I never thought I'd have to watch a video on how to tune engines but I'm glad that I have to.
The new turbo system is really good, you can make perfectly flat torque curves!
Yeah, you can set up some beautiful engines with that now :)
@@AutomationGame thank you guys very much for the continued dedication to your craft. We love it, and stand behind you ❤️
You could on the previous version too unless you mean at the redline and idle too
@@stephenmartin5766 No.
The ENTIRE RPM range is flat
@@ghoulbuster1 nice. In previous automation I have had it flat from about 1000 or so all the way to within 300 of redline. But both ends were not too far down in torque but not flat no
This helped a ton, mostly in the "Just because it's not perfect doesn't mean it's bad" department
Yeah, it isn't all that tough to make a really solid engine :)
Hot turbos in your area! As someone who has never fully grasped the intricate it's of turbo tuning, this is a very helpful guide.
I just chuckle at the thought of turbos and carbs. I know they existed, but wouldn't you just be better off with fuel injection for the same time and cost additions? Lol just a little funny thing to me.
Turbos and carbs... are a bit special, yes :P either mess up your off-boost engine, or your on-boost engine xD your choice!
@@AutomationGame how well does mechanical injection work with turbos?
Watching both tutorials just confirmed my love for NA engines... 😵💫
Love the new update! Would love for the boost pressure (PSi) slider to be more accurately adjustable instead of going from example 5Psi and the next click takes it to 8Psi and we can’t get in between
Considering it adjusts by 0.1bar each tick, and 1 bar is 14.7psi, it should change by 1.47psi each tick.
Yes, we're looking to halve the step size, that will help! :)
Yeah thats been quite a big problem for max power tunes, one click your fine, next the engine has left the dyno room..
That means you're too close to the limit, too though! :D
@@AutomationGame the power is great its just it seems quite low boost for said power.. 8300hp on 28psi or something?
Some of my more extreme pre-update engines blew up after the update 🤣, managed to get them to work again and making more power than they used to have. Also I feel like after the update I can more accurately replicate the engines from the malaise era of US car manufacturers, a.k.a. gigantic displacement engines that make hardly any power.
Yes, in old Automation they were basically making their gross power numbers as net haha
I usually just move sliders around until I can get the best efficiency and reliability out of the desired power numbers and curve, but I want to improve thermal efficiency at desired RPMs, so I can really make the best engines I can.
Thanks!
As someone who has always just accepted most of what engines do as pure magic, this was really educational. On another note, could you make a TH-cam playlist for game tutorials by this channel?
Glad you enjoyed it, we will definitely do that!
It took me awhile, but I now know that the exhaust makes the compressor act strange.
With the timing map I was always thinking of "It's not about size. It's about the motion in the ocean." 😂😂😂😂😂😂
everything is fine and i do love everything,
but how can i know how much boost am i running? before the revamp there was a yellow line for it. now i don't see it no more so i just keep guessing i'm getting the full 2.5bar i'm trying to run or it's just 2.5bar limit and running at 0.3~1.2 bar.
A question about making things bigger or smaller, wasn't there supposed to be a visual adjustment as well, like when it says making the carbs bigger or smaller i was almost expecting the model to change size.
Unfortunately that becomes a piping nightmare :( so you have to suspend your disbelief.
Just a note. Powerful turbo engines are obviously alot more... explosive.
Just wondering if its a bit too much since ive got engines blowing up at sub 30psi and ive heard of racing engines getting up to 90 odd psi? ive built a few max power engines and it becomes apparent that max power is limited by how much boost the engine can take and obviously the size of the turbo exhaust etc.
That being said i got 2080hp out of a 2ltr I4! And almost 1100 out of a 1ltr I3!
question: in aspiration setup details I have only 1 turbo and not the icons "stage1 and 2" somwone nows about update or mod ? pls (i'm french so sorry for my bad English)
The UI is prepared for 2-stage forced induction, which is going to come in the second milestone of this update cycle.
I'll soon have a computer powerful enough for Automation/BeamNG Drive. I can't wait to get started, but I've got some questions. I know that Gasmea is a lot like the U.S., and Fruinia is a lot like some European nations (France and Italy, I think), but which Automation nation is more like Britain, or Japan, or Germany?
