you can get an MSD ignition if you want, some people feel that its not needed unless you're using for a high HP application.
anyhow to answer your original question, yes you can still use the MSD.
here's some products to look at:

the wiring diagrams can basically be found in the download section of each product...
for example this is for the 6A:

instructions start on page 21
also. with hondata, theres a couple different systems, s100, s200, and s300
even though the s200 is discontinued, it still uses the same romeditor as the s100 system
the s300 on the other hand uses SManager.
where are you getting the hondata installed? an authorized dealer should be able to put a basemap on it for you.
