ECU tuning/remapping software for:

2013- Mazda3

Supported engines: 2.2l SkyActiv-D diesel (150 HP and 175 HP versions)

Gen 3 Mazda3 Tuning Made Easy

VersaTuner has been carefully designed to be easy to understand for first time users and at the same time allows experienced tuners to work efficiently. All features are accessible from one Windows app with a sleek and modern user interface. Guides and wizards lead you through the important processes. The UI is optimized both for touch-based use on tablets as well as laptops and desktop PCs.

Safe and Reliable

VersaTuner is a true reflashing (remapping/chip tuning) solution, not a "piggyback" controller. No wires need to be spliced and all built-in safety features of the ECU are retained. It uses the same flashing methods that are used by dealerships when updating your ECU. Built in recovery feature can flash the ECU even in the unlikely event of power failure. Your stock calibration is backed up, so you can go back to stock at any time.

Online Tune Database

A growing selection of prebuilt tunes is available right from the app. If you have a stock or mildly modified vehicle, flash a suitable tune with a couple of clicks and enjoy. All our tunes can be downloaded and edited and serve as a great starting point for custom or high power tunes.

Tune Editor

VersaTuner includes an advanced tune editor allowing you to edit a multitude of tables, maps and constants and customize existing or create custom tunes for your Gen 3 Mazda3. It comes with a ton of productivity features, such as tune comparison, visualization, interpolation and automated translation of descriptions to 110+ languages.

Dashboard & Log Viewer

Virtual dashboard allows you to view and record all the vital engine parameters simultaneously. Analyze recorded logs later using a graphical log viewer or export them to Excel or Virtual Dyno.


Read and clear DTCs from multiple modules, not just your engine ECU. A vast number of standard and Mazda-specific DTCs is supported.

Features & Extras

More Power, Faster Acceleration

VersaTuner allows you to safely and easily increase the horsepower and torque of your engine. That results in faster launches and better 0-60/0-100 times.

After driving a tuned car you will never want to go back to stock again!*

* going back to stock only takes a couple of minutes with VersaTuner, when needed

Full Potential of Modifications

Have you fitted an uprated intake or intercooler? A bigger turbo and exhaust?

On modern cars, upgrading parts alone will not have a significant effect unless accompanied by changes in ECU tuning. VersaTuner allows you to realize the full potential of your mods. Update the tune easily as you add new parts in the future.

Upgrade Your Engine

150 HP and 175 HP versions of the Mazda SkyActiv 2.2l diesel engine are mechanically identical, with ECU tuning being the only difference. Even if your car has the low power engine, VersaTuner will allow you to unlock the hidden potential and reach the same horsepower and torque levels that are achievable by the high power version. And 175 HP is just the start!

Push the Limits

  • Change the speed limiter
  • Change the rev limiter
  • Increase boost pressure
  • Make accelerator pedal more responsive
  • Use large turbos, MAP sensors and MAF housings

Disable Unwanted Codes

Have you disabled or removed certain features from the car for track use and now have the check engine light (MIL) constantly on?

With VersaTuner you can disable specific diagnostic trouble codes and have a clean dashboard that will only warn you when a real issue occurs.

Special Tunes

Anti-theft tune will prevent the car from starting and keep the intruder confused, offering you peace of mind when you need to leave the car for a long time.

Valet tune significantly reduces the power and speed of the car and is perfect for those situations when someone needs to borrow your precious vehicle.
