What would be saved in the ECU that resetting it would fix?

Resetting the ECU will return your adjusted timing back to stock setup. It's a good idea in case any of it was pulled, thus a loss in power. It is like a vehicle's safety defense mechanism.

I don't remember if Evo ECUs have a "safe mode" or not. Anyone clarify this?

the ecu remembers the codes that it has pulled until it is removed via a code scanner or if you reset the ecu. when reseting the ecu you also remove the short & long term fuel trims that the ecu has learned.

......... which means what? It seems like you stopped in the middle of explaining it or I am just not getting it. Can you elaborate on this a little bit more. Thanks

Ahh, good to see you put the stocker back on!!! A lot of people make the mistake of putting on a VTA with no tune and wonder where the power went... Do you still hear any strange noises or did that problem resove itself with the BOV?
