Plug-in Perfection: Platinum PRO ECU for Honda DC5/RSX (05-06)
The Haltech Platinum PRO Plug-in ECU is the definitive engine management solution for the facelift Honda Integra DC5 / Acura RSX (2005-2006). Designed for non-Drive-By-Wire, manual transmission models, this ECU plugs directly into the factory wiring harness, replacing the OEM computer entirely. It is pre-configured to control the K20Z1’s i-VTEC system, including variable cam timing (VTC) and VTEC switchover, ensuring optimal performance.
Feature-Rich & Flex-Ready
Designed for serious performance, the Platinum PRO supports real-time tuning, high-resolution data logging, and closed-loop boost control. It features an internal MAP sensor (rated to 22psi) for simplified installation but can also use external MAP sensors for higher boost applications. This unit retains full control over the factory instrument cluster and AC system. It requires an external CAN I/O 12 Expander Box to accept a Flex Fuel sensor input, enabling E85 tuning capabilities.
