Why are revlimiters uneven?

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.

My car is an automatic so that is what it does. I never tried putting it
in first or second to see what it does when it hits the limiter.

In my Golf, the selection was only advice from me to the car. If I said "1st" and that was a stupid idea, it would use 2nd. Fun to select 1st when going at highway speed. It dropped the gears precisely when sensible to do so and stopped very quickly.

Two of my bikes have carburetors so manipulating injectors isn't an
option. I haven't hit the limiter on the other bike and just shift at
10000.

Not possible to do that and still get the best performance.

You're getting **** all performance if you've gone over the power curve anyway.

Makes more sense to have a rev limiter and much easier to do too.

And you ****ed up uk.d-i-y in the newsgroup list, you have uk.diy

No, the guy that made the group ****ed it up. How did you notice?

Had a rev limiter on my RS1600 with electronic ignition in 1975, it worked
well at 6700 rpm.

I did not have a rev limiter on my Renault Espace built in 1993. I broke the engine badly. I thought they all had them by then!

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.

It doesn't drop off that dramatically.

After all, you paid good money for them. Then you've got to keep an eye

That depends entirely on how the engine is set up. A turbocharged angine
for racing can easily be delivering nearly flat torque all the way to
disitegration and will develop full power on the limiters edge
