VersaTuner is tuning software for Mazda vehicles. It is a Windows application that allows reflashing/remapping (chip tuning) of Series 1 Mazda RX-8 engine ECUs, data logging, tune editing and diagnostics.
Unlike other apps that target only professional tuners, VersaTuner makes Series 1 Mazda RX-8 1.3l RENESIS 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 Series 1 Mazda RX-8 today.
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.
VersaTuner is a true reflashing (remapping/chip tuning) solution for the Series 1 Mazda RX-8, 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.
A growing selection of prebuilt Series 1 Mazda RX-8 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. With our prebuilt tunes, Series 1 Mazda RX-8 tuning has never been easier!
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 Series 1 Mazda RX-8. It comes with a ton of productivity features, such as tune comparison, visualization, interpolation and automated translation of descriptions to 110+ languages.
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.
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
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.
Perfect launches have never been easier. VersaTuner limits the launch RPMs so that the only thing you need to worry about is releasing the clutch at the right moment. With no lift shifting, you can go through gears without releasing the accelerator and loosing boost. All settings are fully adjustable!* manual transmission only
The OEM Mazda RX-8 ECU tuning tables are limited to low loads of naturally aspirated engines and are quickly maxed out when a turbo/supercharger is installed. VersaTuner allows you to edit the axis values of tuning tables, so you can precisely control the engine even at higher than stock loads or RPMs.
It can also automatically interpolate the table values so that engine operation at normal loads remains unchanged. All this allows you to create robust and accurate tunes for turbocharged or supercharged Mazda RX-8 vehicles.
Mazda RX-8 ECU has a built in flash counter that will lock the ECU after a certain number of reflashes.
Unlike some other tuning tools, VersaTuner can reflash the ECU without incrementing the flash counter. This lets you remap your car thousands of times* without the need to replace the ECU.* limited by the physical durability of the ECU flash memory
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.
This is a list of currently available free VersaTuner tunes for 2003-2008 Mazda RX-8 (Series 1) with the 1.3l RENESIS engine. All these tunes can be flashed both with VersaTuner Lite and the full version. 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.

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 Series 1 Mazda RX-8 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 Series 1 Mazda RX-8 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.
