Which risk increases for a turbocharged gasoline engine operating at high altitude with fixed ECU mapping?

💡 Explanation

At high altitude, with less total air, a fixed ECU map injects excessive fuel because the air-fuel ratio is too rich. Therefore knock due to high pressure results, rather than lean mixtures, oil issues,or turbo lag as those relate to separate sensor failures.
