Toyota diesel engines are renowned for their reliability and longevity. However, even the most durable engines need to be maintained in order to perform at their best. That’s where ECU remapping comes in, and why it’s important to have your ECU remapped in regular intervals.
As any performance enthusiast knows, your diesel engine’s output will naturally wane over time. And much like your annual service, having your Toyota’s ECU remapped at the right km travelled will help ensure it performs well throughout the course of its life, as well as prevent unnecessary component wear or reductions in fuel economy.
If you have noticed a decline in your engine’s performance or are suddenly spending more time at the servo, a good place to start figuring out the cause is checking when last your Toyota diesel was tuned.

Why Remapping Your Toyota’s ECU Matters
ECU remapping is the process of altering the factory programming of your engine control unit (ECU) to improve performance, drivability and fuel economy. Just Autos is Australia’s premier Toyota diesel tuning experts, and we can tell you from experience that a well-tuned ECU will not only improve your engine’s output but also make it more efficient.
Over time, as your engine wears and changes are made to its components or operating conditions, its original tune will become less effective. A new map will take into account these changes and optimize your engine accordingly.

How Often Should You Get Your Toyota Diesel Tuned?
Ideally, you should have your ECU remapped every 100,000km. However, if you have noticed significant changes in your engine’s performance or fuel economy, it’s best to get it checked sooner rather than later.
What Happens if You Don’t Get Another Remap Done?
If you neglect to have your Toyota’s ECU remapped, you’ll notice a gradual decline in performance as well as an increase in fuel consumption. In extreme cases, it can even lead to engine damage.
So, if it’s been more than 100,000km since your last ECU remap, or you’ve noticed a drop-off in performance, it’s time to book in for a tune-up at Just Autos!

Do You Need ECU Remapping if You’ve Had Modifications or Upgrades Fitted?
In short, yes. If you’ve made modifications or upgrades to your vehicle, it’s important to have the ECU remapped to ensure everything is working in harmony. Fitting aftermarket – or genuine – performance parts to your vehicle will naturally alter the way it performs, and a good ECU remap will help ensure that these changes work together seamlessly.
We can tailor a map specifically for your vehicle that takes into account any modifications or upgrades that have been made.

The Performace-Enhancing Benefits of ECU Remapping
There are many reasons to have your Toyota’s ECU remapped, but the two main ones are improved performance and fuel economy.
A well-tuned ECU will release the full potential of your engine, giving you more power and torque when you need it most. Whether you’re towing a caravan up a steep hill or merging onto the highway, you’ll notice a significant difference in how your engine responds.
You’ll also see a decrease in fuel consumption as your engine will be running more efficiently. Over time, this can amount to considerable savings at the pump!
