Many builders start with ECU Master because it’s affordable and gets the job done — a smart choice when budgets are tight. But as your build evolves, you may want more precision, refined control, and a larger pool of advanced tuners.
That’s where our custom adapter comes in. It allows you to upgrade your existing ECU Master setup to a Link ECU, unlocking full tuning control, advanced features, and a wider network of experienced tuners — without ripping out or repining your existing harness.



Why Upgrade?
Complete control and precision: Link ECUs provide a higher level of tuning accuracy and complete flexibility.
Wider Tuner Support: Link’s platform is widely adopted, giving you more options for professional calibration and diagnostics.
Plug-and-play simplicity: Reuse your ECU Master harness — no rewiring headaches.
Proven Design: Built and tested in-house on our own car before release.
Features
Direct pin mapping: Every wire matched to the correct Link ECU pin
Durable connectors built for engine bay conditions
Reuse your existing harness — save time and money
Custom configurations available upon request
Installation Notes
Includes adapter harness and documentation
Verify your harness version and Link ECU model for compatibility
Adapter handles wiring only — tuning and setup performed in Link ECU software
Requirements
To ensure a smooth transition and proper base calibration, we’ll need a few details from your current setup:
Existing ECU Master I/O configuration: Complete input/output list or pinout.
Current ECU Master map file: Used to reference your existing sensor scaling, trigger setup, and base tune data.
Providing this information allows us to build a base map for your new Link ECU that closely reflects your current running configuration — minimizing setup time and keeping your engine safe during the switch.
