Welcome to KTuner!

What is KTuner?
KTuner is a new tuning solution for late model J, K, and L series applications. KTuner was originally designed for use on the RSX platform, but can be used on a variety of applications including newer flash based vehicles up to current model year.
See our vehicle list for more platform specific info.

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

What can I do with KTuner?
KTuner allows full tuning of ignition, fuel, cam angle, and additional supporting parameters. Paired with essential datalogging parameters at high speeds, KTuner can be utilized to tune your application properly. KTuner also has custom developed features that can help you achieve your tuning goals beyond the factory capabilities.

What kind of hardware does KTuner require? How much is it?
For the older vehicles we have in-ECU hardware that gets installed directly into the ECU. For newer flash based vehicles we have hardware that plugs right into your OBD2 port. For more information and pricing see our KTuner products page.

I just want a reflash. Where can I get that?
A KTuner dealer can reflash or dyno tune your ECU without the additional price of the end user system.
