VersaTuner is tuning software for Mazda vehicles. It is a Windows application that allows reflashing/remapping (chip tuning) of Gen 1 Mazda CX-7 engine ECUs, data logging, tune editing and diagnostics.
Unlike other apps that target only professional tuners, VersaTuner makes Gen 1 Mazda CX-7 2.3l MZR DISI Turbo 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 1 Mazda CX-7 today.
Starts, Runs for 2 seconds, then stalls.
93US/98EU + Octane tune for stock or near stock vehicles. CAI or modded air box are OK. Stock DP is required. Provides moderately increased boost, revised fuel and spark, and throttle is opened over an extended range.
Substantially reduced output. 5000 RPM rev limiter. 100 MPH / 160 km/h speed limiter.
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-7 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 your Gen 1 Mazda CX-7 ECU is provided below. As we continue to analyze the ECU logic and develop new tunes, we may make new maps available.
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 1 Mazda CX-7.
