Haltech Nexus R3 VCU with Universal Wire-In Harness Kits

Haltech Nexus R3 with universal wire-in harness kits are ideal for dedicated race cars, engine swaps and custom wiring jobs. The harness has a set of VCU connectors at one end and unterminated wires at the other. All the wires at the unterminated end are color-coded and clearly labeled. Connect your Haltech VCU to the terminated end and follow your wiring diagram for all the engine connections. Load your base map and you're ready to go!

* Color-coded and labeled wires that match the detailed wiring diagram for a confusion free construction process.
* The wiring diagram is accompanied by the full ECU manual and software located on the USB key provided with the VCU, or downloadable from the Haltech website.

VCU OVERVIEW:

* Nexus R3 combines the functionality of a power distribution module, a data logger, a wideband controller, and a state-of-the art engine management system in one powerful device Haltech calls a VCU (Vehicle Control Unit)
* 4 x 25A (continuous) push-pull PWM capable (5 kHz) outputs (for power to injectors / coils, transbrake, thermofan, fuel pump)
* 8 x peak/hold injector drivers (can be used as low side drive outputs)
* 8 x low current ignition outputs (can be used as low side drive outputs)
* 6 x low side drive outputs, PWM capable (DPOs)
* 6 x push-pull /H-bridge outputs (8A, PWM capable), e.g. for electronic throttle
* 11 x 0-5 V analog inputs with redundancy for electronic throttle and switchable 5 V pullup
* Trigger and home inputs with differential inputs, adjustable thresholds and glitch filters
* 6 x synchronous pulsed inputs, zero crossing or adjustable thresholds - cam sensor inputs, frequency inputs or 0-5 V analog inputs
* 1 x on-board wideband controller, supporting NTK and LSU4.9
* 1 x on-board 4 bar MAP sensor
* 2 x CAN ports with switchable termination

* Suits: Engines with up to 8 cylinders or up to 4 rotors. Racing applications where advanced race features, data logging and power management control are required.
* Includes: Nexus R3 VCU, SurLok connectors (red and black), WiFi antenna, mounting bolts, USB-C cable, USB-C dust cap, USB drive with NSP software. Nexus R3 universal wire-in engine harness.
