Connection reliability: Stable for most read/write operations. The driver maintains steady communication across OBD-II and manufacturer-specific protocols used by PSA vehicles.
Error handling: Reasonable: transient bus errors are retried, and the driver surfaces diagnostic-layer errors to the host software. However, in complex operations like module programming or ECU reflashing, intermittent USB glitches can cause session aborts if the host software does not implement robust retries.
Latency: Low enough for live data streams and parameter logging. Users performing high-frequency sensor logging will find the throughput satisfactory for typical workshop tasks.
