What is it and how does it work?
ECU Remapping is when your 4wd’s computer (Engine Control Unit) original software files are replaced. In simple terms, it’s like updating a software program on your computer.
A vehicle remap replaces the standard (default) software in the ECU, overwriting it with new, up-dated software which can be programmed to optimize your 4 wheel drives overall performance. The benefits of the ECU Remapping are, an increase in power and torque, better fuel economy with enhanced, sharper throttle response and a much smoother and more progressive delivery of power.
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 leaps and bounds, with constant development on 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 a number of advantages not at least is that we retain all of the manufacturers inbuilt safety features, we know our tunes will be reliable and won’t have your 4WD going into “limp mode”.
Additionally, reprogramming the ECU gives us the unparalleled ability to alter torque management tables, throttle mapping, boost pressure, fuel pressure & injector timing to name just a few… something no individual chip or module can come close to claiming.
The ECU Remapping, or Flash Tuning, technology is far superior to any single chip.
