Getting Started

Everything you need to go from a cold engine to a running, tunable one.

What Engone is

Engone is a modular, realistic engine and ECU simulator. You assemble an engine from real components — block, crank, pistons, head, cam, intake, exhaust, optional turbo — and the simulation derives its displacement, compression ratio, redline, and breathing from those parts. A real-style ECU then runs the engine: estimating air mass, metering fuel, timing the spark, and managing idle, boost, and limits. It models both petrol (spark ignition) and diesel (compression ignition), with naturally aspirated and forced-induction setups, plus a built-in dyno.

Why it's organized this way

The wiki mirrors how the ECU actually works, split into six categories:

• Fuel — how much fuel, and when.
• Ignition — when the spark fires.
• Sensors — the inputs the ECU reads.
• Engine Setup — the hardware you build.
• Outputs — what the ECU controls.
• Reference — terms, troubleshooting, modding.
