IAB activates at 4600RPM, the VTEC solenoid activates at 4900RPM. This is on the OBD1 p13 from 93-96 Prelude VTEC's.
On the OBDII ECU from the +97 Preludes, I believe the two solenoids activate a little bit later. VTEC is at 5200RPM, and I forgot exactly where IAB engagement is at. It should be around 4900RPM.
EDIT: Yup, it is 4900rpm.
