Boost up your horsepower with an ECU Flash on your Genesis G series sedan. Tuning the 5.0L engine is possible with VR Tuned. An ECU flash alters the ECU programming directly to increase horsepower and torque while providing a better driving experience. Adjustments are made to speed limiters, throttle limiters, torque limiters, fuel maps, timing maps, boost maps throughout the entire file. The special Hyundai Kefico Continental Sim2K ECU uses a tricore processor which must be mailed in to bench flash. Check out the performance increase below!

What is VR Tuned?

VR Tuned (VRTuned.com) is the offshoot of globally known, high-performance retail parts specialists, Vivid Racing. VR Tuned products include everything you need from booster pedals, ECU flashes, and gearbox tuning to tuning accessories and complete tuning box kits.

Having had success in popular tuning chassis' such as the Subaru WRX STI, Mitsubishi EVO, and BMW M3, this was a natural progression of expansion in VR's repertoire of vehicles. As the tuning market boomed extensively in the early 2000s, Vivid Racing established a very strong presence online and throughout vehicle communities. When the recession came, Vivid Racing continued to grow and focus on the development of its products, distribution network, and most importantly, its customers. The diversity of vehicle products and services has allowed Vivid Racing to continue to strive for excellence while maintaining exceptional growth.

ECU tuning has always been an extremely important part of modifying and building vehicles. This is essentially the glue that brings the performance out of aftermarket products and packages to truly take vehicles to the next level. With this next stage in the company's footprint, VR Tuned was proudly launched in January 2014 and continues to grow to this day.

Our Tuning Expertise

As the tuning industry's tools became more accessible, so has the ability to partner and work with individuals to offer a unique service with added value. Working with several tuning companies over the years, we have experienced the upsides and downsides of the ECU tuning world. As it is our mission to offer unparalleled customer service and support, it is equally important to offer a great product that is tested, convenient to use, and priced within reason for the current demographic.

With a Mustang All-Wheel-Drive Dynamometer in-house at our Gilbert, Arizona facility, we have spent countless hours testing tuned files, the effects of different vehicle modifications, and learning how vehicles react to these changes. But most importantly, our product confidence comes in that we have owned these vehicles, daily driven these vehicles, raced these vehicles, and understand what the consumer is looking for. Our YouTube channel also features a host of videos showcasing our ECU and tuning products with before and after results as well as drive-by videos to demonstrate just how much more power and performance you can gain.

Why Choose VR Tuned?

VR Tuned products are used all around the world with satisfying results! VR Tuned ECU Tuning is done by altering the parameters to maximize output while keeping your vehicle safe and reliable with no check engine lights. VR Tuned offers the best and most efficient ECU flash over all of the competition. Our flashing is done via the diagnostic port which allows you to flash between the stock and tuned file. The flashing software gives you the convenience to easily flash your car and update files if necessary.

After careful testing, our VR Tuned flash adds power gains across the power band in both horsepower and torque that can be felt. What's more, our flashing takes roughly three minutes compared to the competition that takes almost 20 minutes! Basic bolt-on performance parts will not require a retune of your ECU as it will merely adapt to these mods. Other parts like colder spark plugs, boost tubes, or diverter valves are not required but can help performance. We can tune cars of all kinds, including JDM, EU, Australian, and USA cars for different types of octane and environments. It's important to note that we do not lock, "pot", or keep control of your ECU. If you decide to take it to another tuner for an upgrade, all flashing ability is retained.
