I have an autocal unit. I have already sent my TCM off to be unlocked. Can I tune my TCM with the autocal unit? Is there any support with efilive and the GM 8 speed transmission?

With an AutoCal, you'll need to go through your tuner to discuss options as you cannot build your own tunes with an AutoCal. The T87 depends on the year, you'll need to look at the supported vehicles page here: GM Supported Transmissions (http://www.efilive.com/gm-transmission-supported-vehicles)

"unlocked" ? Who did you send it off to, to be "unlocked"?

If you sent it to HPT to unlock it why not use their software to calibrate?

If the TCM is a T87A then they are not supported by EFILive (note the T87A came out around early 2017).