I have the game but when i go to turbo options it doesnt got that mush options how do i get it looking like that ?
Sounds like you're on the 4.1 version of the game, opt into the 4.2 beta via the Steam Library!
Do the turbos in this update have the antilag technology or they replicate more the 80s turbos?
You should be able to replicate most turbos in this update.
trying to find what you have on your screen but i don't even see the 4 graph view when trying to design an engine, do i have to play more into the game or my version is outdated or something? downloaded this game yesterday from steam
Hey there, welcome to the community! For this content, you need to opt into the open beta version; to do this, right-click on Automation in your Steam library, then go to Properties. Select Betas, then from the dropdown menu, choose "openbeta - LCV4.2 Opt-In Alpha". Automation will need to update, but you'll be all set!
@@AutomationGame got it, thank you!
Sorry for the dumb question, but how on earth do you present so many different graphs? I can just see graphs for power, torque and efficiency.
What happened to the compound turbochargers? Do we still have to wait for that?
Sequential turbos have been moved to the second tranche of the Supercharger Update. We moved them because it has been more than a year since the public version got an update, and it would have been a couple of more months wait, for just this one thing.
How do you get extra tuning options for the turbo
You need to opt into the open beta version; to do this, right-click on Automation in your Steam library, then go to Properties. Select Betas, then from the dropdown menu, choose "openbeta - LCV4.2 Opt-In Alpha". Automation will need to update, but you'll have the latest version of everything then!
I recently dug into real-world turbo tuning, and wanted to apply some of the knowledge in the game, but the 4 sliders aren't intuitive.
The top two sliders are labeled "Turbine Inducer size" and "Turbine Exducer size", but the ratio implies compressor inducer and exducer. But it can't be compressor dimensions since the third slider adjusts the compressor trim?
I believe turbo tuning in the game has some more work involved at least in the labeling of the parameters.
Effective compressor size and effective turbine size, then a tune slider to affect both compressor trim and turbine A/R. The modeling is pretty good I'd say, not sure what is confusing about it apart from this not being an easy topic.
Is it possible to get rid of the compressor surge problem when running a 331cc I3 making 666 hp or is it impossible?
It is, but you're running with such narrow margins at that power level that the window of making an engine that doesn't just explode immediately are very small indeed!
Awesome! When we gonna get stage 2 and the supercharger? Lol
We have to finish the Ellisbury Update first! xD
@@AutomationGame keep at it! You guys are doing a great job and appear to be on the right track! Would in car data from a real 6 second drag car help you guys in any way?
Hello!
Absolutely loving this build!
Just wanted to inquire about some observations. I am noticing that I am having to run much lower compression versus the real life engines. I wanted to recreate the VW EA888 Gen 3 and I found that I had to run much lower compression vs their rated compression. (I get the message stating the engine has to run to pull too much timing)
It could also be that maybe i'm still not tuning properly, just wanted to throw in my two cents.
There definitely was that issue to a significant degree before our second hotfix, since then all fuel systems have been buffed in terms of octane requirements. Do you still have the issue now with the latest update? If yes, by how much roughly? Don't forget that tuning compression to produce the highest peak power is not desirable in most cases. :)
@@AutomationGame Hey, thanks for responding. Numbers are looking much more inline! I'm not generating the same exact numbers of course, but it seems I no longer have to run unrealistic compression ratios to get a realistic engine. You're fast!
I dunno... Something seems out. I've had a brief look at a couple of my engines, and the new calcs are making me resize exhaust systems to extremely large sizes I never seen on a production car, or in the (properly) tuned community for engine type, size and power output (almost double in a few cases).
Hmm, hate to say it - but your 2.0l engine is one such good example. 76.2mm (3" exhaust) - ever seen a basic 2.0L 4 cylinder turbo engine come from a factory making a healthy 152kw (205hp) with a factory exhaust that big? Something in around 2" to 2.5" would be normal. Maybe a tuner might go 2.75 if they lightly tune the engine but otherwise leave the engine mostly stock. I usually see a 3" to 3.5" exhausts used on a properly tuned 4 cylinder engines making 350-400. Yes, I've also seen people putting 4 to 4.5 on there sub 200hp 4 cylinder engines as well, but lets ignore the over compensating crowd.
