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 we call a VCU (Vehicle Control Unit).
Features
- 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), eg for electronic throttle
- 11 x 0-5V analog inputs with redundancy for electronic throttle and switchable 5V 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 0-5V 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
Harness Overview
Ideal for dedicated race cars, engine swaps and custom wiring jobs. The Universal Wire-in Harness has a set of VCU connectors at one end and unterminated wires at the other. All the wires at the unterminated end are colour coded and clearly labelled. 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!
Features
- Colour coded and labelled wires that match the detailed wiring diagram for a confusion free construction process.
- The wiring diagram is accompanied by the full VCU manual and Software located on the USB key provided with the VCU, or downloadable from the Haltech Website.
