KTuner Flash-based system for 2021-2023 Acura TLX Type-S.  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!

Part numbers for usable ECUs include:

2021-2022 TLX Type-S:

• 37820-6S9-A51 through A59

2023 TLX Type-S

• 37820-6S9-A71 through A73

What is included with the KTuner Flash system?

• 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/

Do I need anything else to use this system?

Recommended For Vehicles With Hardware Modifications Or Located In Cold Climates

Application Notes:
We’ve found boost control on this application to vary wildly from vehicle to vehicle, even on the factory tune. Some users in cold weather and cold intake/coolant/oil temperatures together may experience a momentary “cut” if logged actual boost pressure exceeds the ECU’s target.  We have retained the overboost protection feature for safety.  This will feel like a very short substantial reduction in power, usually followed by an upshift to the next gear. If this occurs we recommend trying a tune with midrange dampening.

No additional tuning can be changed at this time
