OBD Dump

OBD Dump

Reads every standard OBD-II value from your Bluetooth LE adapter, logs fuel trims and O2 sensors at idle and 2500 RPM, and packs it all into one report for Claude. Read only: it never clears codes.

01The car

02Connect

Plug the adapter in. Start the engine and let it warm up fully (about 10 minutes). Close any other OBD app first, because only one app can use the adapter.

Not connected

03Full scan

Starts by itself once connected. Takes about one to two minutes.

04Live logging

Keep this app open and the screen on while it logs. You can repeat any phase; the new run replaces the old one.
