VersaTuner is tuning software for Mazda vehicles. It is a Windows application that allows reflashing/remapping (chip tuning) of Gen 4 Mazda MX-5 Miata engine ECUs, data logging, tune editing and diagnostics.
Unlike other apps that target only professional tuners, VersaTuner makes Gen 4 Mazda MX-5 Miata 1.5l SkyActiv-G tuning accessible to everyone. Included 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 4 Mazda MX-5 Miata today.

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 4 Mazda MX-5 Miata 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 4 Mazda MX-5 Miata ECU is provided below. As we continue to analyze the ECU logic and develop new tunes, we may make new maps available.
NOTE: The exact list of tables available for your car may vary depending on the ECU manufacturer and software version.
When you need to analyze how your Mazda performs before or after ECU tuning, you will drive the car and record the values of different parameters. All editions of VersaTuner (even Free!) include important Mazda-specific logging parameters that are available to official Mazda service centers and are not usually included in cheap universal logging devices or apps.
Here is a list of all currently available data logging parameters (also known as PIDs) for your Gen 4 Mazda MX-5 Miata.
