Does anyone here disconnect their battery for long term storage? What about the KAM (keep alive memory) in the computer. Any issues or does it successfully relearn after a few minutes of driving? Thank you in advance.-Brad

 

Mine has been plugged into a Battery Tender for the past 3 years.

 

I did go that route with my Sunbeam Tiger at one time. As you probably know that car also has a trunk mount battery. The device probably overcharged the battery. That spring when I got in to start it the battery blew up in the trunk. Luckily it just blew the tops off rather than spew sulfuric acid all over. Still sounded like a shotgun going off close by. When I looked that problem up on the internet I found several instances of it occurring to people. It happens more often than one would think.-Brad

 

I have one of the master power shut-off lever switches that drag racers utilize.
Mounted it to a bracket near the battery in the trunk.
It won't work for official drag racing safety rules due to the location but I can use it to isolate the battery when the car sits for weeks at a time and it also makes a good anti-theft device.
Since mine is an LS1 conversion it doesn't answer your actual question on the Ford ECU.
