Learn how the Sports ROM in Gran Turismo 3: A-Spec alters engine management for increased power by adjusting sparking period and air/fuel ratio.

The Sports ROM is the most elementary type of tuning available in Gran Turismo 3: A-Spec. It directly alters the engine management system. This modification increases power by adjusting two key aspects of the engine: the sparking period and the air/fuel ratio.

For vehicles equipped with a turbocharger, installing a sports ROM, along with exchanging the air cleaner and exhaust, can achieve a complete tune-up that is suitable for beginners.

Tips
  • Consider installing a Sports ROM as a first step in engine tuning for increased power.
  • For turbo-charged vehicles, combine the Sports ROM with an upgraded air cleaner and exhaust for a comprehensive beginner tune-up.
