Keep in mind the ECU does a self-check/calibration on basically all the engine servos (throttle bodies and VVEL actuators) about 2-3 seconds after you shut the engine down. You'll hear

Keep in mind the ECU does a self-check/calibration on basically all the engine servos (throttle bodies and VVEL actuators) about 2-3 seconds after you shut the engine down. You'll hear the Pulse Width Modulation frequency (the mid-frequency digital sound you can hear from the engine always while running), and some clicking/clunking as it runs them through their full range, and then quiet. I LOVE THIS PROCEDURE'S SOUND!!
