losing a tune
would having the battery disconnected for a week of so erase a tune on the car?

Not at all. What happens though is the PCM has to re-learn the best pararmeters for engine operation. Upon initial start up, after the battery has been disconnected, the idle will wander, it may run rough, it may even stall. The more it is run thought the better it will be.
