Old thread. If you google there will be parts lists to do this. There used to be kits you could buy. I am not sure they make them anymore. With MM it may be an option if parts are hard to get.

MY EFI to Carb converted bike, with a customised loom being made by me... has an ECU part Number 32478-99 A. That's right an 'A'...
As I make the ignition loom/harness for this part of my build, is this ECU, the 'A', of 32478-99, able to work via a carb system?
I guess so because your ignition curve is for an 88CI Twin Cam motor...is set for injection and your carb is COPYING your injectors. Its possible to fit this OEM to a motor from Twin cam 88CI.
I can swap things, like the DYNO tech adjustable ECM, same Deutsch connectors, but tuneable 'within the range' for a re-jugged motor...

hard to understand your post. in the first paragraph you're asking a question, in the second paragraph it looks like you're answering the question.
to answer the question: yes, that ignition box works with the carb bike, or the conversion to carb from mm efi. >" ECU part Number 32478-99 A. That's right an 'A'..."<
