Welcome to KTuner!

What is KTuner?
KTuner is an ECU research and development solution for late model J, K, L, and R series applications. KTuner can be used by part manufacturers to achieve C.A.R.B. and E.O. certification. KTuner can also be used by individual developers working under the pretenses of new development exemptions from the Library of Congress’s Copyright Office allowing you to dive into the software that runs on your own property, including automobiles, for research and development purposes. This software is for off-road use only.
See our vehicle list for more platform specific info.

What does the software look like?
It’s pretty cool and very configurable. Take a quick look on our software overview page.

What can I do with KTuner?
KTuner allows the ability to properly tune ignition, fuel, cam angle, and additional supporting parameters required to meet emissions standards. Paired with essential datalogging parameters at high speeds, KTuner can be utilized to test and develop multiple vehicle platforms in the development of emissions legal aftermarket performance products.

What kind of hardware does KTuner require? How much is it?
For the older swap vehicles we have in-ECU hardware that gets installed directly into the ECU for direct developmental access to the main processor. For newer flash based vehicles we have J2534 compatible hardware that plugs right into your OBD2 port. This J2534 interface allows you to develop your own applications to access ECU information directly for research and development purposes. We only allow our proven compatible J2534 interface to be used with our software so that it is guaranteed that you can flash back to the factory software when testing has completed.
