If the autrionic's map/ignition trim is analogue typr, you can almost use the 00-5V flow sensor output to trim yout fuel or ignition automatically, this way - no water = no map change.
If the Autronic input is a digital type, you can use the DDS3's digital "map switch" output or the 2d's "digital " fault output" to switch to a less aggressive map.
You have a choice.

Changing the 2c to a 2d is not an option - I would have to add components to convert the 2c to the 2d. Comparing the two systems, it looks like 2d = 2c + FIA2 + Change-over Relay + 806-157 pressure switch (for MAP sensing) + 3A fuse...
