We all know that while factory settings are enough for everyday driving, many performance enthusiasts are always on the hunt for that extra push. At Just Autos, we understand because we share the same passion! We’re always on the lookout for new and innovative ways to elevate your vehicle’s performance and capabilities.
That’s why we’re proud to introduce EasyTune into our repertoire – a revolutionary tool that transforms the way we read and write your vehicle’s ECU. With features like an inbuilt flasher, live tuning capabilities, and real-time engine data reading using PTCs and OBD functions, alongside live data logging, EasyTune is designed to optimise your vehicle’s performance with ease and precision.
Whether you’re a Toyota enthusiast looking to ramp up your performance or just eager to explore the latest in ECU technology, this post has got it all! Read on to learn more about this exciting new tool in our tuning process.

What Is EasyTune?
You might’ve seen the EasyTune logo in and around Just Autos and wondered what it’s all about. Easy Tune is a state-of-the-art web-based platform designed to read and write your vehicle’s ECU (Engine Control Unit).
As a web-based solution, Easy Tune provides unparalleled accessibility. Whether we’re in Australia or anywhere else in the world, we can log into EasyTune and use a pass-through dongle to live tune your vehicle. This flexibility allows us to explore a wide range of parameters, giving deep insights into your vehicle’s performance and allowing us to optimise it like never before.
This tool comes with an inbuilt flasher, live tuning capabilities, and the ability to read engine lines using PTCs (Programmable Timing Control) and OBD (On-Board Diagnostics) functions. One of the standout features is live data logging, which is crucial for real-time performance monitoring and optimisation.
Ultimately, Easy Tune is all about providing a seamless, powerful, and intuitive ECU management experience, helping us unlock your vehicle’s full potential.

A Closer Look At The Flashing Screen
When we talk about “flashing,” we mean the process of removing the existing software from the ECU, calibrating it, and then writing the updated software back into the ECU. This process ensures that your vehicle runs on the most up-to-date firmware, with our multi-mapping system seamlessly integrated.
Here’s an overview of how it works: We start by grabbing the latest firmware and integrating specialised multi-mapping system into it. This combination creates a complete unit that we then load back into your ECU. The flashing screen allows you to manage this process effortlessly, ensuring that your vehicle always runs on the latest firmware.
One of the advantages of this flashing system is the security it provides. Once we have flashed your car, no other shop can flash the ECU again. This ensures that any accidental tampering by other shops is prevented. However, should they need to revert to the original settings, you can easily download the original file from our website and use it to flash the ECU back to its original state.
Data Logging
Tuning without data is like driving blind. Without seeing the detailed numbers, it is challenging to pinpoint and address issues accurately. For years, Dyno tuning has been the go-to method, allowing us to verify fuelling and boost pressures. However, it has its limitations, only showing positive or negative gains without providing the in-depth data needed to make precise adjustments.
With data logging systems, we can see what the computer is actually commanding, the numbers it generates, and where any problems lie. This deeper insight allows for a more accurate and effective tuning process.
Unfortunately, many existing data tools log data at around 5 points per second (5 Hz), creating blocky and imprecise graphs. To overcome these limitations, we’ve developed our own data logger that logs data at an impressive 60 points per second (60 Hz), which is 12 times faster than other systems on the market. This high-resolution data capture allows us to see the smallest details and differences between runs, allowing us to fine-tune the ECU with unparalleled precision!
This is the secret to our tuning success. The ability to see and analyse detailed data means we can identify and fix issues more accurately, optimising performance to the standards we are so well known for.
Fine Tuning Data With Our Inspector
With data logging, there is a lot of data and numbers to get through – making it a challenge to dissect. Within our Data Logging system, we have the inspector, that takes this data and categorises them into distinct colour-coded categories: blue, green, yellow, and red.
Each category corresponds to different aspects of your vehicle’s performance and can help to identify issues such as boost pressure, fuelling efficiency, timing accuracy, and more. This simplifies the process of identifying issues or areas for improvement quickly and accurately – and is easy to read, even if you’re not an expert in data analysis!

OBD Functions
At Just Autos, we leverage OBD functions in EasyTune to streamline and enhance the tuning process. When we connect our laptop to your vehicle, we utilise OBD functions for various purposes, such as injector calibration or pilot relearn. However, to optimise efficiency and accuracy, we have developed a comprehensive list of OBD functions that we frequently use. These functions are pre-made templates tailored to common tuning tasks, simplifying the steps involved and ensuring consistent results.
DTCs (Diagnostic Trouble Codes)
We get worried when we see the dreaded orange light on our dash while driving. But what does it mean? That little orange engine-shaped light on your dashboard is your vehicle’s DTC warning light. It serves as an indicator that something needs attention in your vehicle’s system.
DTCs are thousands of codes, each corresponding to a different potential problem with your vehicle. These codes are categorised and stored in your vehicle’s memory, sometimes listed as pending when a fault condition is detected but hasn’t fully met the conditions to display.
With EasyTune we can not only read existing and pending DTCs but also clear them from the system, providing insights into your vehicle’s health. This minimises potential issues and maximises performance and safety on the road.
Pit Control
At Just Autos, one of our ongoing challenges has been optimising pit control, especially when it comes to our boost systems. This is especially important when it comes to tuning the VDJ 79 series, where it has been a challenge to get our duty and our pit control just right. It’s proven to be time-consuming, taking hours and hours of adjustment and testing.
Seeing the need for a more efficient solution, we have developed a new strategy to overhaul our pit control system. This allows us to accommodate the specific boost pressures we work with, rather than adhering to factory settings, which gives us highly repeatable and consistent boost levels across all applications.
With our refined strategy, we have not only reduced the time spent, but ensured better performance and tuning solutions.
Last But Not Least, Live Tuning
One of the best features of the EasyTune site is it’s live tuning capabilities. This means we can make instant adjustments to your vehicle’s calibration while the engine is running, eliminating the need for restarting the car and reflashing between tuning sessions.
Whether we’re fine-tuning on the dyno or directly on the road, changes can be made swiftly and effectively. Once adjustments are finalised, they can be saved directly to the ECU, ensuring that your vehicle operates with the latest optimised settings.
Live Tuning is pretty versatile and can leverage the full potential of factory ECUs. The sky is the limit to what we can achieve in term of performance enhancements and efficiency improvements!
Unlocking Your Vehicle’s Potential with Easy Tune
EasyTune offers an unparalleled suite of tools and features designed to optimise your vehicle’s performance with precision and ease. From live tuning capabilities that allow real-time adjustments to advanced data logging and diagnostic functions like DTC reading and clearing, we can extract the maximum performance from your vehicle.
