I think the 1994-1995 Del Sol VTECS were OBD-1 w/ a p30 ECU(http://www.hondaswap.com/reference/index.php?mode=ecu)/, is this correct? Do you think it would fix my problem as well?

You said use an OBD-2 from a 1996-1997 Del Sol or 99-00 SI, dont you mean use an OBD-1 because in your helms, the OBD-1 DIDN'T have an CKF?
