I have a 2008 Subaru STi with a v2b accessport installed/married. I recently purchased a v3 accessport, but I cannot uninstall the v2b accessport to install the v3. When I try to uninstall, I keep getting the ECU Comms message about not being able to communicate with the vehicle. I tried following the directions on the screen about turning the ignition key to 'off' and then 'on' multiple times. I am able to switch maps and read errors codes with the v2b accessport, so the cable seems to be good. Any suggestions?