Huh? Really almost double? I can see that they might be a little too large, yes. Just as an example here, for a 276 kW engine I'm running dual 2.25" exhausts or a single 3.5" exhaust for optimal flow, that doesn't seem unrealistic? Using an exhaust size calculator I see that 2.86" would be recommended for that power. I'll see if that can be adjusted so that it is a little closer.
No - 276kW (370 hp) is about right for 3.5" exhaust. Hmmm... 😞
My little 2.0L motor (210hp I think it was) went form a 2 1/4 exhaust to a 3.5 in game. Thors hammer (my ultra advanced '20 1.6L V6 turbo) went from dual 2.5 to dual 4.5 for the same power... Hmm
Well, there's a lot of stuff I need to look at with these engines on my end - maybe I'll try creating these from scratch to see if moving from the last update to the new update these engines just didn't update right. I do know a number of things are now really out of wack on these 2 engines with this update, so time for a retune.
And yes, I do like the new tuning graphs.
Anyways, thanks KillRob - I know you guys are putting a lot of blood, sweat and tears into making this game awesome. :-)
Alright, thanks! :) Let me know if you find any tendencies we should act on in terms of tweaking. Cheers!
Are you considering to add superchargers? if so, are they a long time away?
After we're done with the 4.2 development cycle, work on the Supercharger Update begins in earnest. In fact, our artists are already hard at work making the assets needed!
@@AutomationGame awesome, I can wait to make a big blown engine
I just finished making a turbo 80s car. It's is tuned to be like a road legalized racecar. But at low throttle input it gets really really sputtery and backfires. I was wondering if I did the tuning wrong or if that's a bug.
Nah you might need to make yours gears shorter, also try a smaller intake, smaller exhaust and lower cam profile. try each by itself and see if they make improvements, then combine if you need.
@@Sk0die it was a glitch in the game.
Really mad that in Beamng my turbo engines stumble and backfire at part throttle even though my fuel maps look good in automation 😢
there's a bug in the camso_engine.jbeam file. I discussed this in the steam forums on how to fix, but I'll copy and paste here.
"wastegateStart" and "wastegateLimit" are not correlated to Automation values (so change those first)
In the old version: "pressurePSI" is only negative at 0, and has (increasingly) positive numbers at each increment until it reaches the "wastegateLimit" value at a certain turbineRPM limit. The new version has negative numbers at positive turbine speeds, which causes the part-throttle hesitation and flame-throwing. (fix that next).
engineRPM, efficiency, exhaustFactor - the old version is exactly the same except the new version's efficiency values are not normalized to 1 (where 1 used to be the highest value, it's now 10, though I have seen values of 4, 5, 6, and 8 - depending on the boost you set in Automation). (So I'll take each of those values in the new version and normalize it to a maxiimum of 1. So if the max value is 4, divide every efficiency value by 4, if the max value is 10, divide every efficiency value by 10 etc.)
Eventually, they'll fix this, but in the interim that's the only way to get them to function properly.
@@ragingbull94mtx thank you that makes sense.
On the V12 I was just sitting waiting for him to realize that when you stick a turbo on an engine it defaults it to single exhaust. He spent all that time trying to figure out how to tune it and never caught on.
Uhh, what? I didn't have to spend any time on that because I just start with making the exhaust super large before I put a turbo on it, so large that a single exhaust doesn't make a difference.
So you are saying there is no performance difference for twin turbos between a single large exhaust and two properly sized ones? While the single might make the same peak power, the dual exhaust should spool up faster, especially if you have something like a properly tuned x-pipe (something not in the game right now).
No, I'm saying that I make the exhaust stupid large first, don't care about it, set up my turbo, and then once I have a functional turbo make the exhaust the correct size. A correctly sized single exhaust is about as efficient as a dual exhaust of equal flow.
A few things im waiting for @killrob
You confirmed that we will get to make compound boost set upse such as compound / sequential turbos . Also supercharger feeding a turbo
What i was wondering is if we will get that in the twin turbo set ups also
Like if we have a v6 with twin turbos
We will get to put the first stage as a supercharger .
