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

Terminated harness suits LSx engines with DBW, and incorporates PDM functionality.

• EV6 primary injector plugs.
• Plug and play with the OEM Ignition sub-harness on the engine. (Required)
