I wasn't able to find the answer to my question, so here goes...

If a piggyback or stand alone em is installed then the engine is performance-tuned, will the performance tune be "un-tuned" if the battery is disconnected for a length of time?

It shouldn't be, but that depends on the EM. Most EM's store the tuning in a ROM (think I got that right) which doesn't go away when power is cut.

Right, I've never had to change my settings because of disconnecting the battery.

OK, thanks guys! That's what I was thinking but I wanted confirmation on it.

Josh was looking for NVRAM, which is writeable, but Non Volatile, so it doesn't get reset when power is removed.
