Yes:

Changan Pakistan has rolled out at least two ECU flash updates since 2022:

Improved air-fuel ratio management.

Optimized idle stability.

Enhanced spark timing control.

Some dealerships perform these updates proactively during service others only if an owner complains.

No official recall, but many 2021–2022 models have benefited from these updates.
