Tired of Feeling Left Behind?

You’ve been there - watching others fly past, their cars roaring with power, while your ride just can’t keep up. The frustration builds every time someone talks about their latest upgrade or leaves you in the dust at a meet.

One Upgrade, Endless Respect

Then it happened. You installed the K-Tuner. That first pull was electrifying - smoother shifts, instant throttle response, and pure adrenaline. Suddenly, your car wasn’t just a way to get around. It was a statement.

Welcome to the Brotherhood

Now, you’re part of it. The nods at meets, the envy from friends, and the shared stories of late-night runs. It’s not just about speed - it’s about being part of a community that lives for the love of driving.

How does the KTunerFlash V2.0 improve my vehicle's performance?

The KTunerFlash V2.0 allows you to optimize your vehicle’s ECU for improved power, torque, fuel efficiency, and responsiveness. With custom tuning options and pre-loaded maps, you can fine-tune your car to match your driving style and performance needs.

Will using the KTunerFlash V2.0 void my vehicle's warranty?

The KTunerFlash V2.0 is designed to be easily reversible. If needed, you can restore your vehicle's factory settings, minimizing any risk to your warranty. We recommend checking with your dealership for specific policies.

Is the KTunerFlash V2.0 safe to use on my vehicle?

Yes, the KTunerFlash V2.0 is designed with safety in mind, offering reliable and stable tuning solutions. It allows you to revert back to your factory settings at any time if needed. However, we recommend following the tuning instructions carefully and consulting with a professional tuner for custom maps to ensure optimal performance.

How long does it take to install and set up the KTunerFlash V2.0?

The installation process is quick and straightforward, taking approximately 15 minutes. Simply connect to your vehicle's OBD2 port, follow the instructions, and you're ready to go.

What vehicles are compatible with the KTunerFlash V2.0 Tuning Package?

The KTunerFlash V2.0 Tuning Package is compatible with a wide range of Honda and Acura models. For a full list of compatible vehicles, please refer to the KTuner compatibility chart on our website or contact our customer support team for assistance.

Do I need any special tools or equipment to use the KTunerFlash V2.0?

No special tools are required. The KTunerFlash V2.0 connects directly to your vehicle's OBD2 port, allowing you to flash and monitor your ECU using the provided software. All you need is a laptop with Windows to install the KTuner software and manage your tuning.

 Can I switch between performance maps on the go?

Stage One+ 2017 Si

You will not regret getting the KTuner V2 with the stage one+ tune. My 2017 Honda civic Si when from factory slow to what I feel like the si was supposed to be like. My throttle response is phenomenal, my car is much quicker, and I now feel like I’m driving an entirely different car! Thank you TSP
