F.A.Q

What is VersaTuner?

VersaTuner is a powerful flash tuning software designed specifically for a wide range of Mazda vehicles, including Mazdaspeed, Mazda MPS, CX-7, RX-8, Mazda3, Mazda6, CX-5, and MX-5/Miata models.
It runs on Windows and enables you to reflash or remap (also known as chip tuning) the ECU on engines such as the Mazda MZR DISI, rotary, SkyActiv-G, and SkyActiv-D. VersaTuner also supports data logging, tune editing, and diagnostics.

How long does the tuning process take?

Unlike many others, we typically complete most tunes within a few hours or the same day. If any issues arise that can't be resolved immediately, we pause the process and resume the tune once the issue with the vehicle is fixed.

Do I need to do any logging or make adjustments myself?

Nope—that’s the best part. We handle the entire tuning process personally, from start to finish. You won’t need to worry about sending logs or making any changes on your end.

Which vehicles are supported?

VersaTuner supports a variety of Mazda models. You can view the full list here:

What is the tuning method?

We primarily offer street tunes and dyno tunes, depending on what works best for your setup. E-tunes may be available in certain cases, depending on the circumstances.

What happens if I add or change modifications after tuning?

If you install basic modifications after your vehicle has been tuned, some adjustments will be needed, and a touch-up tuning fee will apply.
However, if you upgrade to major components—like a built motor, upgraded turbo, or other significant performance parts—a brand new full tune will be required.

What is Knock Retard (Ignition Correction in Fords), and Should I Be Concerned?

Knock Retard (KR), also known as ignition correction in Ford vehicles, refers to the engine’s response when the PCM (Powertrain Control Module) detects detonation—an uncontrolled combustion event within the cylinder. This is a normal function in all internal combustion engines.

When detonation is detected, the PCM quickly reduces spark advance (timing) to prevent potential engine damage. This process is called knock retard. Modern PCMs are extremely fast and precise at identifying and managing knock, helping ensure engine safety and performance.

From the factory, Ford’s PCM logic is designed to operate at the threshold of knock. This allows the engine to run the maximum amount of spark advance safely, which results in optimal power and fuel efficiency for the given fuel quality.

It is common to see some knock retard during part-throttle driving, and in most cases, it is harmless—especially when the engine isn’t under heavy load. If you notice a brief spike on your monitoring device while cruising, it's often just sensor noise and nothing to worry about.

As a general guideline:

  • Up to 2.0 degrees of knock retard under wide open throttle (WOT) or heavy load is considered acceptable.

  • However, the goal is always to keep KR as minimal as possible for ideal performance.

If you're ever unsure or see consistent high values under load, it’s a good idea to consult your tuner.
