VersaTune is a company founded by two Mazdaspeed6 owners who wanted to build a better tool to unlock the true potential of the Mazdaspeed MZR DISI 2.3l engine. As owners of Mazdaspeed vehicles and long time members of the Mazdaspeed community, we are dedicated to making the most of the platform.

VersaTuner is a full-featured performance engine tuning software toolset. VersaTuner is the all-in-one tool for recording, analyzing, modifying, and monitoring your engine’s performance.

VersaTuner currently supports these vehicles:

• 2006-2007 Mazdaspeed6 (United States/Canada), Mazda 6 MPS (Europe/Australia), Mazdaspeed Atenza (Japan)
• 2007-2009 Mazdaspeed3 (United States/Canada), Mazda 3 MPS (Europe/Australia), Mazdaspeed Axela (Japan)

Support for Mazda CX-7 is in beta stage and will be available very soon.

VersaTuner will be useful to different types of users:

• People who are new to engine performance tuning can use it to load pre-built maps onto their cars and enjoy increased performance. They will also be able to use maps obtained from fellow enthusiasts with similar modifications.
• To those with some tuning experience VersaTuner provides an easy-to-use yet extremely powerful toolkit to guide them through the entire tuning process: starting with data logging, graphing and analysis functionality and ending with tuning tips and flexible map editing tools.
• Hardcore enthusiasts will find features giving them serious control of the vehicle platform. VersaTuner makes it possible to disable certain self-tests, extend preset limits and accommodate modifications providing huge power, such as big turbos, large injectors, oversized intake parts and sensors, etc.

Intuitive interface and high usability of the software is one of our primary goals. No previous technical background is required - VersaTuner adapts to your skills and only provides relevant controls, resulting in a pleasant and effortless tuning experience.

• A Windows™ PC or laptop with a USB 2.0 port running Microsoft® Windows™ 2000/XP/Vista/7/8 32 or 64 bit
• A J2534 Pass-Thru device with version 04.04 DLL (DLL and driver are provided by the device manufacturer)

• Tactrix Open Port 2.0
• Drew Tech Mongoose ISO/CAN, (Ford) VPW/CAN

VersaTuner is a Windows™ application, so it runs on regular computers and requires no fancy hardware apart from an easily obtainable J2534 Pass-Thru device, used to talk to the car. It uses the same (SAE/ISO Standard) firmware upgrade method as official dealerships and the same hardware approved for use by third party service facilities to access the ECU (engine control unit). This method has been used by dealerships to update hundreds of thousands of ECU’s firmwares. It also has safeguard mechanisms to allow for a second reflash attempt in case of a failure.

VersaTuner uses the easily accessible datalink connector (also known as OBD-II port) located under your dashboard to the right of the steering wheel to connect to the ECU. There are no wires to cut or splice, and you do not have to take your ECU out. The whole process can be carried out in your garage.

No. A PC or laptop is only used while flashing a tune or logging live data. Once you have a tune that you are satisfied with, it is saved to the car and replaces the factory program. It stays on the car even after you disconnect your battery and until you replace it with another tune or return the vehicle to stock.

In data logging mode keyboard shortcuts and audible alerts are provided to keep distractions to a minimum. A compact netbook or tablet PC makes data logging even more comfortable.

"Piggy back" tuning solutions intercept the sensor signals flowing to the ECU and alter them to trick the ECU into thinking that the current conditions are different than they really are. For example, when increasing the airflow sensor readings, "piggy backs" hope that the ECU will increase fuel flow. However, modern ECUs have sophisticated control algorithms and "fooling" them is challenging and often leads to suboptimal results.

In contrast, VersaTuner works on a different level. It directly modifies the logic that is contained in the ECU. The result is the same as if done by the manufacturer. The possibilities are only limited by mechanical constraints.

What is more, VersaTuner is compatible with all "piggy back" solutions, so if you have one that you like, but would like to remove certain ECU limitations, this is possible with the addition of VersaTuner.

No, before you use VersaTuner, you will have to uninstall any 3rd party reflash-based solutions from your car. While VersaTuner is installed onto your vehicle, it will not be compatible with other reflash solutions. The dealer will not be able to upgrade your firmware either. However, upon uninstalling, the car will completely revert to stock state without any trace of VersaTuner. Uninstallation from the car only takes a minute and you don’t have to uninstall VersaTuner from your computer.

The manufacturer’s minimum reflash count specification for Mazdaspeed ECUs is 100. However, in practice some users with similar hardware have had more than 1000 flashes without any side effects. In the future, VersaTune will only update portions of the ECU that need to be changed thus extending the lifespan of the flash memory.

Most people will find a tune that works well with their vehicle after trying only a few maps.

No. A vehicle with VersaTuner installed looks completely stock to emissions testing equipment and allows for accurate measurements. However if you have your catalytic converter removed and/or your tuning results in violation of emissions requirements, this may be detected.

During the installation process, the original OEM flash image is backed up to your hard drive. When you decide to uninstall VersaTuner, the backed-up original calibration will be written to the ECU, thus returning it to stock.

The location of the OBD-II connector in the Mazdaspeed is a mixed blessing. It is easy to access for the type of diagnostics intended by the manufacturer. But, if you intend to drive the vehicle with a J2534 pass-thru adapter connected, you need to move the cable for safety's sake.

There are two options available. A right angle adapter cable is available from numerous sources, typically for under $20. This will substantially reduce the distance that the cable protrudes from the factory OBD-II connector. Search for a J1962M - J1962F right angle adapter.

The other option is to remove the factory OBD-II (J1962F) connector from it's mounting location. There are two tabs, one on each side of the connector, which when pressed in allow the connector to be backed out of the mounting bracket. Once removed it can be connected to the J2534 pass-thru device and safely tucked behind the center console. Be sure to secure and support the cable so it does not hang from the wires or come loose while driving.

Whichever solution you choose, be certain that the pedal assembly is unobstructed and that the cable is not able to become tangled around your feet. SAFETY FIRST !!

VersaTuner is licensed per VIN code. A single license of VersaTuner will only install and operate on the vehicle with the matching VIN code. Windows application can be installed on any number of computers, though. The J2534 PassThru cable can be used on any number of vehicles.

Volume licensing for professional tuners will be available soon.

Within 2 business days after your payment is processed, you will be provided with a personal download link for VersaTuner. Your version of VersaTuner will only work for the VIN you specified during the ordering process.

We don’t provide VersaTuner on CDs or DVDs, but your download link will always be available. In order to use VersaTuner you will also have to obtain a J2534 PassThru compatible adapter.

No, VersaTuner licenses are not transferable at this point.
