In the latest update (which may still be beta) V8.3.35 it has a section where you can import TIS files for T87A TCM and E41 and E90 ECMs. From there it is supposed to take the data from the uploaded TIS folders and put them into an editable tune format. At that point it is my understanding that EFI Live can flash these files back after being edited and an E41,E90 unlocked. Anybody have any trial insight on this and the process you use? I don't have one personally to experiment with yet.
