Question about the ECU?
My car sits in the garage , sometimes for a week maybe two before i start it or drive it . So here is the question ,If the battery gose dead and can't start the car! To what point will the ECU reset or in my case there is still a little bit of juice but not enough to start the car?( basicly a dead battery) Is the ECU still working or will it reset? Is this bad on the ECU or should I disconnect the battery when my car sits?

If the battery goes completely dead, the ECU will reset. Its not a problem for the ECU. It will relearn the optimizations when you start driving the car again. Takes a few gas tanks.

ECU cutoff.
The battery would have to have, no sign of life at all, to cause the ECU to clear. No dash lights, no nothing. It only takes the smallest current to keep the ECU memory up.
My car can spend a couple of weeks in the garage, without the battery going low, may be your battery is 'past the use by date' , or you may have a leak in the electrical system. Harvey.

It won't hurt to just let it sit overnight with the battery disconnected.
