By matching Wilson twisted mass lattice QCD determinations of pseudoscalar meson masses to Wilson Chiral Perturbation Theory we determine the low-energy constants W-6', W-8' and their linear combination c(2). We explore the dependence of these low-energy constants on the choice of the lattice action and on the number of dynamical flavours.
