There is only one car thats electronicised enough out of the box to drive by plugging a computer in.
Cant remember the name off hand but its drive and steer by wire, i think the brakes are fairly conventional though. Its one of those supercompact city cars.
Theres only a few very late model cars that are throttle by wire. The ecu might well control 98% of everything but the foot pedal is still cabled to the butterfly valve in most cars. An EFI diesel might be easier to do, as i recall they don't have a butterfly valve.
Electric power steering is only just coming into main stream cars and hydraulic systems (as i recall) rely on a bar bending in the power steering assembly to do the power assist, so you have to turn the wheel to get the power steering to do anything.
Same sort of thing with power assisted brakes, The only thing that actually applies the brake without the person putting their foot on the pedal is traction control, electronic brake assist applies the brakes harder depending on how fast you press the pedal down.
ODB is really just for reporting and setting stuff about the engine, timings, injector durations, sensor readings etc. _________________ Mechanical engineers build weapons, civil engineers build targets
