Is it to warn you? Even my toilet cistern can slow down smoothly.

On cars? Yes. Cutting the engine abruptly when you hit the red line
wouldn't be good so they simulate ignition breakup to give you a hint.

But at that point you've already gone over the peak of the power curve.
I'd just make it drop the curve more quickly so it can never go too
fast. The driver would still feel the lack of power.

Engines that run stochiometric have to be all or nothing. Diesel are
smoothly limited. It ought to be possible to smooth limit stratified
petrol but I don't know from experience because mine just shifts up and
keeps going.

It must be possible, all it has to do is what you would do if you wanted
to hold it there - adjust how far you press the accelerator. I guess that
gets more expensive as it would have to have a bit of intelligence to
monitor how much it had throttled it. But aren't most modern cars already
throttle controlled through a circuit board?

Still easier to just cut the sparks instead of tweaking whats injected.

And easier to indicate to the driver that the system is limiting
the revs in a way that only a technoklutz could ignore.


And you havent fixed the uk.diy in this thread.
