Options & Units¶
Units, camera, slider speeds, warm-up speed, wear rate, volume and graphics — everything you can change about how the game behaves and displays.
What it is¶
The OPTIONS page has four tabs: GAMEPLAY, CONTROLS, AUDIO and GRAPHICS. Settings are saved
between sessions.
Units
Numbers on this wiki use metric units (kPa, °C, Nm, kW). In the game you can change every display under OPTIONS → GAMEPLAY → UNITS. Your tunes are unit-independent.
GAMEPLAY tab¶
UNITS. UNIT SYSTEM is Metric, Imperial or Custom. Then each quantity separately:
| Setting | Choices |
|---|---|
MANIFOLD PRESSURE |
kPa / bar(a) / psia |
BOOST / GAUGE PRESSURE (the gauge-pressure display) |
bar / psi / kPa |
TEMPERATURE |
°C / °F |
TORQUE |
Nm / lb·ft |
POWER |
kW / hp / PS |
MIXTURE |
λ / AFR |
Tables, curves, gauges and the Setup stats all follow your units, and saved tunes are identical in any unit.
GENERAL. CAMERA SENSITIVITY, CURSOR SPEED (UI), INVERT Y AXIS, SHOW TOOLTIPS, and
UI SCALE (0.5–2).
SLIDER RESPONSE. THROTTLE CHANGE RATE and LOAD CHANGE RATE, each 25–200 %/s, default 50. They
set how fast W / S and the dyno's Q / A change their values.
ENGINE WARM-UP.
WARM-UP SPEED— 1×–10×, with "1.0x (realistic)" as the default. It scales heating and cooling, so the equilibrium temperatures don't change.ENGINE WEAR RATE— OFF, 1×, 10× or 100× (logarithmic).WARM ENGINE NOW→SET WORKING TEMP— puts all temperatures at operating values instantly.
CONTROLS tab¶
A read-only key list. See Controls.
AUDIO tab¶
MASTER, ENGINE, DYNO and STARTER volume.
GRAPHICS tab¶
FULLSCREEN, VSYNC, QUALITY LEVEL, SHADOW QUALITY and ANTI-ALIASING.
Why it matters¶
Several of these change how you tune, not just how the game looks: MIXTURE switches every λ display
and the lambda table between λ and AFR; WARM-UP SPEED and SET WORKING TEMP skip the 15-minute warm-up;
ENGINE WEAR RATE decides whether mistakes cost you parts (see Damage & Wear).
How to tune it¶
Pick units you think in, and leave the rest alone until you have a reason to change it.
Rule of thumb
Turn wear OFF while you learn, and use SET WORKING TEMP to skip the warm-up. Switch wear back on
when you want mistakes to cost something.
