We observe a sudden drop of the Maximum Combustion Pressure (Pmax) of a single cylinder. Pmax became less than Compression Pressure. The engine is RTA-FLEX. What may be the cause of such drop?

This happens because Control Unit protects the engine from operation in abnormal condition, like when Pmax or exhaust gases temperature go abnormally high. Control Unit adjusts ignition and exhaust valve opening timing for the time it is observing abnormal operational parameters.
