2013-2017 Mazda CX-5 (Gen 1, KE) ECU Tuning Software and Ready to Flash Tunes

Engine: 2.5l SkyActiv-G

All regions supported, including USDM, EUDM, JDM and AUDM.
Manual and automatic transmissions supported.

VersaTuner is tuning software for Mazda vehicles. It is a Windows application that allows reflashing/remapping (chip tuning) of Gen 1 Mazda CX-5 engine ECUs, data logging, tune editing and diagnostics.

Unlike other apps that target only professional tuners, VersaTuner makes Gen 1 Mazda CX-5 2.5l SkyActiv-G tuning accessible to everyone. Included dyno-tested prebuilt tunes allow adding horsepower or increasing fuel economy with just a few clicks. More experienced users can use the Tune Editor to get access to dozens of adjustable engine tables, maps and parameters. Professional tuners can use VersaTuner Professional to tune multiple vehicles and build locked and encrypted tunes that protect their Mazda tuning know-how.

VersaTuner can be ordered globally and can be downloaded immediately after purchasing. All you need is a Windows laptop or tablet, a compatible hardware interface (cable) to connect your computer to the car and you can start tuning your Gen 1 Mazda CX-5 today.

Gen 1 Mazda CX-5 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 for the Gen 1 Mazda CX-5, 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 Gen 1 Mazda CX-5 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 were developed on real vehicles and their performance gains were measured on a chassis dyno. Our tunes can also be downloaded and edited and serve as a great starting point for custom or high power tunes. With our prebuilt tunes, Gen 1 Mazda CX-5 tuning has never been easier!

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 1 Mazda CX-5. 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.

Push the Limits

  • Eliminate the artificial power limits of the stock ECU
  • Change the speed limiter
  • Change the rev limiter
  • Make accelerator pedal more responsive
  • Use uprated sensors and MAF housings

Crackle and Pop Tunes

We have built crackle and pop (also known as pop and bang) versions of our performance tunes, if you are looking for a head-turning sound when you release the accelerator. The tuning is well within the safe limits and should not cause any damage to your engine. And you can use the tune editor to customize the intensity levels or add crackle and pop to your custom tunes, too.

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.

Available Gen 1 Mazda CX-5 (2.5l SkyActiv-G) Tunes

This is a list of currently available free VersaTuner tunes for 2013-2017 Mazda CX-5 (Gen 1, KE) with the 2.5l SkyActiv-G engine. All these tunes can be flashed both with VersaTuner Lite and the full version. These tunes were professionally developed on real cars and their performance was measured on a chassis dyno. New tunes are regularly added based on demand. If you can't find a suitable tune, you can contact a professional tuner or an e-tuner working with VersaTuner. You can also create a custom tune yourself with the full version of VersaTuner, using any of these tunes as a starting point.

Editable Tables and Constants

Full version of VersaTuner includes a tune editor that allows you to change the aspects of your Mazda ECU operation related to power delivery and fuel efficiency. Tuning your Gen 1 Mazda CX-5 ECU is done by changing the tables and constants that the ECU uses internally to calculate load targeting, fueling, injection, ignition, interpret sensor values, etc.

A list of all currently available tables and constants (also known as maps) for tuning the Gen 1 Mazda CX-5 ECU is provided below. As we continue to analyze the ECU logic and develop new tunes, we may make new maps available.
