Elite 550 ECU + Plug and Pin Set (HT-150401)

Full standalone control of fuel, ignition and boost, at the entry price.

The Haltech Elite 550 ECU + Plug and Pin Set is the Elite 550 ECU with the matching plug and pin set. The Elite 550 is Haltech's entry-level single-connector Elite: full control of fuel, ignition and boost for a basic four-cylinder, V8 or two-rotor build, with flex fuel and on-board logging included.

The plug and pin set gives you the ECU-side connectors and terminals to build your own loom from scratch, to whatever length, routing and wire spec the car needs. It is tuned in Haltech's NSP software, the same package used by the Nexus range.
