Unlock Your Classic Honda: Nexus S2 Plug ‘n’ Play Adaptor Kit (OBD-I)
Modernize your OBD-I Honda Civic, Integra, or Prelude with the Haltech Nexus S2 Plug ‘n’ Play Adaptor Kit. This package replaces the aging factory ECU with the cutting-edge Nexus S2 VCU (Vehicle Control Unit), bringing 21st-century engine management technology to the golden era of Honda tuning. The kit includes the Nexus S2 and a high-quality adaptor harness that plugs directly into the factory OBD-I wiring connectors, making installation straightforward and reversible.
Advanced Features for B/D/H-Series
With the Nexus S2, you gain access to features previously unavailable on these platforms, such as Drive-By-Wire throttle control (requires retrofit), advanced knock control, and high-speed data logging over Wi-Fi. The adaptor harness supports all factory sensors and actuators while providing an auxiliary I/O breakout for adding modern sensors like wideband O2, fuel pressure, and flex-fuel content. Included is a fast-response air temperature sensor to convert from the stock system to Speed Density tuning, removing intake restrictions.
