Drive-by-wire for dual carbs/throttle bodies???, would you run them?? Options

A lot of newer cars do not have the traditional cable that goes from the gas pedal to the throttle body...instead the pedal has a potentiometer*, this in wired to the ECU which tells the throttle body how much to open, just because you have your foot buried to the floor, the throttle body might only be open 50% since the ECU is dictating what is going on.

Now a drive-by-wire throttle body could be wired directly to the pot. on the gas pedal to be 1:1 at all times......with a setup like this on dual carbs or individual throttle bodies, no need to worry about thermal expansion of motor and how that effects the linkage.


* (similar to a variable resitor which varies the voltage output depending on foot placement)

Having been involved in testing some of the most advanced control-by-wire systems on the planet, I would say that this should not be attempted by someone who does not have a firm understanding of control systems and FMET. Amazingly strange things can happen in suprisingly simple systems. (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) The liability is too great (not just life and limb, but even just an expensive engine). Note that I am not typically a nay-sayer to people's ideas.

for some reason I have a fear that the kid down the street with the remote controlled car could be having an ill effect on the throttle in my car (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif)
