Default Silly question: will disconnecting batt affect stg 2 map?

Just thought I'd ask so I can budget time:

I used openecu and tactrix to flash my 02 wrx to cobb stg2 map. I may need to disconnect the negative battery terminal for a few minutes tomorrow. Will I need to reflash the ECU or do Vishnu Reset trick, or will it be fine?

Thanks all

The Vishnu trick will speed up the relearning features of your ECU, but isn't needed. Your car will do that fine on its own after a day or two.
