Multiple Honda/Acura Fitments KTuner V1.2 End User Flash Kit by KTuner

With the KTuner system, you can finally get that flawless tune without the hassle. This package includes three starter maps, 16.5PSI, 18 or 21 PSIs and a tune switch that can be customized for your specific driving conditions by a ECO button. Accelerate faster and farther than ever with our wide range of tuning options. The KTuner V1.2, the latest technology in tuners, allows you to precisely control engine response for any type or level of driving, from city traffic all the way up through race track competition!

Highly recommend

Best thing for your car! Get this before anything else.

This was the best mod done to my 2.0 NA and now my SI. Even the base maps wakes up the car compared to stock. Totally worth it.


Simple to use and it adds power for sure

100% worth it, the ots tunes are good, and especially if you plan to do more in the future, it make the tuners job easier, would buy again for another car
