Connection issues

Ever since I purchased the lifetime update this fails to connect after every new update. My WiFi connect works fine on other programs. Just fails on this one. Why does this keep happening?

Removed option to view all sensors

This app was good until they removed the option to view all sensors, still reads cel but without the option to view sensor readings can’t really do much else on the app. Free version btw.

Stopped working with update

This worked great until a recent update, now it doesn’t read or clear codes. It connects to the OBD but can’t read codes.

Bolt driver

Long term Torque Pro user. Understanding the manipulation of pid equations was helpful for customizing. It was nice to have some out of the box functionality as well as iOS/CarPlay compatibility. I would like to see the phone app dashboards in CarPlay rather than just text, but I believe that is a CarPlay graphics limitation? For EV use (my case), displaying cell voltages to 3 decimal places is a must. I hope to see that in future releases. Overall, an excellent product. Thnx.
