WIRING AND SETUP WARNING
If your ignition or fuel system is incorrectly configured and the ECU is powered up, damage to the engine or components may occur. To avoid damage remove the main ignition and injection fuses before powering up for the first time. Re-fit fuses when the configuration of the ignition and fuel system is completed and checked in the Elite Software Programmer.
It is good practice to also disconnect when updating firmware within the ECU.
Failure to follow all the warnings and precautions in this manual can lead to damage to engine components and may possibly void your warranty. Incorrect setup of the ECU can also lead to damaged engine components.
Damaged components due to incorrect setup will not be regarded as warranty repairs.
GENERAL INSTALLATION WARNING
Avoid open sparks, flames or operation of electrical devices near flammable substances. Always disconnect the battery cables when doing electrical work on your vehicle.
Do not charge the battery with a 24 Volt truck charger or reverse the polarity of the battery or any charging unit. Do not charge or disconnect the battery with the engine running as this could expose the ECU to an unregulated power supply that could destroy the ECU and other electrical equipment.
All fuel system components and wiring should be mounted away from heat sources, shielded if necessary and well-ventilated. Disconnect the Haltech ECU from the electrical system whenever doing any welding on the vehicle by unplugging the wiring harness connector from the ECU.
After completing the installation, make sure that there are no fuel leaks, and no wiring left un-insulated in case a spark or short-circuit occurs and causes a fire. Also make sure that you follow all proper workshop safety procedures. If you’re working underneath a jacked-up car, always use safety stands!

ELITE SERIES
INTEGRATED HELP MANUAL
A comprehensive instruction manual is available within the Nexus Software Programmer which contains detailed information regarding installation, setup and tuning of your Elite Series of ECU.
To access, start the Haltech Nexus Software Programmer and press the “F1” key on your computer.
(TRIGGER) / ( HOME )
OVERVIEW
The crank and cam position sensors are required so that the ECU has the necessary information available to it to determine engine speed and position at any point in time.
Generally, two sensors are required – a cam position and crank position, however, many cars will have just a cam position sensor that is capable of giving the ECU enough information to run the engine correctly. Vehicles that have a crank position sensor only are not capable of determining the difference between compression stroke and exhaust stroke and therefore are not suitable for sequential fire applications. In this case a cam position sensor may need to be added.
There are generally 2 types of crank/cam sensor signals
- Hall Effect signal (0-5V Digital square wave signal) Generally hall effect sensors have 3 wires – a power supply (could be 5V ,8V or 12V), a ground and a signal out wire.
- Reluctor signal (Analogue style signal) This type of sensor will generally only have two wires, signal Positive (+) and signal negative (- )
AVI ANALOGUE VOLTAGE INPUTS WITH SELECTABLE PULL-UP TO 5V
OVERVIEW
Analogue Voltage Inputs are inputs to the ECU that accept variable voltage signals from OV to +5V such as signals from pressure, temperature and fuel level sensors.
AVI inputs can tolerate a maximum input voltage of 20V. These inputs can also accept switched inputs that change between two different voltage levels. The On Voltage and Off Voltage define what the thresholds are between the on and off states.
The voltage can be viewed as a channel in the Nexus Software Programmer to determine the thresholds for a switched input. Common examples of switched inputs include A/C Request switch and an intercooler spray switch.
AVI-1 and AVI-6 are inputs that are optimally designed to be used with Narrowband 02 sensors due to the AVI having a high input impedance which minimizes the ECU’s load on the OV to 1V signal produced by most Narrowband 02 sensors.
When Narrowband 02 sensors are not used these inputs can be setup and used as any function that is available to the input. AVI’s have a software-selectable 1K pull-up resistor to 5V, which can be enabled or disabled with a check box within the setup page. Pull-up resistors are generally enabled for temperature-related sensors and switched to ground inputs.
