Customisable, fully automatic Lua gearbox for boat

Edit 2025: Lua code is a piece of spaghetti and it's full of workarounds.
But it kinda works by itself.

Customisable, fully automatic gearbox on Lua, can be used for boat.
You can see how it works in practice, here https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=2176155756 or here: https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=2181402367
It works about the same there.
Some info about inputs and outputs:
Gear - only for sending information to your dashboard (from -1 to 4);
Pilot - pilot/driver seats have an composite output, just put is here.

Short description: do not make any changes, connect nodes and it should work.
If you want to customise, read instruction.

Settings:
The main settings are outside of controller:
Target RPS: Idle RPS to get without normal throttle from lever;
RPS gear up: RPS to shift gear up;
RPS gear down: RPS to shift gear down;
RPS to drive: RPS to turn on 1st or rear gear;
Speed ​​with full clutch & Value to add to speed (for clutch): used formula for clutch - Speed + "Value to add to speed (for clutch)" / "Speed ​​with full clutch" - you need to config these values to get good clutch work;
Target RPS max throttle: maximum throttle to get Target RPS;
Min throttle: minimum throttle when the engine is on (this and the previous value should be very different from optimal for the current conditions and can be found in practice, for example, 0.08 and 0.09 are optimal for engine, but 0.05 and 0.12 are set here;
Use Park / Drive?: - use "Parking"? (Stop/Start moving) from driver hotkey (default is 1) or switch gears all the time;
Use throttle lever or WS (reset mode)? - usually on boats we use throttle lever, but changing of this option allows you to use W/S buttons instead of lever. If you don't need lever, all nodes "Throttle lever" may be deleted, and put W/S directly.

Additional settings in the controller itself:
By default "Engine on?" is On/Off input - red arrow on screenshot - it can be configured manually;
driver's seat buttons (hotketys) - info about stop/start - yellow arrow, hotkeys can be configured by changing channels (from 1 to 6).

Gearboxes are configured like this:
Rear: none,
1st: none,
2nd: 1st gearbox,
3rd: 1st and 2nd gearbox,
4th: 2nd and 3rd gearbox.
It can be configured by editing in Lua script - for all gearboxes there are an line with gears set (Gear 1 work, Gear 2 work, Gear 3 work), G1 is forward, G2 is rear, or in the Up / Down counter outside of script by editing of number of gears.

Good choice of gearboxes - better work in practice )

I hope my description is understandable.

You can use microcontroller in your creations and configure it, but save link to original.

Sorry for my English, if it's bad.
Enjoy!
