First off I understand the whole octane/power thing, so that is not what this question is about. And yes, Chris does an excellent job of explaining a lot of things. Thanks!

Out of curiosity though, are newer computers in cars able to "read" what octane is coming through the system and then advance timing if it is able to?

I ask because I remember an old episode of Horsepower TV where the two guys both were racing Mustangs. The older guy put octane booster in his tank at the track and stated that the car's computer would see the extra octane and advance the timing accordingly. Does this actually happen, or is it just TV BS?
