ok i've made/scanned a few tidbits of information some are just general information, some are more specialized.

an easier to read version of the obd1/2 diagrams posted on ht.

just browse through http://members.shaw.ca/cua0/ecu/
i'll most likely be updating this as i get more information.
if you have any requests let me know and i'll see what i can do (just general honda information for the most part is what i have access to)
