Who is KTuner?

Back in the day, tuning a vehicle was done using some basic shop tools like a screwdriver. You can adjust the carburetor by turning a few screws, and you are good to go. But as automotive technology evolves, so is the tuning equipment. Nowadays, modern vehicles require a special tool for you to fine-tune your vehicle to its optimum performance. It is what KTuner offers.

KTuner is an ECU research and development solution for late model J, K, L, and R series vehicle applications. KTuner can be applied by part manufacturers in order to achieve C.A.R.B. and E.O. certifications.  

It can also be used by individual developers working under new development exemptions from the Library of Congress’s Copyright Office, allowing them to delve into the software that runs on a given property or automobile for R&D reasons. This particular software is for offroad use only. 

Designed For Racing

Many of KTuner’s products are also solely intended for racing competition only. They are not legal for use in highway or street vehicles or other non-racing competition offroad vehicles. Vivid Racing will have a memo under the specific product saying so, and purchasing such an item will require you to sign our Vehicle Compliance Waiver.

What Can You Do with a KTuner?

KTuner grants the ability to properly tune your vehicle’s ignition, cam angle, fuel, and additional parameters to meet particular emissions standards. The advantage of today’s tuning equipment is that you can adjust your car’s tune based on your requirement. 

Unlike carburetors, where you are limited to what the fuel mixture screws can provide, modern tuning equipment can adjust all vehicle parameters. With just a few touches of a button, you can have endless tuning capability perfect for those who want the best out of their vehicle.

Your Tuning Expert

When paired with essential data logging factors at high speeds, KTuner can be used to test and develop multiple vehicle platforms in the development of emissions-compliant, legal aftermarket performance products.

To summarize, these tuning systems not only lock a vehicle’s full potential but also allow you to run parts that you otherwise may not have been able to use. It includes high-flow intakes and downpipes or even full turbo systems. 

For Normally Aspirated And Turbo Cars

For cars already equipped with a turbo, you can merely raise the boost to give you some serious gains without breaking the bank. You can also extend the RPM limits and remove a vehicle’s speed governor. With a KTuner, you can also tune your car for increased horsepower and more efficiency (with a better mpg). The options are virtually limitless, as some vehicles have even implemented selectable tunes with just the flip of a switch.
