Can anyone give me a tip, or explain the logic of the Eng Speed outputs?
I played around with one, and can't seem to grasp the logic behind it. If I set it to stepped intervals, i.e. 1000rpm, 1500, 2000, etc, it seems to switch the output on and off at alternating points, i.e. off at 1000, on at 1500, off at 2000, etc.
If I set the first cell to 1000, and the rest to 2000, the output is on until rpm goes over 2000.
Maybe I was just tired, but couldn't get it to work consistently.
Thanks.
Engine Speed Controlled outputs - HOWTO?
Re: Engine Speed Controlled outputs - HOWTO?
OK, having a couple of extra minutes on my hands in the 40deg C heat today, I played around with this control again, and found it is actually quite easy.
What makes it difficult to figure out is that SCal only shows which speed control band is active, not whether the output is actually on or off. Well, every odd number is on, and every even number is off.
So if you want to switch some output on at 1500rpm, and off at 2000rpm, enter the following:
I think this should also work:
If you want to turn the output on and off throughout the rev range, just set it as required:
This will turn it on from 0rpm, and off at 2500rpm, then on again at 2500rpm and off at 4000rpm, then on permanently at 7000+rpm.

Re: Engine Speed Controlled outputs - HOWTO?
This is a very old strategy and was used for a Ferrari engine with variable trumpets that needed the vsv to be adjusted constantly with RPM to gain maximum torque. It was odd but worked extremely well.
If you simple want an item to turn on at say 3000rpm, then set the first cell at 3000 and all the rest at say 25000rpm
What you have said in Post 2 about On / OFF per rpm is correct
