My assumption would be that the O2 attentuation as well as fuel pressure adjustments would be lessened while the Methanol is flowing. There is less need for additional fuel from the DME.
If the flow stops and you are still under boost, O2 sensor attenuation and fuel pressure adjustment change to aid the DME into adding more fuel as well as retarding timing.
