Large neutron star masses as the recently measured $1.97\pm0.04$ M$_\odot$
for PSR J1614-2230 provide a valuable lower limit on the stiffness of the
equation of state of dense, nuclear and quark matter. Complementary, the
analysis of the elliptic flow in heavy ion collisions suggests an upper limit
on the EoS stiffness. We illustrate how this dichotomy permits to constrain
parameters of effective EoS models which otherwise could not be derived
unambiguously from first principles.
