Description
This is an app for tuning the ECU in BeamNG. It works on virtually any car, with any engine or turbocharger. It’s designed like a real chip-tuning bench, but its main purpose is for educational purposes.
Tuning is performed using real maps. Color-coded fuel, ignition, boost, and lambda maps are available. You can select groups of cells and modify them by addition, subtraction, scaling by percentage, filling, smoothing, interpolation, copying, and pasting. Display modes for the base map and difference map are available; the active cell shows the engine’s current position on the map, and a 3D view of the map is also available.
The real-time page displays all engine operating parameters: lambda, knock, injector duty cycle, fuel pressure, intake temperature, and engine status, with alerts for deviations.
The built-in dynamometer allows you to evaluate tuning results. After taking a measurement, you receive power and torque curves, and the first measurement is saved as a baseline for comparison with subsequent ones.
The “Training / Lessons” button launches a step-by-step guide. The car is configured for the lesson, and a sequence of actions is displayed with an explanation of each step.
There are 8 lessons available, ranging from beginner to advanced levels:
- Reading instrument panel readings
- Correcting a rich fuel mixture
- Power and knock
- Power tuning on a dynamometer
- Additional methods for increasing power (fuel mixture composition, valve timing, boost)
- Setting up a two-stage launch limiter
- Tuning boost pressure on a turbocharged vehicle
- Creating a safe tune with a turbocharger
In version 3.1.4:
A number of bugs have been fixed. In particular, an issue with the tutorial lessons that would advance to the next page too quickly, leaving no time to read, has been fixed.
The “pops and bangs” sounds are now louder.
Dark Mode.
Rotary engines: They are now tuned to account for the specific characteristics of rotary engines. The absence of valves, correct injection timings, and the actual displacement of Mazda engines (13B, 20B, 26B) have been accounted for, ensuring that fuel and injector parameters match those of real rotary engine ECUs. The OEM turbo kit (OE Turbo kit) is now also compatible with rotary engines.
Idle mode with a “rotary” sound (Rotational idle): available in either simple or manual mode. Automatic mode works with two sliders, just as before. Manual mode allows you to configure the idle yourself by modifying the corresponding cells in the fuel and ignition tables (as in older versions). You can also set higher target idle RPMs (up to 3,000 RPM) for engines that run at high idle speeds.
Synchronization of “backfires” with the car’s exhaust sound: The stock “backfire” sounds are now played simultaneously with the natural pops in the car’s exhaust system—when lifting off the throttle, shifting gears, and when the rev limiter engages. You can choose to play both sounds together or use only the stock samples (replacing the car’s actual sound with them). This feature works when the setting is enabled and can be disabled on the “Pops & Bangs” page.
Staged Injection: For engines equipped with more than one injector per cylinder or rotor (for example, the rotary engines in the RX-7 and RX-8). The primary injectors operate independently under low load, while the secondary injectors engage as the load increases—just as in real-world staged injection systems. The activation points and output of the secondary injectors are configured on the new “Staged Injection” page. If the secondary injector output is set incorrectly, the air-fuel ratio will change precisely when they activate—just like in a real car. Also added: default axis settings. Save your preferred axes for fuel and ignition tables once, and they’ll be used for all new cars.
Custom Blow-Off Valve (BOV) Sounds: Select a new blow-off valve sound and adjust its volume on the “Boost Control” page.
