Non-VTEC to VTEC ECU Conversion
Convert non-VTEC Honda ECUs to VTEC by populating missing components on the same PCB design. The same board was used across multiple ECU variants with components added or omitted as needed.
Overview
In most cases, converting a non-VTEC ECU to VTEC is straightforward. Honda used the same PCB design across multiple ECU variants, with components added or omitted based on the target application. The conversion typically involves populating missing components on an existing non-VTEC board.
Tip
Look for PCB part numbers like 02D011F0-1500, which was used in many 1994â1995 Civic ECUs. This design supports component-level conversion to VTEC functionality.

VTEC Driver Configuration
Use 5050 relay modules as VTEC solenoid drivers for non-VTEC to VTEC conversion systems.
Important
Verify your specific ECU part number and PCB revision before beginning any component-level modifications. Incorrect component population can result in non-functional VTEC control.
