KTuner Flash-based system for 2021+ Acura TLX 2.0 Turbo.  The KTuner Flash system allows you to reprogram/reflash your stock Acura 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 drivability, emissions, and reliability, while still being able to tune your engine for modifications (ie: intake, exhaust, cam upgrades, etc). The result will be a much better running engine with increased power!
