Resetting memory after battery disconnect

For the first time in three years of ownership, I've stored my CanyonStar for the last two months with the batteries disconnected (I've always been able to plug into shore power before). I know I'll have to reset my radio presets, but what other memories will be affected? Atwood LevelLegs? Others? Thanks in advance.

I take my batteries "Home" to charge during the winter and only rest the radio station memory.

In newer rigs, both the engine computer and the tranni computer may incorporate 'Adaptive Software'. This software learns as you drive and adapts the ratios of important parameters to achieve the best power and fuel economy. The tranni learns to adapt shift patterns to the engine. These setups are stored in short term memory.

When you disconnect the batteries for any length of time, the memory looses those settings. As I recall, 1/2 hour will reset them.

Built into these computers are some 'default' settings that the computers use when you reconnect the batteries. All you have to do to restore everything to the way it was, is to drive normally. A few hundred miles later, it's back to normal.

Depending on how you drive, and how far from norm the engines behavior is, you may not notice any difference at all. Or you might notice a slight improvement in performance over time.

This is probably the only other memory in your rig other then the radio settings.

Pretty cool if you ask me.

There is a possibility that you might have other adaptive software in other systems as it's getting much more popular with engineers. For instance, the way you set up the RV at a park can be incorporated into software for extending the slides in a certain order. Then push one button, and the adaptive software does it for you in the order you like, with the correct timing.
