    T93 failed to retrieve flash data on initial read

    Just got my unlocked t93 back from hptuners today and when I try to read the tcm I keep getting a failed to retrieve notification. I initially did the tcm replacement portions with vcm scanner before removing the stock tcm, then unhooked the battery and removed tcm, i sent it to hptuners, they sent it back, i plugged it in, hooked the battery back up and started the car. Everything worked fine, it went into gear etc then i tried to pull the file and it wouldn't work. I remembered that i never finished the tcm replacement with vcm scanner and then when through those steps with the unlocked tcm in place. I'm still unable to retrieve the data. Yes I do have an internet connection. I can still read the ecm fine, just like i have before, just seems to be an issue with tcm. I do have a ticket in with hptuners right now, but checking here also. Has anyone else had this issue?

    Have you gotten this issue figured out?

    I was discussing getting the TCM tuned in my 2021 ZL1, but my tuner cautioned me to wait due to there being issues with the T93 unlock.