SPI
SYNCHRONISED PULSED INPUTS
OVERVIEW
Synchronized Pulsed Inputs are capable of measuring the position, duty cycle, frequency or state of a signal. These inputs are suitable for sensors such as cam position sensors, fuel composition sensors, road speed sensors and flat shift switches. Synchronized Pulsed Inputs are compatible with digital (hall effector optical) and reluctor (analog) based sensors, have a maximum input voltage rating of 25VDC and can measure up to 50KHz Maximum frequency.
KNOCK
KNOCK DETECTION
OVERVIEW
A knock sensor detects engine knock and sends a voltage signal to the ECU. The Elite Series ECU uses the knock sensor signal to modify ignition timing if knocking occurs. Knock detection can be performed by the Elite Series ECU by installing a compatible piezoelectric knock sensor mounted to the engine block.
DPO
DIGITAL PULSED OUTPUTS
OVERVIEW
Digital Pulsed Outputs are capable of producing pulsed waveforms with varying duty and frequency.
DPOs can be used to control various devices such as thermostats, shift lights, bypass air control valves, boost control solenoids etc. When a Digital Pulsed Output is activated by the ECU the output will switch to ground. Solenoid valves and shift lights etc can be run directly from the output, however, high-current devices such as thermo fans and additional fuel pumps must be activated through a relay, this way the DPO is only switching a relay and not a high current draw device.
The Pull-Up Voltage specifies the waveform maximum voltage output ie 0 to 12V, 0 to 8V or 0 to 5V.
The Pull-Up Voltage specific to each DPO is outlined below:
DPO 1 : User definable 0-12V Pull-Up
DPO 2 : Fixed 5V Pull-Up
DPO 3 to 6 : Fixed 12V Pull-Up
OUTPUT: Ground @ 1A Max Current
IGNITION
IGNITION 1 – 8
OVERVIEW
Ignition outputs must be connected directly to an ignition module to control the ignition of the vehicle. Do not connect directly to a coil without an internal or external ignition module as doing this will damage the ECU.
The ECU ignition output produces a signal between 12V and ground to control the ignition module allowing the charging and firing of the coil.
When not used for ignition, these outputs can be used as Digital Pulsed
Outputs (DPO) capable of switching 1A to ground.
WARNING
Connecting the ECU to an ignition module before setting the ignition firing edge correctly may damage the module and coils, therefore it is advised to disconnect the module or the main ignition fuse until the unit has been setup and configured.
INJECTION
INJECTORS 1 – 8
OVERVIEW
All Injectors are wired directly to the ECU’s corresponding cylinder output pins. When an injection event occurs the ECU will ground the output pin opening the injector.
All injectors are wired to a common +12V supply from the injector relay located within the fuse box.
When not used for injection, these outputs can be used as Digital Pulsed Outputs (DPO) capable of switching 1A Max to ground.
DBW
DRIVE-BY-WIRE THROTTLE CONTROL
OVERVIEW
The Elite Series ECU’s can control most OEM electronic throttles. Drive-by- wire throttle control is an advanced feature of the Elite Series ECU’s. It is recommended that a brake switch is wired to an input on your ECU as an additional safety feature.
Please consult the help information contained within the Nexus Software Programmer for extensive information on compatibility, wiring, setup, and calibration.
STEPPER
STEPPER MOTOR CONTROL
OVERVIEW
The Elite Series ECU’s have 4 wires capable of controlling most OEM Stepper Motor type Idle Speed Control Valves (4 & 6 wire) and Oil Metering Pumps found on rotary engines. Please consult the help information contained within the Elite Software Programmer for more information on wiring and setup. Stepper outputs can also be used as Digital Pulsed Outputs (DPO) capable of sinking 1A Max to ground and driving 1A Max to 12V.
MAIN POWER
POWERING UP THE ECU
OVERVIEW
There are two types of harnesses available for each product. Premium Harness,
which includes a pre-terminated fuse and relay box, and the Basic Harness,
which does not.
Please refer to your specific harness wiring diagram for more information. The
main connections are outlined below:
WARNING
To avoid damage to the ignition components and engine, disconnect the main
ignition and injection fuses from the fuse box prior to powering up and
configuring for the first time.
Ensure your engine block is grounded via a ground strap connected directly to
the battery – terminal or chassis
