What are the reasons for tuning a stock Mazda RX-8?

While a stock Mazda RX-8 is a fun car to drive, many people would love to have more acceleration and quicker throttle response. Those who race it would benefit from additional features like launch control and no lift shifting (also known as 2-step). Others want to increase the longevity of the rotary engine by adjusting the oil injection amount or remove the rev limit and speed limit. All of that and more can be achieved by tuning the ECU with VersaTuner.

Is Mazda RX-8 tuning safe?

Reflashing the ECU is almost as simple as updating your phone's software. VersaTuner uses the same protocols used by dealerships when updating the factory tune. Easily connect your computer to the car via the the OBD-II port, so there is zero need to remove any parts or splice wires. Our prebuilt tunes have been carefully designed and tested on the dyno so that your engine always operates within safe limits. And your factory tune is backed up, if you ever need to go back to stock.

Is ECU tuning necessary after performance parts have been installed?

Modern engine computers are programmed to produce consistent performance in all operating conditions. While many aftermarket part makers claim it is enough to upgrade the intake or exhaust to make the car faster, the actual gains may be disappointing. The ECU will still run the factory tune optimized for factory hardware and it is necessary to reprogram it to make it extract the additional power allowed by hardware mods. Stage 2 modifications like installing a turbocharger or supercharger are not possible without a custom Mazda RX-8 ECU tune.

I have no tuning experience, but I just want to make my Mazda RX-8 faster. Can I still use VersaTuner?

The pre-built tunes included with VersaTuner can be flashed by following simple instructions shown on the screen. No prior tuning experience or technical background is required, and you can complete the whole process on your own in under an hour (subsequent reflashes take just a few minutes).
