Has anyone tried reading a Regal TourX? I know the LTG E80 is supported on other platforms, and I have been dabbling with the one in my wife's 2.0T 18' Equinox successfully, but per HP Tuners supported vehicles list, it's not supported (yet). I don't have a 2018+ Regal, otherwise I would just try it myself ; )
I'm assuming engine support would be the only possibility, as unfortunately they use an 8 Speed Aisin AWD transmission that I'm sure is a baste** child just like the V-Sport CTS...
