ARMAX PERFORMANCE ECU (Engine Control Unit)

The ARMAX ECU blends seamlessly with the factory ECU due to its ability to sense engine load from multiple sources such as Engine RPM, Manifold Pressure, Fuel Pressure, Throttle Position and Exhaust Gas Temperature.

From here the ECU very precisely calculates the engine load and accordingly adjusts the parameters to meet the pre-calibrated demand.

The ARMAX ECU delivers a strong yet very smooth power enhancement, as the driver demands more power the ECU delivers more power.

TEMPERATURE CONTROL

Exhaust Gas Temperature (EGT), is the single most important factor to the long-term life of your internal combustion diesel engine.

If EGT values increase to dangerous levels then engine failure is imminent. That is why the ARMAX ECU utilizes a closed loop sensor feedback system to constantly monitor the vehicles exhaust gas temperature allowing for instant response.

When abnormally high EGT values are reported by the EGT sensor, mounted in the vehicles exhaust system, the ECU decreases the amount of fuel injected into the engine. This reduction allows the EGT to return to safe operating levels reducing load on the engine.

Once this has occurred the ECU will then gradually increase the amount of fuel injected, allowing the engine to return to full power in a controlled manor.

Adversely, if the EGT value is too cold (low engine temperatures), the ARMAX ECU progressively adds power as the operating temperature of the vehicle increases.

Another feature of the total EGT protection system is the ARMAX ECU carries out a number of plausibility checks, this system ensures the closed loop exhaust temperature feedback system is always precise in its reporting.

If a check falls outside the allowable tolerance the unit simply reduces the power level and protects the engine.

This feature is unique to the Safari ARMAX ECU providing total peace of mind.

The ARMAX ECU also calculates the engine cooling system temperature, this is important as a large percent of engine wear occurs when the engine is cold. Accordingly, the ARMAX ECU doesn’t apply any additional power whilst the engine is cold i.e. on start up. As the engine warms up the ARMAX ECU progressively increases its influence, once full operating temperature is achieved the unit will perform to its full potential.

MAP SELECTION

The Safari ARMAX Engine Control Unit (ECU) includes an illuminated in-cab adjustable map selection switch. The press of a button changes your vehicles driving characteristics between 5 different modes (maps).

1.COMFORT – Progressive power and torque delivery, great for everyday driving.

2. SPORT – Enhanced throttle response with strong power and torque delivery.

3. TOWING – With an emphasis on low end torque and reduced top end power to protect your vehicle whilst towing extra weight at ease.

4. TRACTION ASSIST – Slow and smooth throttle response whilst maintaining full power and torque to navigate difficult terrain.

5. STANDARD – Vehicle set to standard OEM power and torque output. Allows ECU to be fitted to brand new vehicle for run-in period.

The map selection switch comes with a 500mm long flying lead so the switch can be easily installed in any position conveniently located to the driver.

DRIVETRAIN PROTECTION

OE manufacturers utilize a system on vehicles called torque reduction on gear change. This reduces the torque applied by the engine to the transmission when a gear change occurs. This allows the vehicle to shift gears smoothly but most importantly protect the life of the internal components of the transmission.

The Safari ARMAX ECU is specifically programmed to sense whe

n the gear change is occurring and also reduces the torque to ensure the transmissions performance and service life is totally preserved.

This feature, coupled with the engine protection systems offers a total drivetrain protection solution.

ULTRA FAST MICROPROCESSOR

The Safari ARMAX ECU has the most advanced microprocessor available, parameters are measured and adjusted in micro seconds. Countless hours of development were implemented to ensure the Safari ARMAX microprocessor was robust, versatile but most importantly could process information at extremely high speeds.

THROTTLE MANAGEMENT

The Safari ARMAX Performance ECU incorporates the ability to adjust the sensitivity of the vehicles throttle pedal, this greatly improves throttle response and can be custom tuned to your individual needs.

AUXILLARY INPUTS/OUTPUTS

The Safari ARMAX Performance ECU incorporates the ability to adjust the sensitivity of the vehicles throttle pedal, this greatly improves throttle response and can be custom tuned to your individual needs.

ETHERNET COMMUNICATIONS

The Safari ARMAX Engine Control Unit (ECU) has high speed reliable and extremely robust Ethernet communication between the ECU and your PC. The benefits are precise real-time data analysis and instantaneous download of updates as well as different engine maps.

Ethernet connectivity is also used to provide data logging, this enables engine analysis to be viewed live via the M1 tune software whilst connected to a PC or be down loaded and viewed remotely.

This gives Safari the ability to perform engine diagnostics and troubleshooting.

AUSTRALIAN MADE

Safari’s excellent reputation in Australia for manufacturing high quality 4×4 components is unchanged with the Safari ARMAX Performance ECU. All components are proudly made and assembled in Australia to ensure the highest quality is achieved as well as being rigorously tried and tested for countless hours in some of Australia’s harshest environments.

SERVICE PLUG

Included in every Safari ARMAX application kit is a black anodized 6061 billet aluminium service plug. This enables the Engine Control Unit to be bypassed for the purpose of diagnostics or to allow the vehicle to be returned to standard in the event the ‘Standard’ map selection has been used for a user defined map. The connector can be fitted or removed in a matter of seconds.

CAN COMMUNICATIONS

Controller Area Network (CAN Bus) allows microcontrollers to communicate. The Safari ARMAX ECU incorporates a CAN bus which allows for auxiliary device connection i.e. digital display or integrate further with on-board OE controllers.

WARRANTY

Adding to your peace of mind is Safari 4×4 Engineering’s warranty program, offering an unlimited kilometre 3-year warranty on all components. This is also backed up by an industry leading vehicle drivetrain warranty.
