Crossed my mind today, is the RS250 drive by wire with an electronic throttle?

I know theres a few motors on the market with this now, BMWs and the like and I was out for a run changing the throttle with the RS Monitor and I wondered how this was possible if its a standard mechanical throttle set up.

Could anyone with some technical knowledge feed my curiosity :sweatdrop:

Its the ECU that remaps the car to the various modes, similar to the cruise / speed limiter, you set it, it keeps to it. ECU determine this and not the throttle linkage.

Most modern cars are drive by wire already. This is necessary to enable traction control systems.

no, it is not. although it is easier to apply TC with electronic throttle control (I assume this what you meant). but think back to the 80s. mercedes introduced TC in their cars which then run on mechanical driven fuel injection (K jetronic by bosch) and throttle control by linkage.

And you usually spark cut instead, which is rather on the violent side. Torque smoothing it much more pretty. Can be done with a cable throttle but much better with dbw.

Spark cutting isn't good for your cat either. Sounds good though... ;)

I think most racing cars that have TC use that method.
