crucial settings with respect to fvSchemes and fvSolution to achieve convergence

I am trying to do RANS of pulsating flow in a 2-D diffuser.
I use pimpleFoam solver and the settings are copied from pitzDaily case.
While giving uniform inlet velocity I have a converged solution with a very small deltaT.
However when I run a simulation with pulsating inflow the simulation diverges.
I am using kEpsilon with average y+ 22.
What are the most crucial settings with respect to
fvSchemes and fvSolution
to achieve convergence (for different solvers as well)?
