Create aggressive exhaust crackle and pop effects during overrun and gear changes. Customizable settings for intensity and duration to achieve desired acoustic characteristics.
4. HARDCUT LIMITER Vmax
Remove or adjust vehicle speed limiters (Vmax) for increased top-speed capabilities. Essential for track use and performance tuning where factory speed restrictions limit potential.
5. HotStartr Software
Improve cold-start characteristics and reduce warm-up time. Optimize fuel delivery and ignition timing during cold starts for better drivability and reduced emissions during warm-up phases.
6. QLaunchr Software
Launch control system for improved acceleration from standing starts. Adjustable RPM launch limits and traction control integration for optimal launch performance.
