ONLY SUITS PXII & PX III 3.2L 5Cyl Models

The Safari ARMAX 'X Series' Engine Control Unit (ECU) is designed to work harmoniously with your vehicles OE Engine Control Unit resulting in more power, more torque, better throttle response, less fuel consumption and less turbo lag. This is all backed up by Safari’s sophisticated engine protection systems which are constantly live monitoring your vehicle for total drivetrain safety and ultimate reliability. The ARMAX ECU has 5 pre-calibrated maps for all user conditions but can be altered to suit specific applications. The plug and play wiring harness makes installation quick and easy and vehicle specific mounting bracketry complements the installation. The Safari ARMAX 'X Series' ECU is the total package, no upgrades required, no additional units needed. It is a total system solution specifically designed for your 4x4 vehicle.

The 'X Series' ARMAX ECU increases the open duration and the injection timing point of the fuel injector, allowing more diesel fuel to enter the combustion chamber. Due to the increase in fuel, the boost pressure the engine receives from the turbocharger is increased, optimizing the air fuel ratio. The result is increased engine power, torque, and better throttle response.

In some applications, the fuel system pressure is increased at specific engine RPM points and load demands to ensure accurate fuel delivery to the injector. 

This approach ensures the service life of the mechanical components in the fuel system are not influenced. Another Standard feature of the ARMAX ECU is the ability to change the throttle sensitivity, this feature can be tailored to individual driver requirements.

The 'X Series' 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.

IP68 RATED

The Safari ARMAX ECU enclosure proudly earned an IP68 (Ingress Protection) rating meaning it is protected from dust, dirt and sand ingress and can be continuously submersed in water beyond 1m.

The Safari ARMAX ECU received such an impressive IP (Ingress Protection) rating with the use of several key features:

• The enclosure has a billet aluminium base which also acts as the main heatsink for the printed circuit board (PCB).
• An ABS plastic glass reinforced housing which offers excellent impact protection.
• A unique and cleverly designed perimeter sealing system.
• An automotive vent which continuously balances the internal pressure of the enclosure as well as removing any internal condensation.
• Resin filled enclosure to protect the PCB against vibration and aid in thermal shock protection.

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.

CALIBRATION FILES

Safari 4x4 Engineering have an extensive library of calibration files (tuning maps) to suit standard vehicles as well as multiple combinations of popular vehicle modifications. These include items such as Snorkels, Intercoolers and Exhaust systems. It is critical that the correct calibration file for your vehicle is installed to ensure the maximum power level is achieved reliably. These are available for download by an approved Safari ARMAX dealer, files can be changed in a matter of seconds allowing for future modifications to your vehicle.

WIRING HARNESS

Each ARMAX ECU application has a vehicle specific wiring harness to ensure a precise fit which is tailored to each vehicle, it is necessary to route the harness through the vehicle in a specific way, so that the harness is not subject to abnormal vibration, heat, movement and interference. This is vital to ensure the wiring loom lasts the life of the vehicle.

Every connector fitted to the wiring harness is of the highest quality, fully sealed and waterproof, there are no exceptions. Safari uses gold plated terminals at each connection point on the harness.

The internal wires have a dual layer of external protection the same as high quality OE wiring harnesses, the harness breakout points are clearly labelled.

The Safari ARMAX wiring harness is a true “Plug and Play” solution that requires no cutting or soldering into the vehicles original wiring harness, it can be removed, and the vehicle can be returned to its original form without any trace.

MOUNTING BRACKETRY

The Safari ARMAX ECU mounting bracketry which supports the unit is laser cut and folded 3mm plain carbon steel, all brackets are then zinc plated and powder coated. This dual layer offers superior corrosion resistance with great aesthetic appeal. All mounting hardware is high grade stainless steel and utilizes existing factory mounting points.

All components in the design phase were CAD modelled to ensure a perfect fit first time but most importantly analyzed to ensure they would survive the life of the vehicle as well as fitting with commonly used aftermarket accessories such as secondary fuel filters, engine catch cans, auxiliary batteries and air compressors.

M1 TECHNOLOGY

The Safari ARMAX Engine Control Unit (ECU) is powered by M1 technology.

M1 technology is comprised of a suite of tools for developing automotive control systems, with a focus on engine control. It includes features such as a purpose built tuning solution in which Safari has included the most vital engine tuning parameters, data logging and PC communications as well as M1 specific hardware such as the Safari ARMAX PCB (Printed Circuit Board).

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 when 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.
