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.
VCU OVERVIEW
Nexus R5 is Haltech’s flagship product combining the functionality of a power distribution module, a data logger, a dual channel wideband controller and a state-of-the art engine management system in one powerful device we call 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)
12 x 8A (continuous) high side outputs (low speed PWM, 200 Hz) outputs (power to sensors, NOS solenoids, etc)
18 x peak/hold injector drivers (can be used as low side drive outputs)
12 x low current ignition outputs (can be used as low side drive outputs)
8 x low side drive outputs, PWM capable (DPOs)
4 x push-pull / h-bridge outputs (8A, PWM capable), eg for electronic throttle
23 x 0-5V analog inputs with redunancy for electronic throttle and switchable 5V pullup
Trigger and home inputs with differential inputs, adjustable thresholds and glitch filters
10 x synchronous pulsed inputs, zero crossing or adjustable thresholds – cam sensor inputs, frequency inputs or 0-5V analog inputs
2 x onboard wideband controllers, supporting NTK and LSU4.9
3 x CAN ports with switchable termination
