Is the ECU Engine Control Unit in Changan Karvaan well-calibrated to handle variable altitudes and fuel types across different regions of Pakistan?

Areas like Murree, Swat, o r Quetta have different air density. Is poor ECU mapping o r lack of adaptive systems affecting emissions?

Yes, in some cases:

Karvaan’s basic ECU may lack adaptive altitude compensation.

In high-altitude areas like Murree, Quetta, o r Gilgit, air density s, affecting combustion if ECU doesn’t adjust.

ECU tuning may also not account for variable fuel quality, leading to detonation o r power loss.

⛔ Conclusion: The ECU lacks sufficient adaptability for diverse conditions in Pakistan, affecting emissions and efficiency.
