I present new insights about accretion and ejection physics in low-mass X-ray binaries based on high-resolution Chandra HETGS studies of accretion disk winds in the microquasar GRS 1915+105. First, using 10 years of Chandra observations to probe the long-term connection between accretion disk winds and relativistic jets, I show how disk winds may actually be the mechanism by which stellar-mass black holes suppress their jets and regulate their accretion rates. Second, by performing the very first phase-resolved spectroscopy of strong variability in GRS 1915+105, I demonstrate that rapid changes in the broadband X-ray spectrum seen by RXTE on timescales of seconds are associated with measurable changes in X-ray absorption lines from the accretion disk wind seen by the Chandra HETGS. Furthermore, the mass loss rate in the wind may be as much as 25 times the mass accretion rate onto the black hole! I argue that the wind may be massive enough not only to quench the jet on long timescales, but also to produce or facilitate state transitions. Highlighting the immense dynamical influence of these winds on the accretion flow, I discuss open questions and new directions for Chandra in the study of outflows from accreting black holes.
