Tuning & fitment support

Buying the ECU is the start, not the end. We can talk you through which harness, sensors and accessories your combination actually needs, and point you toward tuners who know the platform.

Over 20 years of hands-on trade experience sits behind that advice — we build and run these cars ourselves.

Not sure which ECU or harness you need?

Haltech's range spans wire-in ECUs, plug-in ECUs, terminated harnesses and plug-and-play kits. The right choice depends on your engine, throttle type (cable or drive-by-wire) and injector connectors.

Send us your engine, model year and current setup and we'll confirm the correct part number before you buy.
