TLDR description:

65cc Stroker engine, ready to "power" everything except your dreams

=============================== Specs ===============================
Engine vitals: 1cylinder, 65cc stroker spring engine

Engine stats:
Idle : ~105rad/s
Redline: ~315rad/s (limited, if you remove it, it goes higher)
Horsepower: 5hp @2610 RPM
Torque (NM): 19 @ 2050 RPM
(dynoed with The Linkage's 'Engine Dyno v1.5r1' (which you should totally check out btw))

============================== Controls ==============================
Enter : Start/stop
I: Throttle resetter (toggle)
Up arrow: binary throttle


========================== Tuning with this ECU ==========================

Each of the different colored (and un-colored) segments around the ECU laser mean a different
spring map, you can change the spring map to whatever you like (within reasonable limits) in the script menu.

You can right-click the flywheel and change the "rpm" variable to be divided by a bigger or lesser number
this will result in the ECU thinking the engine can go to a higher or lesser RPM, therefore making the mapping have more or less spacing.
(poorly written, excuse me for my english, i think you know what i mean)

DO NOT change the spring constant directly by right-clicking the spring, as this will make the spring
non-scripted. which means you have to do Step 3a of my manual to get the spring assigned to the ECU again

BUT YOU CAN change the spring's damping from the right-click menu to your heart's content.
Same goes with spring length, if you think my 5hp tune is done poorly

========= placing engine in another save tutorial (copy&pasted from the save) =========

PLEASE NOTE BEFORE USAGE:

This engine is comically small in relativity to most other scenes, powering bigger contraptions/cars/bikes/whatever will require more oomph to do so, consider using my VSC V8 spengine if you're having any issues with power (you're taking a 65cc stroker engine so i doubt you're gonna use it for that). The engine's ECU has to be right side up all the time or else the engine will not work as intended

If you want to run the engine without the ECU for whatever reason, type "scene.my.th := (number here)" for the spring constant, and type "scene.my.damp := (negative number here) for the engine damping rate (higher rates = more torque but needs way less constant to not explode.

Instructions below also apply to no ECU configurations (if you want to run the engine at full tilt).


1. type this in the console while in the save you're trying to put his engine in:

sim.limitangvel:= +inf

2. set the simulation frequency to 210hz

3a. put this in the ECU lasers "rotation" in the script menu:

{
scene.my.rpm - 0.3
}

3b. put this in the engine spring "constant" in the script menu:

{
scene.my.th
}
