I?ve got an HPTuners MPVI 2+ and I?m having trouble reading my JTEC ECU. Is there no support for the JTEC 4.0?

Never mind, I’m an idiot. I got it.
For anyone that may stumble upon this post wondering if they can tune their 4.0L JTEC/JTEC+ WJ. You can. I successfully read my ECU on my 2004 Jeep Grand Cherokee 4.0L. It doesn’t explicitly state that you can, but I was able to. I hope this helps whoever it may.
