I done this a half a dozen times with the 1227165 tpi maf memcals. I have used moates d2 and aries low profile dips maybe the same thing, not sure. If I try to reprogram a uv eprom in the memcal/adapter I get some strange readings and it will not reprogram. Seems to work flawlessly once reprogramed outside the memcal and inserted. I do have to take the ridges out of the blue memcal cover to get it to snap on.
