Anyone have any Pros or Cons for a 123 ignition D-jet tune-4-r-v-p unit for 74 2.0 ?

This is how I programmed the 123 centrifugal curve on my '74 2.0, and it seems to work great:
I've experimented a bit with the MAP curve to add a little vacuum advance under load, but haven't figured it out yet, so for now am just running the centrifugal curve. Would be interested in hearing from anyone who is using the MAP curve successfully. |

That will give you a little more bite as you are getting off idle. Zach |
