Ratings and reviews

I have used Torque Pro for years, but can never get it to read powertrain/stabiltrac warnings on my 2007 Suburban, so I tried Car Gauge Pro. It may work, I don't know. I couldn't get it to do anything nor could I find any instructions or troubleshooting. No real support of any kind.

Looks and behaves like it was built for a commodore 64. I was able to get it to do an injector buzz test on a 6.0 powerstroke...apart from that it's pretty useless

The app can find my device, I can see the led's blinking so they communicate, but it states connection faild . It doesn't work

What's new

* Bug fixes with Android 14 behavior
