Haltech Nexus T2 ECU - HT-211000

The Haltech Nexus T2 is a compact, standalone ECU and the successor to the Elite 750. It's Haltech's entry point into the Nexus range, built for street performance builds and EFI conversions on engines up to 6 cylinders or 3 rotors, naturally aspirated or boosted. You get full control of fuel, ignition and boost in a sealed, waterproof case with a single connector, and the ECU comes fully enabled with no extra charges to unlock advanced features.
