We clarify the higher-dimensional origin of a class of dyonic gaugings of D=4 \cal N=8 supergravity recently discovered, when the gauge group is chosen to be ISO(7). This dyonically-gauged maximal supergravity arises from consistent truncation of massive IIA supergravity on S6, and its magnetic coupling constant descends directly from the Romans mass. The critical points of the supergravity uplift to new AdS4 massive type IIA vacua. We identify the corresponding CFT3 duals as super-Chern-Simons-matter theories with simple gauge group SU(N), with level k given by the Romans mass. In particular, we find a critical point that uplifts to the first explicit \cal N=2 AdS4 massive IIA background. We compute its free energy and that of the candidate dual Chern-Simons theory by localisation to a solvable matrix model, and find perfect agreement. This provides the first AdS4/CFT3 precision match in massive type IIA string theory.
