In this paper, we present an enhanced massively multi-agent system based on the previous MMAS for discovering the unique dynamics of HIV infection [1]. The enhanced MMAS keeps the spacial characteristics of cellular automata (CA), and employs mathematical equations within sites. Furthermore, new features are incorporated into the model, such as the sequence representation of HIV genome, immune memory and agent remote diffusion among sites. The enhanced model is closer to the reality and the simulation captures two extreme time scales in the typical three stages dynamics of HIV infection, which make the model more convincing. The simulation also reveals two phase-transitions in the dynamics of the size of immune memory, and indicates that the high mutation rate of HIV is the fatal factor with which HIV destroys the immune system eventually. The enhanced MMAS provides a good tool to study HIV drug therapy for its characterizing the process of HIV infection.
