We study the relation between nuclear massive black holes and their host spheroid gravitational potential. Using high resolution AMR numerical simulations (using ENZO), we analyze how gas is transported in the nuclear (central kpc) regions of galaxies. We study the gas fueling onto the inner accretion disk (central pc) and the star formation in a massive nuclear disk like those generally found in proto-spheroids (ULIRGs, SCUBA Galaxies). These sub-pc resolution simulation of gas fueling that is mainly depleted by star formation naturally leads to the `M_BH - M_virial' relation, with a scatter much less than the observed one. We also found that the `M_BH - Sigma' relation is a byproduct of the `M_BH - M_virial' relation.
