Using functional renormalization group, we show that while the system develops a nodeless anisotropic s+- order parameter in the moderately doped regime, gapping out the electron pockets at strong hole doping drives the system into a nodal cos (kx) cos (ky) d-wave superconducting state. This is in agreement with recent experimental evidence from measurements on KFe2As2 which see a nodal order parameter in the extreme doping regime.
