I recently discovered the +Carista
app which, in addition to the standard diagnostics functions that work on any OBD-II car, allows for vehicle-specific customizations on a variety of Toyota/Lexus/Scion and VW/Audi vehicles manufactured after 2004 - including my Subaru BRZ which utilizes Toyota electronics.Depending on your particular vehicle, you can alter settings like:
• Blink/beep when locking/unlocking with remote
• Single/double/long press to open trunk lid with remote
• Unlock all doors or just the driver's door on first press with the remote
• Enable/disable Daytime Running Lights
• Adjust auto headlight activation threshold
• Adjust/disable "coming home" lights duration
• Automatically lock doors when moving
• And many, many more (depending on the car, of course)
Carista is also able to perform some vehicle-specific diagnostics on systems that the OBD-II protocol doesn't directly control, like navigation, ABS, airbag, etc (again, depending on the car).
The app and OBD diagnostics are free; the vehicle-specific diagnostics and customizations require a $10 in-app purchase - which is actually a steal compared to the dedicated diagnostic tool you'd normally need for these functions (easily $900+) or even a trip to the dealership. Fortunately, the app will let you see what customizations are available for your vehicle before you hit the pay-wall.
You can check if your vehicle is supported at www.caristaapp.com/supported-vehicles/
, and download the app from https://play.google.com/store/apps/details?id=com.prizmos.carista
. You may also want to join the Carista beta-testing group to make sure you have access to the most/latest features: https://groups.google.com/forum/#!forum/carista-testing. And, naturally, you'll need a Bluetooth OBD adapter to connect to your vehicle; you can find one on Amazon for as low as $10 which should work fine for diagnostics (http://www.amazon.com/gp/search?ie=UTF8&camp=1789&creative=9325&index=aps&keywords=bluetooth%20OBD&linkCode=ur2&tag=daslab-20), but if you want to use Torque or another app for real-time display and logging features you'll probably want the faster OBDLink LX (http://www.amazon.com/gp/product/B00H9S71LW/ref=as_li_qf_sp_asin_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B00H9S71LW&linkCode=as2&tag=daslab-20 ).
