Hello!
Been lurking for a bit here and brought a Stinger home about two weeks ago, partly due to the info and feedback that I've read in this thread and the original ECS10 one.
I came from a tuned and lightly modded 2016 IS350 with AVS (the Lexus version of our ECS). The suspension was one of the biggest thing on that car that I loved and knew the Stinger, at least stock, was not even in the same handling class with. That said, my lease was almost up and the time seemed right for something different, so I decided to do some additional follow-up test-drives.
The IS with AVS is extremely balanced, somewhat akin to the older generations of BMW 3-series; most of what it accomplishes is through extremely polished rebound and damping profiles as it is by nature rather softly sprung. At the same time, I could tell after test-driving a couple Stingers that what I was feeling was primarily due to the suspension curves. The Stinger was purchased knowing that this module existed and allowed for the control it does. I would have likely picked a different car without the ECS10 being available.
Back to the present and I received (thanks to the
forum store) and installed my module yesterday afternoon at lunch - what a tremendous difference. The stock Sport and Comfort settings in the app were already a very noticeable improvement, quite obvious not even a half block down the street.
For the advanced settings, I decided to start with Wayne's most current settings, extrapolated out to the 0KPH and 255KPH graph bounds that the app supports. For note, my car is a stock RWD GT1 (for now, except for the module

).
First impressions were something along the lines of "Wow". This is closer to what Kia should have released this car tuned to. I can't overstate how much this module is capable of improving and cleaning up the stock ECS calibration. I will definitely be doing some tweaking of my own with it as well, given time.
Thanks a bunch to Wayne and everyone else for putting the time and effort into refining their own profiles and sharing with everyone here, and for xot1 for bringing this mod to everyone's attention.
