Install very straightforward and no surprises. Raised and move forward both passenger and driver's seat. Disconnected battery negative under passenger seat then removed old/installed new suspension controller under driver's seat. Harness connector locks will slide outboard from each other, as they do this will also eject harness from module.
No errors and everything works as usual upon startup. Limited seat time, but works just like most reported on the hellcat forum. Auto/Street mode firms up when taking cloverleaf's at speed and upon moderate to aggressive braking - immediately noticed flatter cornering and reduced nose dive. Not sure if this is possible, but seems like it's even softer at crawl speeds. For example when entering/exiting my driveway from the roadway there is a ~1" lip that causes a slight rocking motion - now it seems like it rocks a bit more.
Sport and Track modes are softer and more comfortable (compared to factory controller) if your just "cruising" but quickly adapts/firms up based on vehicle dynamics. Did not test the suspension launch mode yet but expect it to be effective based off what it has done so far!
IF I were to have a negative, it SEEMS like at 75ish speeds and above, Auto/Street mode firms up a bit too much while cruising for my liking. Again, I don't have a lot of seat time with this module yet, and sporadic seat time overall with the truck (owned since 2018, with 8000 miles). Once the run-flats go in the trash this setup will probably feel perfect.
I have stock suspension except BlackOps rear trailing arms, stock run-flats and 64 lbs unsprung weight reduction (which probably also affects damping characteristics).
I just got the software, so I'll try to pull the existing settings and share.
