KTuner Flash-based system for 2019-2023 Acura RDX 2.0 Turbo. The KTuner Flash system allows you to reprogram/reflash your stock ECU directly over your OBD2 diagnostic port. No need to remove your ECU, etc. Simply plug the KTuner Flash system into your OBD2 port under your dash and reflash or tune your car using the KTuner software. Using the KTuner Flash system, you can retain all of your factory driveability, emissions, and reliability, while still being able to tune your engine for modifications (ie: intake, exhaust, boost increases, etc). The result will be a much better running engine with increased power!

• KTuner hardware (part that plugs into your OBD2 port)
• USB cable (plugs into your laptop on one end, and into the KTuner hardware on the other end)
• Pair of KTuner window decals
• KTuner software (download for free here: http://ktuner.com/downloads/)
