@dragonmen002 you can use pid for find exact idle rps spot)

the decimal i mean like this .004202 but with multiply of 20 so it quite close to 19.5 rps but i was doing trial and error to closely to 20 as possible but not quite perfect but that ok

for the rps i just put a very small amount of number of decimal for example .004202 that bring me to 19.5 rps it quite close to 20 rps so that what i did so no need pid at all :D

@dragonmen002 yep it's exactly why this controller exist. For this moment i dont have exact solution for RPS, but iam almost get this. If my thinks correct, i make universal pid-less RPS control in near future time.

yea i was just modify from throttle node wire line inside the microcontroller into the math logic for preset idle and little preset tune offset load when it apply throttle under load it might help depend most of people need little extra power but still preset idle you set to but it just little offset when it apply throttle but when you let go throttle it no longer offset and back to idle set that to for example 20 rps, or having a option to overdrive so it not limit rps so it just full blast to 60 rps. and also add a starter to start the engine and automation turn on the cooling from electric radiator and option of add a pump for cooling system. but it take me while to trial and error to get where i want. i done modify other microconroller from other steamworkshop but it quite hard to tune to other engine type so i was looking for that are easy to already pre tune no matter what size or shape of the moduler engine

@dragonmen002 Yes you can, but keep in mind, you must keep unmodified delay lines (Composite -> Read channel -> Calculation -> Output) here a important time/tick syncrosization!
You can integrate any your solutions into "C" node (main throttle) on both functions without fear of broke delay lines.
Also i has planned a next controller what bind fuel flow and revolution acceleration.

idle its easy on this controller because fuel flow driven) just find your fuel throttle value.

i was wondering if that ok to modify of your ecu add into of idle set? along other logic in it?

@DarquosLeblack yep, it's exactly for what it was designed

Just wanted to say how awesome this controller is, especially as a basis for self-designed engine control ^^

Minor but important update. Now i know how to calculate RPS from cylinder size, fuel flow and throttle. Path for development 2x2 contorller with RPS regulation opened.

cool

Major update! Now air throttle control taking in account main throttle value, what remove divergences on air throttle while main throttle changing.
