For those running efi, does cutting the battery power (negative terminal) affect any tuning the system has already stored/saved? I was wondering if winter storing of the car would negatively affect the efi system in any way.

Disconnecting the battery is no problem. Tunes are stored in non-volatile memory (flash memory).

Agreed. I was worried at first too, but it all still there.

Thanks for the replies. I figured this was the case but was not sure.
