Are Changan Kalam’s engine tuning and ECU settings optimized for fuel efficiency in Pakistan’s climate and terrain?

Some mechanics suggest that better mileage could be achieved with different tuning. Is the stock calibration not ideal for local conditions?

Not entirely.
The ECU maps are generally tuned for:

Emissions control

Fuel-saving under ideal conditions

However, Pakistani roads, heat, and loads demand tuning for low-end torque and fuel richness. Some local mechanics report that ECU remapping with caution o r adjusting idle and air-fuel ratios results in improved efficiency and throttle response.
