RPS Jumping after Recent Update in Stormworks 

Here I was thinking I'd messed up something with my controller... glad I saw this.

Flywheels are good for suppressing that. Also ensure the engine is getting enough air. None of my engines have this issue.

I believe it's a recent update that intoduced the problem, one of the updates changed the particles or something of the exhaust, so it's probably that that caused this problem.

I've taken over your RSV Altroz. The one I use has the same problem. I've added pumps to the fuel. I've added pumps to the air. I've added pumps to the exhaust. I've added more fuel. I've added pumps to keep the fuel tank pressure to 30. I messed with the programming to limit clutches and rpms. Tried disconnecting a motor. I've done just about everything I could think of and just decided to live with it. Lost 5+ knots to the max speed. I was hoping you would come out with a video addressing the issue and I'm glad you were also having the same problems, but also sad that it's a thing now. At least I know it's not just me. Awesome stuff by the way. I love how I can take parts off of your other, newer craft and incorporate them into other builds. Such a fun game and the creations you've made make it so much better. Thank you.

I know for the 5x5 pistons you need more than 1 exhaust manifold per piston. Like 1.25 or something. I havent figured a specific number but its less than 2 and probably less than 1.5. That is for running at 20 RPS on a custom engine. There is on the custom engine details a % exhaust efficiency. If exhaust gases are stuck in the engine then fuel-air mix can't enter. Options then being: 1) add more ports or manifolds (the end tube part) on the exhaust pipe (1 pipe could take the volume its the port that was the choke point) 2) consider adding a pump to exhaust if you don't want to add many ports/manifolds.

Also love the videos keep up the amazing work 454ss

Had the same issue with large and medium prefab engines on boats I built and am using in the game for a long time now (2+ years). Turns out the engines were running out of air (engine intake air pressure was getting really low) due to some recent game patch (I vaguely remember the patch notes saying something about a fuel rebalance). I had to use two of the large 4x3 fluid ports per engine as air intakes to be able to run the engines at full power again.

I have been fiddling with this problem for too long now, but i have the joy of finding the solution..! I can replicate the problem too the exact point, with the infinate fuel fixes everything solution. But it turned out it was the air all the time.. I have five medium (pre built) engines in my boat and they had enough air intakes but some of them had combined piping. When i give them seperate air piping (5) and two ports on each engine (10) everything works like it should. The fluxiating rps disappears and the power is back.. (..The medium engine only has one air intake, but neads two ports to feed it for max potential..) Don't know if it is intentional or a bug, but i know you will figure that one out. Really hope this can help.

flywheels works like capasitors: evens out the RPM/AC

This might just be me, working as a software developer, but I really think we need a guide on how to properly report a bug in game. The original post is too vague to get any useful information out of it to pinpoint what is causing the bug. What is bothering me the most is, that they replied, that the information given is too vague and asking him for an example ... with no reply. When tickets like that come in at work, we are instructed to maybe ask for an example again or close the ticket after a week because there is nothing to gain from apart from the information that there is a bug. Again this could just be me as a software-dev, but i at least have the hope if we can establish just a few guidelines for reporting a bug that this could improve bug fixing ... give or take what the dev actually do with the info. 1. If you find a bug, report it 2. Be specific, no vague statements like "at a specific rps". Something like "In my case at around 25 rps" is better 3. If Possible, give/add examples on how to recreate the bug. If this is a bug, like in the video, upload the vehicle to the workshop and add that link to the bug report. Otherwise, picture/videos etc.

Hey 454ss just a heads up ALTA is a real Grand Rapids Michigan fork Lift rental company just figured I’d let you know so you could have an early warning if they decide to sue you for whatever reason if they even can Edit: and they use an incredibly similar red to the red you use and an incredibly similar font

It may also be on the air side, infinite fuel also allows engines to breathe infinite air as far as I know

random idea that might fix it. place some sort of gas relief valve from the fuel tank to the interior of the ship. it might be a problem with the pressure update as while pulling out the fuel you end up creating a vacuum, and the game has no idea how to deal with it so it just freaks out. just an idea. i didn't try it myself

How did you connect the pumps in 10:32 without having to go back to the ignition. Is it some sort of key combination?

I had similar problems with the custom fuel tank before the gas upgrade and fixed them using the following chain of connections: custom fuel tank -> pump -> tank (enough to briefly supply fuel to the engine) -> engine. Also you can try to add new filters

Could be the issue that the fluid ports are on the top of the tank instead of at the bottom. So then the fuel is more difficult to pick up

if you limit the throttle to like 95 % throttle it will stop it ( atleast of me )

Soo i think he made this Video Because of me XD... Cuz I was Complaining to him about it in his ECU too XD Sorry 4544s.😅

In my game it's not happening when I am playing in career so I don't understand why too

I’m not sure if it’s the problem but maybe it’s cause your drawing fuel from the top of the fuel tank instead of the bottom

I saw this too I was making a modular engine controlled by a pid and I thought it was just my pid settings lol i guess its just a stormworks thing

I'm having this issue but the RPS keeps jumping even with infinite fuel on.

I need Help, why does my RPS decrease the longer i hold W if i release and press it again the RPS goes up again

Torque I belive

Yeah no, the RPS spazzing has been a problem in this game since day one. I'll have a creation that works perfectly, I'll change nothing, and then one day it suddenly just starts spazzing out. Always eventually happens to like all of my builds. Sometimes the issue suddenly goes away when I come back to the game after a month of not playing due to being fed up. My hunddreds of hours in the game has been trying to design a perfect ECU that eliminates all oscillations, and just when it seem I've finally got it solved, the issue suddenly comes back for seemingly no reason.

454, do you have a fuel pump feeding the engine? Or are you just letting it suck fuel? You might want to try using a pump with a fluid relief valve so it's not pushing gasses it picks up from the tank. FUEL TANK > Fluid Port > Fluid/Liquid Relief Valve > Fuel Pump > Pipes > ENGINE Keep the fuel line pressurized. I haven't seen a peep of this behavior.

Day 3 of asking for a tutorial on big ballast tanks

Can you make a doggie bay cer

@454ss_gaming Your engines are sucking gas and fluid from the tank since there is no fluid filter on the fuel lines to prevent gas from traveling up the pipe to the engine. There is no "In Real Life" in stormworks regarding fluid port placement for fluid or gas. Ports suck everything on the tank regardless of placement. Additionally now you are free flowing "Atmos gas" into the tank by having a gas filter on the system so you feed the engines stuff that should not be there. Quick fix put a fluid filter exactly behind the fluid port on the tank lines to the engine as to prevent gas from reaching the engines. New features come with new challenges and it is not the developers fault that many creators like your self have to revisit creations. Correcting builds to accommodate new features added to the game is going to happen regardless of the devs best efforts unless they start to nerf stuff for the community. You must remember that the challenge of stormworks is to learn and build as you progress and if you nerf all the components it will lose most of its charm and make the game mundane. The challenge to learn and create is what made the game great in the first place. Creations will break and become obsolete with new features coming out. We could argue that the feature is a bug and vice-versa but teaching your followers to fix broken old stuff is also a viable solution and a positive one in spirit for the stormworks community. Best wishes and I hope this long rant helps you.
