A- Driving relax on a very hot summer day.

B- Driving hard on a very hot summer day.

I mean, K20 engines have knock sensor: this is why the ecu will retard ignition if knock happen. Engine lost some "ponies" in this case. I personnaly think that knock happen more often under hard driving than gentle driving. Correct me if I'm wrong.
