To those that own vehicles with throttle by wire, do you like or hate it? I've owned 2, a 2002 isuzu rodeo 3.2 and currently a 2005 trailblazer 4.2L. Ironically, both trucks share the same GM/delphi TBW. On the rodeo it wasn't too bad in that the throttle coresponded pretty much exactly with the go pedal. It's different on the trailblazer being very much software controlled. For instance, flooring the gas pedal wont give you WOT until higher RPM ranges. FWIU, this is GM's 'torque management' system. Some of the management revolves around safety, such that the engine wont rev past ~3K while in park. You never really have 100% control over the throttle with such a vehicle. It's nice in that it protects the drivetrain, but I dont see any benefit other than that.
I don't like it!
