"2000 Baja with efi 502's

"2000 Baja with efi 502's using the -3 engine controller. When engines are taken up to 5000 rpm the warning buzzer goes off (beep-beep, not steady) for the starboard engine. Checked for fault codes in ecm, nothing. Disconnected outdrive lube oil resivoir wires, connected direct reading oil pressure gauge to motor, 45 psi, water temp at 170 degs.
Warning will not stop until engine is shutoff, when re-started buzzer is off. I can also get the warning to sound off if I take only the stardboard engine up to 3500 rpm. Port engine at idle.
Any ideas?"
