The goal of our tune is to increase power without sacrificing the reliability of your Skyactiv-G engine. Of course, we don’t just make your car run super aggressive, as that would reduce long-term reliability. The result is slightly more aggressive ignition timing, air/fuel ratio, and reduced limiters, as well as many other small changes. With the VR Tuned ECU flash, you are taking the stock parameters the ECU tries to stay within and change them. Luckily, our tuning division, VR Tuned, offers a solution to this conservative tune. They hold power back to improve emissions and keep the engine extra safe. Mazda’s tune is very conservative, holding air/fuel ratios and ignition timing way back. Where Mazda left performance on the table is with the stock tune.
Skyactiv-G is almost entirely hardware related, as most of it relies on reducing cylinder temperatures to reduce the possibility of knock. Most naturally aspirated production cars have a compression ratio of 12:1 or less, however, Skyactiv-G engines have a compression ratio of 14:1! They worked hard on making that high compression ratio possible, but even with all that work on the Skyactiv-G engine, they still left some performance on the table. What’s awesome about the Skyactiv-G engine is the high-compression ratio. The Skyactiv-G engine under the hood is very efficient, but it’s a little underpowered for the Mazda 6. The Mazda 6 is incredibly popular thanks to its affordable price and larger size. For many people, those Mazdas simple don’t fulfill their needs. As an enthusiast, when you think of Mazda, you might think about the Miata, RX7, RX8, MS3, MS6, etc.
