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 Terminated harness suits LSx engines without DBW, incorporates PDM functionality. EV1 primary injector plugs. Plug and play with the OEM Ignition sub-harness on the engine. (Required) Includes 1 x HT-186206 Terminated Harness 1 x Pack of DTM/DT connector and pin set to terminate to sensors, solenoids and other devices 2 x DTP-2 connectors with pre-crimped 12AWG wires to use for fuel pump and thermofan 1 x DT-8 connector with pre-crimped 18AWG wires 1 x 2 pin Bosch alternator adaptor harness 1 x 2 pin Yazaki alternator adaptor harness 1 x 4 pin Delco alternator adapter harness VCU FEATURES Controlled via NSP (Nexus Software Programmer) Long Term Learning Stepper Motor Control 4D Closed Loop Boost Control Closed Loop CO2 Control Rotational Idle Launch Control Traction Control Anti-Lag Dual Knock Control Trans Brake Control Race Timer Multi Stage Fuel Injection Multi-level Engine Protection 6 Stage Nitrous Control 4-sensor variable cam control Intake Air Bleed Control Flat Shift Control Shock Travel & Ride Height Control Advanced Torque Management On-board Wi-Fi AUTOMATIC TRANSMISSION CONTROL Ford AODE/4R70W GM 4L60E GM 4L80E Toyota A340E Lenco Liberty 8 x Primary injectors (EV1) Breakout plug for 8 x Secondary injectors 2 x outputs available for Tertiary injection Single / Dual boost solenoid control Dual wideband sensor control (R5 onboard wideband controller) Flex fuel sensor connection Direct fuel pump control (using 25A-HCO) Direct thermofan control (using 25A-HCO) In-cabin breakout connector for spare inputs and outputs Engine bay breakout connector for spare inputs and outputs (eg transmission control) Breakout connector for PDM outputs (eg Headlights, indicators, wipers, etc) Haltech CAN Bus support (DTM-4)
