A density functional theory is proposed for strongly interacting fermionswith arbitrary large negative scattering length. The functional has only twoparameters that are directly fixed to reproduce the universal properties ofunitary gas: the so-called "Bertsch parameter" $\xi_0$ and a parameter $\eta_e$related to the possible influence of the effective range $r_e$ at infinitescattering length $a$. Using most recent quantum Monte-Carlo (QMC) estimates ofthese two parameters, it is shown that the functional properly reproduces theexperimental measurements of interacting Fermi systems not only at unitaritybut also away from this limit over a wide range of $(ak_F)^{-1}$ values. Thefunctional is applied to obtain an expression of the Tan's contact parameterincluding the effect of $r_e$. Application is finally made to neutron matter.It is shown that most recent QMC results are well reproduced.
