OK, I know this is kind of theoretical and hypothetical and everything, but...how smart is the computer chip in our '05 Stangers? For instance, if the car was at sea level and then drove to a higher elevation, would the chip be able to sense/read less O2 and mix less fuel accordingly? Or maybe closer to home...can the chip somehow read or know when a new exhaust system (like, uh, the JBA Evol on a V6) is installed? Is it collecting data as we drive, and then processing it and even making adjustments accordingly? I'm a newbie geek on this car tech stuff...thanks in advance for any info.
