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

[Mueller]

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)

Who ever markets this had better have some SERIOUS manufacturers insurance because they will more than likely be getting their asses sued!

I did this on my dyno in 2002 and 2003 when I was doing my cooling system test work and needed a universal throttle that was fast to install and remove and while it worked well I could certainly see that there are glitches that could promote a failure that could stick the throttle at wide ass open.... Fail safes could be used, as always but even those "Fail".....

The person that does this in todays modern world of lawsuites and trigger happy attorneys is asking to get their ass handed to them.

Sorry guys, thats thr truth from the retail side of the world, and it sucks.

Vehicle manufacturers may do this as standard equipment, but they can absorb the costs related to failures without losing their homes and businesses because of one prick that can't install something correctly.....
