I am sorry to say but its not "Only" computers. So a year or two ago my son asked "how do you tune a car to go faster".
My answer was, in the past you might have :-
1. Polished the manifolds to allow faster air flow. 2. Fitted bigger valves to improve air flow. 3. Fitted a better carburettor to get more fuel into the engine. 4. Changed to a "sports cam" for improved air and fuel. 5. Fitted a sports exhaust. 6. If really serious bore it out or fit a crank shaft with a longer stroke to increase cubic capacity 7. Fit High Compression Pistons....
Of course these days you just change the chip in the Engine Management Unit....
Yes. But the (possibly) interesting thing is, you could STILL do things 1 through 7 in your list above, and make the car go faster. As long as the engine control computer didn't "compensate" for what you'd done, of course. There's still a low-tech gas-burning engine under there somewhere. The same holds for computers. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
