The Grullo has had a pretty big overhaul!

This update includes:

ENGINES:

-Added four new 455ci RY45 engine options with approximately 800, 860, 930 and 996 HP.

-Completely rebuilt the engine torque curves using real-world RY45, D3 and similar Ford race-engine dyno data.

-Improved low and mid-range torque so the engines behave more realistically for their displacement.

-Each engine now has its own power delivery, RPM range and limiter instead of being the same curve with different peak numbers.

TRANSMISSIONS AND DRIVETRAIN:

-Reworked the existing Fortin FRST5 transmission with proper dog-ring engagement simulation.

-Added ignition-cut upshifts and automatic throttle blipping on downshifts.

-Badly timed downshifts can now refuse engagement or damage the dog rings.

-Added dog-ring wear and gear failure from repeated bad shifts.

-Added a proper input-shaft brake/transbrake system for launching the truck.

-Prevented first gear from engaging while the transmission input is spinning too quickly.

-Reworked drivetrain losses across the transmissions, drop gear and transfer cases for more realistic power delivery.

DIFFERENTIALS AND 4WD:

-Replaced the fake Detroit-style LSD with a custom automatic locker that locks under power while allowing the outside wheel to overrun in corners.

-Added Detroit locker support to the rear axle.

-Renamed the welded front differential to Front Spool.

-Replaced the old sprag-equipped Atlas setup with a Fortin FRTC2 2-Speed Transfer Case.

-Added selectable high- and low-range drop-gear ratios to the Fortin transfer case.

-Completely reworked the front-output sprag system.

-Unlocked mode now behaves like a proper one-way sprag, driving the front axle while still allowing it to overrun.

LIVE VALVE SUSPENSION:

-Added a complete FOX RAD-inspired automatic Live Valve system for the bypass shocks.

-Uses 14 inputs overall: 6 vehicle-level sensors/inputs, plus 2 individual inputs per shock, allowing the system to react accordingly at every corner and bump.

-The controller has 4 adjustable control equations.

-It automatically manages the compression and rebound bypass circuits in real time, with adjustable maximum authority for each bypass tube.

-Includes automatic jump-landing protection, detects a big jump and closes all bypass valves before a hard landing.

MOTEC C127 DASH:

-Added a completely custom MoTeC C127-style dash interface.

-Added a second round C127 layout with a large central gear indicator and circular tachometer.

-Added live RPM sweeps, engine-specific rev-limit areas and improved tachometer scaling.

-Added sequential shift lights with paired lighting stages and a flashing warning before the limiter.

-Added working coolant temperature, oil temperature, headlight, high-beam, check-engine and low-fuel warning lights.

GENERAL:

-Numerous Lua and JBeam fixes.

-Various tuning, naming and Parts Selector improvements.

-Small performance and UI improvements.

The update is available now for all eligible members.
