The engine control unit (ECU), is the on-board computer in your car. It’s in charge of controlling several unique functions of the engine. They include the ignition timing, turbo boost pressure, fueling, throttle position, and many other factors.
Just like all computers, the ECU also has its software with distinct settings. These settings can be tweaked to modify the vehicle’s performance. This procedure is called ECU flashing and it’s one of the best ways to maximize the performance of any application.
The ECUs of modern automobiles are built with fixed settings, since the manufacturer doesn’t want average consumers playing with engine settings. More often than not, however, the settings are not optimized very well.
1. Better Engine Power
Although an ECU flash won’t magically morph your minivan into a Ferrari, you will still feel a significant improvement in power, especially for turbocharged cars. Every driver is unique when it comes to the kind of power enhancement they want from their vehicle. Some drivers prefer a higher torque output and some favor a more responsive throttle.
2. Simple Tuning
Uninstalling the on-board computer of your vehicle is a pretty easy job that needs just a few simple hand tools. Once you have uninstalled the ECU, you can then ship or hand-deliver it to any professional tuner that you want, such as VR Tuned.
Once the tuner is done flashing the ECU, you can just re-install it back to your car and experience the noticeable boost in performance. In many cases, the entire process can be done through the OBDII port, which doesn’t require ECU removal.
3. Better Fuel Economy
Amazingly, you can flash your car’s ECU and enjoy better mileage as a result. You still have to drive it efficiently, however. The improvement in fuel efficiency mainly comes from improved fueling and ignition, which results in a more efficient fuel burn.
Regardless if you’re a car enthusiast who wants to enjoy an increase in power or simply desire to maximize your car’s fuel efficiency, an ECU flash will help improve the driving capabilities and responsiveness of your vehicle.
