Correct rotational behavior for O-C-C-O fragments requires SCEE=SCNB=1.0. This is in contrast to "standard" AMBER, in which it is normal to set SCEE=1.2 and SCNB=2.0. Unless you are attempting to generate rotamer populations, it is OK to use the "standard" values. Using non-standard values (SCEE=SCNB=1.0) may be unacceptable when a protein is also present.
