octane/HP rumors?

That ability has been around for a while, and is done via the knock sensor, but very few ECM's actually take it to it's extreme. basically, the ECM has programed curves in it, and it will advance or retard the timing depending on which of it's many preprogramed curves the sensor signals are telling it to follow. If it senses a signal from the knock sensor before reaching the preprogramed max ignition advance, it will not continue to advance, and theoretically that could mean never reaching your potential. But, this is very unlikely, unless you have already advanced the timing, and are deceiving the ECM.

There are no cars in production, that I am aware of, that will just keep advancing the timing until it knocks. They all have preprogramed limits.

Take care,
