Haltech Nexus R5 VCU + Universal V8 Terminated Harness

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

Onboard data logging - Up to 300 channels of logging at sample rates up to 1ms (1kHz) with 512MB of internal memory

Terminated Engine Harness connects directly to the Nexus R5 VCU and supports most popular big block and small block V8 engines from GM, Ford and Chrysler.
Harness requires Injection, Ignition and alternator Sub Harnesses - Sold seperately.
