Thoughts on Cobb or GIAC?

For the current generation of Cobb Accessport, once the tune/map is installed, does the unit have to remain connected in the vehicle or is that up to you?
Years ago I had a previous gen Cobb Accessport for a Subaru STi Limited, and once you installed the tune/map, the unit was disconnected and stored away.

From what I remember, it was around 15 minutes as it has to copy the existing file onto the Accessport first before flashing the new map. I strongly recommend you connect it to a battery charger and make sure you turn off the interior fans and radio during the process as if for some reason it dies during the process, you could brick your ECU. Contact Cobb if a plug into the wall charger like the CTEK one would suffice. You might as well have one of those on hand anyways.

I don't think they believe that the installation process will necessarily cause your battery to go dead. I think they recommend this simply because they want to avoid any possibility of a loss of power during the installation process. The installation process is fully dependent on the availability of a source of electricity and, if your battery is not fully charged, there is a possibility that there may not be sufficient power to complete the installation.
Any loss of power during the process would probably result in the corruption of the ECM due to the loss of the saved image of the ECM and the failure to install the Cobb program in place of it resulting in the need to replace both the ECM and the Accessport device, neither of which I believe is covered by Accessport's warranty if the cause was your failure to take proper care to insure that your battery was fully charged and placed on a battery charger during the installation as recommended.
