Tire Pressure Control

Central Tire Inflation System (CTIS) controller that allows dynamic adjustment of tire pressures while driving. Used on military and off-road vehicles to optimize traction for different terrain types (lower pressure for sand/mud, higher for road).

Two-Step Launch Control

Implements a two-step rev limiter for drag racing launches. Holds engine RPM at a configurable launch RPM (lower than redline) while the driver holds the brake, then releases to full RPM when launched. Builds boost pressure on turbocharged vehicles.
