Isuzu D-Max ECU Remapping

As Isuzu specialists, we possess an in-depth understanding of every aspect of your vehicle. This is primarily because our workshop handles dozens of Isuzu vehicles for repair every month. Our extensive exposure to Isuzu vehicles gives us a thorough knowledge of their mechanics, electronics, and various components. This expertise enables us to perform tuning and effectively diagnose and address any potential problems arising during the process.

A skilled tuner possesses the following:

• Extensive experience with Common Rail diesel engines.
• A wide range of top-quality tools, including up-to-date software and hardware.
• A state-of-the-art facility for testing, diagnosing, and repairing vehicles.
• A genuine passion for their work.

At Locked in Garage, we specialise in custom-tuning individual ECUs. We conduct Dyno tests before and after tuning to ensure the desired improvements. Our workshop is fully equipped, allowing us to handle all aspects of car servicing “in house,” ensuring comprehensive and efficient service.

Facts:

• In the last decade, almost all diesel cars sold in Australia, including the Isuzu D-MAX, have reduced their performance from the factory.
• The original setup of the Engine Control Unit (ECU) intentionally reduces the torque and power output of the engine by around 15% to 25%. 
• Torque is especially important for diesel engines, providing significant pulling and towing force at low RPMs. In contrast, petrol engines operate differently, delivering more pulling and towing force at higher RPMs, where the power output is maximised. This is due to the difference in torque characteristics between diesel and petrol engines.
• Additionally, engines consume more fuel at higher RPMs. As a result, diesel engines tend to have lower overall fuel consumption than petrol engines, as they are optimised to operate efficiently at lower RPMs.

Safety:

• You might have noticed that your ISUZU D-MAX becomes noticeably slower when the Air Conditioning (AirCon) is turned on. This happens because the AirCon system requires power to operate, and that power comes from the engine.
• Many ISUZU drivers feel frustrated while driving with the AirCon on, as simple maneuvers like overtaking can become challenging. It’s natural to react by pressing the throttle fully when you feel your ISUZU is not performing as expected.
• The issue arises because a diesel engine is designed to provide strong pulling and towing force in the middle RPM ranges (around 2000-4000 RPM). Even with the throttle fully engaged, the car may struggle to complete an overtake on a gently sloping road with a medium load onboard.
• This situation can lead to unsafe driving conditions and increased fuel consumption.
• Our ECU Remap can give your ISUZU D-MAX an additional 36 horsepower (HP) and a 30% increase in torque (90 Newton meters or NM). This means your car will become more responsive, safer, and capable of handling situations like overtaking more efficiently.

Environment:

• Based on our estimates, you can save an average of 672 litres of fuel over a distance of 40,000 kilometres driven with your ISUZU D-MAX after our ECU Remap.
• Additionally, our calculations indicate an approximate reduction of 1801 kilograms of CO2 emissions into the atmosphere over 40,000 kilometres with your Isuzu vehicle following the ECU Remap.
• These numbers demonstrate the potential environmental benefits and cost savings achieved by optimising your ISUZU D-MAX’s engine performance through our ECU Remap service.
