In this article we present the results of oscillation probability fits using Near Detector data at a Neutrino Factory. The method relies on the extraction of the beam flux at the Near Detector and using these data to predict the number of events observed at a Far Detector as a function of energy. Comparison with the observed events with the Far Detector can be used to extract the neutrino oscillation parameters. Error contour plots in the $\theta_{13}-\delta$ plane shall be extracted from the fits using "true" Monte Carlo data and also assuming realistic detector smearing for values of $\sin^2 2\theta_{13}$ and the CP phase $\delta$.
