the module (and I accomplished that with the free trial, so no cost for the app). The other issue I was hoping it would fix was the unreasonably loud and long warning dings when I open the car door with the car running. Sadly, turning that off (or even adjusting the volume) isn’t an option. Either way, it was worth the cost for the one problem it solved, so I can’t complain. It may be great for the diagnostic tools, but I have no need for that, so I can’t comment.

I love this app. I knew I wanted to change a few characteristics of how the lights operate, windows operate, and the locking procedure for the car. I was able to change much more than I anticipated through the app and the supporting Carista adapter. Recently this new update came out, claiming that you can change the volume for the stupid sound aktor device Vw/Audi uses, and while most features added to the app work with my car, this one doesn’t seem to even show up as an option to change. I’m even able to change the torque steer compensator; so while the app has tons of features, some may claim to be compatible with your car but not functional. I’ll do 5 stars if the devs can fix the issue or come out and specify which models of Vw/Audi get the sound aktor ability. EDIT: function doesn’t apply to my vehicle. 5 stars added.
