Rob;
Since I have a 12A Turbo Rotary, an copy of the shop manuals, and a friendly,
knowledgable mechanic, I will see if the signals you listed can be identified.
It might take a day or so.

A company by the name of RACING BEAT used to be in the Los Angles, California area.
These people were MAZDA performance specialists. They provided several modifications
that could be used on the EFI system. If they are still around and if you can
contact them, it might be quite useful. Try looking in US based auto magazines (Car
and Driver, Road and Track, etc.)
