Modular engine not working (Again)

[A7V_SturmTiger]

For those who remember me from my last post, I am quite an amateur with Modular engines, and this time I couldn't find any method of troubleshooting to fix this.

As I built a tank instead of a car, I believe the GBs and Clutches used for turning are interfering with the RPS, and they don't even turn the vehicle either.

The Engine runs fine, and the logic should be as well, so ig just get at it and see what you can find. Anything helps, even if it doesn't solve the problem.
Fyi, most logic parts are in the rear turret bustle, and some are stuffed in the engine bay or under the turret ring.
Feel free to explore the tank itself as well while helping me fix the engine, and give me your opinion on it.

Anything helps, and good luck.

What's the issue exactly? Your thread title claims "modular engine not working", while in the post you state the engine is running fine?

For tank tracks you usually use gearboxes facing away from the engine, to allow more torque on the wheels, otherwise the tank tracks won't start moving due to their hefty torque requirement.

has it got air and fuel pumps, exhaust system and coolant system?

If you are having trouble with your steering, I highly recommend this system by Bruce:

I did kinda state it wrong. The engine is running fine, but something revolving around the clutches or GBs is not letting the tank move. I messed with some settings, and when I turned right, it allowed me to move foward, and turning left locked the clutches. I'm unsure what the problem is exactly, but it should be something with that.

I slapped this boi in there, and it stopped the clutches from locking. Now the engine can get torque to the sprockets, but the engine clutch itself is killing the engine if I even slightly use (Similar to when I had trouble last time). I'm pretty sure from here on out, it's just tuning and fixing the clutch. Thanks for the help!

Okay, now the engine is just the problem. The exact second I upgear the tank, it lunges foward, and the engine instantly stalls. I feel like most people have this problem, but see if you guys can figure anything out. Thanks (Again)

Edit: The Stoichiometric also drops to -1 when upgearing

So the issue is that your gearing is all wrong. When you upshift, you need to shift to a smaller gear ratio, and modulate your clutch. Personally, I would completely scrap the whole engine assembly, and use this, or something similar:

The easiest way to make an automatic clutch is to use an up/down counter with an increment of 0.01 (give or take, tuned to your needs) and clamped at 0-1. On the up node, connect greater than with the rps greater than something like 6, and on the down node compare the rps to a less than with the number being something like 5. Again, adjust to your preferences. When you start moving, the up/down counter will fluctuate as needed to keep the engine above 6 rps (or whatever you set it as.) I've found up/down counters are much more quick to respond than a PID. It can still cause some surging and won't be as smooth as a PID potentially is, but far easier to implement and tune. I have a super simple clutch controller on my workshop if you want an example.

I decided to scrap it like you said, and I copied a different one from a Tiger E, and it works gloriously now (But a tad bit slow). Tysm, because this is the main problem I've had with most of my builds, and was the only part I didn't understand. Cheers!

I am so glad I was of some help! If you need anything to do with engines (clutch systems, ECU's, tank track movement, wheel systems, etc.), I really recommend Uran Wind. He has all the top notch engine controllers and systems. The best part is that they adjust for load and supercharging, so as long as you have the right number of ports, everything will work.

I'm also having new troubles, and you seem like the person who can help with it. Here's the link https://steamcommunity.com/app/573090/discussions/0/4036976796097492491/

Start with a gearbox with the arrow pointed away from the engine, set to 3:1 and 1:1. If you have issues taking off or when shifting, add another gearbox set up the same way. Once you can take off and shift into 1:1 without issue, you can fine-tune them to smooth it all out and add another box if needed. Once your acceleration is where you want it, add a gearbox pointing towards the engine set to 1:1 and 3:1, and do the same thing, shifting ithem sequentially. Keep adding boxes like this until you can't add any more without killing the engine. Then go back and fine-tune each box to get a smooth acceleration curve. I usually use 4-5 boxes total.

You can use an up/down counter and on/off pulses to set up a shifter. Set the up/down to min 0 max of how many boxes you have, increment 1. When you hit up, it pulses once and increases the number by 1. Down does the opposite. On the output, add a threshold for each gearbox. Then for each threshold, increase the max by 1 number. So gearbox threshold #1 would be 1-1, gearbox two would be 1-2, and so on. When the up/down counter increases, it will activate each threshold in order. Each threshold would then be connected to its respective gearbox. At zero, all boxes are off. I would recommend doing this in a microcontroller. Hopefully not too confusing.

Edit: I said thresholds, but it is easier to make it go incrementally using greater thans, with each gearbox being one number greater than the previous. With thresholds it takes more logic to make them work properly.
