GC Tuning — Quick Search Preview
PROFESSIONAL VEHICLE & ECU REFERENCE

GC Tuning ECU / TCU Finder

Search UK vehicles and possible ECU / TCU codes, with a growing set of sourced physical ECU-location guides. All results are potential matches; ECU and mounting location must be confirmed on the vehicle.

QUICK VEHICLE SEARCH
Year-filtered sourced entries refer to listed model generations, not verified ECU fitment in every subsequent year. Confirm via ECU ID.
Sourced modern / model-year example Imported catalogue — year unverified Legacy provisional reference
More possible matches — year not verified

The supplied list does not contain model years. These matches may or may not apply to your selected year.

📍 ECU location guides — searchable workshop directory

Locations below are model/generation/engine-specific starting points , not guaranteed locations for all trims. Verify against workshop documentation and the actual vehicle before removing anything. Where a catalogue row lacks a chassis code, use this directory to check the reference separately.

Browse ECU / TCU models

Browse the uploaded control unit directory and click any code to see its associated vehicles.

Compatibility caution: Most imported records have no vehicle-year field; some newer examples are individually sourced and model-year tagged. Duplicate or variant entries may still exist. Do not assume that every year, engine code, ECU part number or programming method matches. Verify the fitted control unit using its label or diagnostic identification before quoting or flashing.
