when it comes to piggy back systems, it does not really matter if ones better than the other but how well you can tune it,
my advice find someone who is skilled with tuning an e-manage and keep it.
but if you really want to get rid of it, i would think it is just plugged in via an adapter, so just un plug.
it should still run with the standard ecu but depends what has been done to engine.
if you want to know more try nissansilvia.com as there are a few good tunners on there.
