Modpack Engine Dyno
An engine dyno which only uses the modpack and is utilizing PID to find torque. Also includes value averaging.
If you want a dyno that offers a far more advanced UI, especially for its graphs and if you dont mind extra lag too much, you can check this one out right here:

For those who dont know how a dyno works or who havent seen this ever being made in sm, this device is made to measure the 3 values of your engine/motor. It does so by connecting the output of your engine to the input of the dyno and by it applying resistance until it hits 0 rpm (or the set target RPM) at which point it must have hit peak torque. The torque of the resistance can then be directly outputted as engine torque and together with engine speed the power can be outputted aswell. As its applying torque and measuring speed, a dyno graph can be drawn, representing the torque and power curve of your engine. It is utilising the modpack radar and trackers with custom positions to make this work at such a small scale (3×3).
The way to measure torque in sm is by using the smart engine as resistance and outputting its torque value directly. It is assmued and pretty much confirmed, by the way devs do units ingame, that it has to be metric torque.
Peak torque & power values are automatically found by the dyno, but may not be 100% accurate, due to them being taken from smoothed torque and power and having inerta. This can easily be combatted with the AVG value, described further below.
Another important detail is to never dyno engines at physics below advanced. Depsite my dyno being mechanically designed to easily cope with it, the smart engine bearing will be a lot worse in terms of transmitting torque and hardly function. This makes it pretty much useless.
Front Display: Includes the main readings
TRGS "Target Speed" – This adjusts the speed at which torque and power will be measured at (0 by default)
Radar Piece – Displays the dyno graph (detected top speed on the left, target speed on the right and it will draw 9 actively updating dots for both torque and power, their colors designate which is which)
Main Engine Values – Displays values from whatever display mode you have selected (explained further below)
Red Light: Engine stalling light (will light up when your engine stalled)
Yellow Light: Engine speed finding light (will be lit if the engine has not reached top speed and/or if the input direction has not been determined)
Cyan Light: PID tune light (will light up when the PID values have been manually changed with the SMP value)
RPM – Engine speed in revolutions per minute
DPS – Engine speed in degrees per second
NM – Torque in newton-meters
FP – Torque in foot-pounds
HP – Power in horsepower
KW – Power in kilowatts
Rear Display: Includes various options
SMP "Speed Multiplier" – Adjusts how quickly the dyno counts up torque (1 by default, PID multiplier)
AVG – Adjusts inerta for the main engine values, to create averaged numbers (100 by default, 30% of this value for torque)
DSP "Display Mode" – Will change the main value display on the front to one out of 5 modes. These are CRT "Current Values", AVG "Average Values" (utilises PID inerta with the AVG value), PKS "Peak Speed Value", PKT "Peak Average Torque Values" (primarily useful to see at what values your engine stalled) and PKP "Peak Average Power Values". The default mode is AVG.
Orange slider switch – Disables automatic target speed adjustments for high torque engines (important to counteract the issue of torque scaling infinitely, is applied at all times as a function of outputted torque)
Red exclamation mark switch – Disables stall detection and its automatic deactivation (may come in handy if you see the red light appearing and it getting in your way)
Yellow timer switch – Disables automatic restarts only happening after it has reached top speed (may come in handy if you see the yellow light stay on forever)
Gray crossed out screen switch – Disables the dyno graph and its calculations (useful to reduce lag a bit)
Gray memory switch – Disables most of the dynos memory, which disables the dyno graph and peak values with their calculations, excluding top speed (useful to reduce lag by quite a bit more)
Gray angle switch – Inverts the x-axis for the dyno graph to make them more relevant and comparable to real life dyno graphs (incase you prefer that)
Yellow switch – On/Off
Yellow button – Reset
Black switches next to the main value units – allows you to change the displayed units
Engine, Rpm, Torque, Horsepower, Engine Dynamometer, Tool