Other than that some car brands like hyundai and volvo make fancy names such as N grin shift for what is esentially antilag so that their boosted engines dont loose much turbo spool between shifts . Will we get antilag in automation. For alot of my highly boosted builds the cars get alot of lag when spolling the turbo in between throttle inputs
The other things i was wondering about include getting twin exaust exits for engines that have one manifold. Most car companies use dual exits for 4 cylinder cars for example .
Lastly
I have modded hybrid cars in beam ng in the last useing some of their electric motor codes and integrating them into an existing jbeam for the automation cars
I know how u like to do things but all of your features such as turbos started off unrealistic unpollished ect so can we get a rudimentary electric motor set up . I know your easily capable of making that feature integrated if i can do it by moding j beam files
All i want is
Add a section after transmission called electric assist .
And it will just add power and engine braking to the transmission and integrate with what ever powertrain selected
So we could make a fwd car and then put an electric motor in the back
And in that same section give us a weight added proportional to the size battery and amount of motors
Its 2022 everything is hybrid nowa days
Mabey theis will be expanded to include visual elements and fully electric cars but for now i dont think anyone cares would just be cool to be able to make hybrid cars or even electric.
If you guys even add it as a dlc would mabey make you guys some money .
I think new stuff that you didn't intend to add initially if you do them as dlc it will be worth it
Like if you made desils
Or wankel engines
A V6 would be able to have supercharger + twin turbo, yes.
No antilag in Automation, no.
Dual exhausts for single header: maybe
No electric car stuff is coming any time soon, we got more important fish to fry :) the game ends in 2020 for a reason!
@@AutomationGame okay make sense . Do you think there will be a possibility of adding electric stuff in the future or will u just keep updating the car formats so that in the future people who mod stuff like myself can add electric motors through j beam files
@@AutomationGame do you think we can get cvt gearboxes
@@AutomationGame beam ng has some nice turbo sounds and exaust sounds for their cars . And sometimes i change sounds like blow off valve and exaust and backfires to something new . Do you think we could get more options for tuning the sound of our cars ?
Like if we have cars with a single turbo running 40 plus psi
Im sure we would want a nice turbo flutter sound
Electric: probably as an expansion after the game is done.
CVTs: nah, too much of a hassle unfortunately
turbo sounds will get some love eventually, yes.
Thoughts on 16 valve DAOHC such as the 1ZZ Toyota engine?
How many engines did have that valvetrain design?
@@AutomationGame not loads. I wasn't sure how complex it would be to add it as an option however. I know that many small displacement engines use it such as motorcycle units and a few car applications/ racing. They were a way to get higher rpm from engines in the old times; but I do understand if not possible 👍.
Thank you for responding and I love the update.
However, as a quick aside that I just remembered; I don't understand octane margin yet, the question mark doesn't present me with any options and I haven't found a benefit?
i am missing the sequential turbo options
Sequential turbochargers have been delayed to the second update in the Supercharger Update cycle...the reasons for this will become clear soon ;)
wow
My game version is very off from this one, any help?
Opt into the openbeta via your Steam Library
Can i play it in beta?
Sure, just need to opt in via the Steam Library!
Still waiting for superchargers
The wait grows shorter every day, friend...we are working on them behind the scenes as we speak!
I feel it is appropriate while on the subject of turbo engines, that im just going to model an make a mod, ive been waiting long enough, purchased the V16 add on to support you guys, and one of the most influental engine designs is still left out, with examples of popular vehicles being
Ford escort diesel
Ford ranger 2.3 mistubishi and perkins diesels
South american duratorq rangers
Nissan pathfinder diesel
Vw line of diesel cars
American half ton 6 cyl and 8 cyl diesels
3/4 ton turbo diesels so on
I appreciate the work you guys put into the game but im just tired of waiting
Finally!
Edit: First.
no
@@o-owow9612 yes
@@magictoffee7066 nope.
I made a 509cc inline 5 whit 682hp.
The first car I made was a 3.6L V12 with like 500 or something HP that might have not worked on beamng. The second was the poler opposite with a massive carbureted I4 in the 1940s that made less than 60Hp.
@@jwalster9412 Haha nice.
