ECU (Engine Control Unit) remapping — or diesel tuning — is when your original 4WD computer software file is replaced. The ECU remapping, or re-writing procedure over-writes and replaces the standard manufacturer’s software in the ECU, overwriting it with new updated software which can be programmed to optimise your 4WD’s overall performance — we make sure to keep a backup of your original file should you ever wish to revert to default settings at any time.
The benefits of the ECU Remapping can include an increase in power and torque, better fuel economy with enhanced sharper throttle response, and a much smoother and more progressive delivery of power. You get to be in control of your vehicle’s efficiency, and the qualified technicians at Diesel Performance Tune are here to help you achieve peak engine performance.
The power of ECU tuning
All vehicles today have ECU’s. The ECU is programmed by the manufacturer to operate and run the engine. When your 4×4’s ECU is “remapped”, we basically remove the software files that control the tuning of the engine, modify them according to the tune type we are looking for, and then put the new files back into the computer, overwriting the standard files. This is usually done through the vehicle’s standard communication plug (OBD plug or serial port) of your 4WD.
This new version of “tuned files” will enhance the engine’s performance.
The ability to flash directly through the OBD port has brought the tuning industry on in leaps and bounds, and with constant development to the engine now being much quicker via the flash process, it has allowed us to develop some of the best tuning software in the country.
Reprogramming the vehicles ECU has several advantages and we believe with the right tune and qualified technician, an ECU remap will take your 4WD to the next level, here’s why:
