What it does

Live values

Hundreds of ECU values, grouped into lists you build yourself and refreshed several times a second.

Fault memory

Stored faults with P-codes and plain-English descriptions, the history store and full freeze frames.

Logger and snapshots

Record up to 20 channels to CSV, replay them on a chart, and compare warm-idle snapshots over time.

Guided tests

Mixture audit, injector comparison, rough idle per cylinder and cylinder cut-off. Commands run only when the ECU's own conditions are met.
