Depends. If it's an A40, you have to be able to obtain a FULL read in order to do a full flash. A full read isn't possible with the regular software download, but can be done with a software patch IIRC. If it's an A50, you can do a full read fairly easily, but not sure on full flashing. The 6 speed TCM's are different from the 5 speeds.
On mine but no tuning data shows. Nothing will open. When I looked in the EFI Live forum for information about it I found that it wasn't available yet. That is for the LML A50 TCM. That's how I understood it anyways. LMM A 50 does have support.
