  The understanding of heavy ion collisions and its quark-gluon plasma
formation requires a complicated interplay of rich physics in a wealth of
experimental data. In this work we compare for identified particles the
transverse momentum dependence of both the yields and the anisotropic flow
coefficients for both PbPb and $p$Pb collisions. We do this in a global model
fit including a free streaming prehydrodynamic phase with variable velocity
$v_\text{fs}$, thereby widening the scope of initial conditions. During the
hydrodynamic phase we vary three second order transport coefficients. The free
streaming velocity has a preference slightly below the speed of light. In this
extended model the bulk viscosity is small and even consistent with zero.
