Beta Realistic Engine 1.0.0

Realistic Engine 1.0.0
Realistic Engine adds a live engine dashboard, diagnostic tools, ECU tuning, and dynamic failures to BeamNG.drive. Try starting a diesel on a freezing morning, track down a misfire under load, or compare two dyno pulls after changing your fuel and timing maps.

Drive and cold starts
Monitor RPM, boost, battery voltage, oil and coolant temperatures, and engine mileage from a draggable HUD. Click a gauge to see its last 60 seconds of data, or pin your most-used gauges in compact mode.

Starting behavior responds to engine temperature, battery condition, and starter load. Voltage drops during sustained cranking, and a weak battery can leave you with a starter click. On diesels, glow plug preheating helps cold starts. A parked battery charger and block heater let you prepare the car before trying again. Gentle driving is fine during warm-up, while pushing the revs too high on a cold engine can build wear and lead to symptoms.

Engine inspection and diagnostics
The animated cutaway follows the fitted engine’s cylinder layout and RPM. Watch the pistons wind down after shutdown and inspect individual cylinders for misfires and condition. A manual cylinder count is available for engines that provide incomplete layout data.

Check active and stored diagnostic codes, review estimated power loss, and run compression, cylinder balance, and cooling pressure tests. The HUD also reports supported damage from BeamNG’s own engine simulation. Mechanical faults can produce audible symptoms such as RPM- and load-dependent knock or valve ticking.

Dynamic failures and mileage
Enable automatic failures to let supported vehicles develop faults based on their age profile, mileage, condition, and how you drive. Percentage-based failure rolls have a separate toggle. You can edit the odometer in miles or kilometers, and the saved mileage survives a vehicle reset.

Use the Faults tab to trigger specific problems on demand, including weak batteries, misfires, valve ticking, head gasket leaks, and turbo wear on compatible engines. You can also change the map’s ambient temperature or set block and oil temperatures separately for testing. On supported diesels, oil ingestion can sustain a runaway after the ignition is switched off. Use the emergency air shutoff to stop combustion.

Repair Mod Faults clears simulated faults. Reset the vehicle to clear damage applied through BeamNG’s native engine system.

ECU and Redneck Tuning
Edit 3×3 or 5×5 fuel and ignition maps, adjust target lambda and spark timing, and watch how the engine responds across RPM and load. Use adaptive fuel trims or take manual control. Three calibration slots let you switch between setups, while live AFR, lambda, and ECU protection readouts help you see what changed.

The Redneck Tuning tab lets you turn up the fuel screw, eyeball the timing, zip-tie the boost controller, fit a junkyard nitrous bottle, or cover the radiator with cardboard. The consequences depend on how you use the car. A tune that feels fine on a short pull can start knocking, overheating, or losing power after repeated hard runs.

Test & Tune
Record and overlay two on-road pulls to compare estimated power, torque, boost, and lambda across the same RPM range. Run both pulls in the same gear for a cleaner comparison. You can also time 0–100 km/h, 80–120 km/h, and quarter-mile runs and keep your personal bests.

Installation and controls

1. Install through the Repository, or put the ZIP in your BeamNG user folder’s mods directory and leave it zipped.
2. If upgrading from a beta, remove the older archive and restart BeamNG.
3. Add Realistic Engine from UI Apps and drag its header to position it.
   • Alt + Shift + E switches between full and compact views.
   • Alt + Shift + H hides or shows the HUD.
   • Hold BeamNG’s default V binding to crank, or use the HUD starter controls.

Compatibility
Tested with both vanilla and modded combustion vehicles. Feature availability depends on what the fitted engine exposes. Automatic age-based failures use matched vanilla vehicle profiles. Electrical health, AFR, per-cylinder wear, and virtual dyno figures are modeled estimates.
