T93 failed to retrieve flash data on initial read

[jlaudio11]

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.

I know this is an old thread but I need HELP! I've got the same issue. I got my original TCM back from HP Tuners unlocking service and it won't read the tune file. How did you get this sorted out?

Any luck OmarR? Were you getting a prompt to have hpt unlock it even after they supposedly did?

Well,,,, first post,, new to HP Tuners & normally not a person to complain but...........

Just spent a bit of time money so I could tune my 21 High Country with this T93 TCM.
Try to read it & get a downloaded generic file because it will not read the module with a message stating something like "I can modify this generic file if I wish"
That's real nice
I don't think I am ready to try & write an unknown file to my vehicle & take the chance of bricking my transmission if I cannot even read it.

Would be nice if we were told of this issue BEFORE spending the time & money to have the controller unlocked....... just to find out that apparently it cannot yet be read unless I am missing something?

try reading just the tcm ..so when you have t93 you should also have a e90/e93 pcm which will require umlock services as well

Thanks but they are both "unlocked" I can read the ECM not the TCM
Tried reading both & reading individually & the TCM will not read
According to HP Tuners you cannot read the TCM have to use the generic file they send & use that to write to the TCM
So,,, you get,, hopefully a good generic factory tune to modify every time you want to do a change if you try to read.
Haven't tried it yet but am assuming if you save your tunes as you should you could modify the saved one & write it to the system but at this time according to HP Tuners cannot read what is in the truck

Saw this thread got pulled up just now, sorry I didn't see it before. I had to upgrade vcm suite to the latest beta to read the tcm after getting it back from hptuners.
