This performance module upgrades engine management for older Civic and RSX platforms by replacing factory fuel mapping with a calibrated DW400 controller paired with a DW430c returnless interface. Designed for 2001–2006 Honda and Acura applications, the unit optimizes fuel delivery for bolt-on modifications and improved drivability while retaining returnless fuel-system compatibility and direct-fit electrical connections.
Features:
- DeatschWerks DW400 performance module
- Includes DW430c returnless fuel controller
- Direct-fit for 2001–2006 Honda/Acura wiring
- Optimizes fuel delivery for bolt-on modifications
