Coolant clutch was used to drive cooling loop to keep engine at desired temperature prior to cooling changes a long time ago, nowadays it is best to keep cooling at max as temperature doesn't matter as long as it is below 120°C.

what is a coolant clutch ??

So underrated

for me when adding some resistance to the engine it starts to spazz out and alternate between 8 rps to 4 rps very rapidly

ah well then ill just make something myself. cooling is weird anyway soo

Could you share the blueprint with me so I can take a look. I stopped bothering with cooling loop control after thermal rebalance because I did't think it was that useful as for me it was best to keep the engine as cool as possibile to maintain maximum power margin.

my coolant clutch node never goes up why does that happen?
my engine is at 87°C

@imPyre if you have any questions regarding inner workings of the controller feel free to ask here, in a PM or on Discord. I decided against lua because a controller using logic blocks has a bit shorter delay on PID loop.

This is by far the best modular engine controller on the workshop. I've been working on building a Lua-based microcontroller and I've been struggling. I subbed to several for some ideas of how other people have approached the problem, and this is the best I saw. My only source of frustration is that *none* of the controllers use any Lua code... and I have a hard time wrapping my brain around all those logic nodes lmao.

+A very well done my man, only controller that currently works flawlessly with 3x3 as far as ive seen.

So mechanical pumps are... wonky to say the least, and start going crazy beyond 20 pressure on a single-cylinder 3x3 engine attached to a large generator with the small impeller (I have not tested the large impeller).

What works;

Large electrical pump regulated to 60 pressure.

Small electric pump regulated to 9 pressure.

Belt-driven impeller (7.5 pressure) Don't bother with trying to regulate the pressure.

Note, electric pumps work at all RPM ranges, while mechanical pumps need lots if adjusting or can only be used effectively within a certain RPS range; otherwise, stuff starts freaking out, hence the need for number stabilizer microcontrollers to dampen the numbers otherwise the engine constantly surges at an extremely high cyclic rate. I'm sure that a flywheel would help with this.


In the end, for best efficiency, just put a fluid pressure sensor on the intake and don't bother with supercharging beyond just messing around and going stupid fast on diesel engines.

The best Controller I've used so far but is 20 pressure really the utmost limit when supercharging?

What do you mean?

is there anyway to xml edit that?

Above 60? No, it is modular engines limitation.

is there any way i can increase maximum RPS?

Amazing! Currently Building a Plane and will Link this MC in the Credits When it goes on the Workshop.

Successfully implemented. Even with my misunderstandings, it's a way less headache than manual adjustments of that modular crap. I can only hope there would be differences in engine sound, as it had been with stock engines

Nevermind, just noticed the throttle lever max limit have to be above 1. Had missed the desired rps/throttle instruction

Both example engines work just fine for me. Can you share a blueprint showing the problem?

Doesn't seem to be working on modular engine preset

How do I make the engine cool down? The new update broke the cooling on the engine I think.

how do i configure the engine to have a slower, safer, and more steady acceleration
Reduce the speed of a lever

I didn't understand how it works, tho i've tried, but it works nicely :)

ooh ok, thx for the answer !

Another possible source of issues is exhaust flow limiting performance. It can be remedied by adding more exhaust or using pumps to reduce exhaust pressure.

1) Engine can't turn at that speed with that load. Typical symptom is integrator running all the way to 1 unless it kI was set to 0.
2) Large engines with central air intake can become airflow limited. Typical symptom is low AFR at some cylinders.

Both of those can be more easily checked in direct throttle mode.
In case of flow limit causing issues engine will work fine at low throttle values but increasing throttle too much will cause some cylinders to lose AFR while few remain at or near set AFR. If this is not an issue the other problem can be observed if engine can't reach desired RPS at full throttle.

I have an issue that is about the rps, i have set it to be 34 rps when it reaches 25.8 rps then it first goes over that but then it slows down to 25.8. What could be the issue?

kP, kI, kD are RPS PID controller's gains for respectively proportional, integral and derivative.

how do i configure the engine to have a slower, safer, and more steady acceleration

What is KP?

Updated the controller to be compatible with e0.0.44+

Would love to fix it but its way over my league.

Thank you, apparently they changed relation between intake pressure and air volume.

Loved it but. Does not work after latest experimental patch

extremely useful for forced induction

Air intake pressure sensor.

what do we connect the pressure node to?

Connect at least: fuel and air throttles, desired RPS, RPS and Pressure. If RPS becomes unstable tune the PID using kP, kI and kD in controller.

how do you use this

Could you please send me a blueprint of your setup. You can find me on official discord under the same name.

im trying to use this ecu to work on a f8 3x3 engine but the engine will only stay at 16 rps any help?

I was indeed smoothly disengaging the clutch; not instantly setting it to 1.

I also identified the reason for engine idling after being shutdown. It is caused by the integrator outputting its last value after shutdown which means output throttle might be non 0 after shutdown.
The easiest fix is to add "*z" in function blocks right before air and fuel throttles and feeding them 1 or 0 on z when the engine is on and off respectively, this will effectively set both air and fuel throttles to 0 killing the engine.

Peekofwar could you please send me example of the stalling issue. My testing indicates that modular engines have extremely low inertia. For example jerking (clutch instantly set from 0 to 1) 2 7x7 wheels causes ~90% RPS drop on my test 6 cylinder boxer engine. Unfortunately you have to engage the clutch smoothly not to stall the engine. Setting clutch to 1 only after output shaft reaches 3 RPS works too.

Found a bug with the controller: If you turn off the controller when it's running, it won't kill the engine, but instead will idle around 327 RPM (about 5.47 RPS) despite receiving no target RPS input.

plik wyślę na discordzie

Dobra tak, zrobię i proszę o plik zwrotny z poprawnie działającym silnikiem ok ?

KermittingSewerslide all connections are described on the microcontroller.

Can you @ me with instructions on how to set this up properly?
