Where Did My Buzz Go?
The last week or so I have noticed no injector buzz on start up. Fresh Ford injectors (12k mi), FICM voltages look good. It's from Ed about the same time. Battery volts drops into low 11's during crank, initial idle bounces around 12, then up to 13.5 after a minute or so. No running or mileage issues. Just oddly quiet when flipping the key on. Starts right up as usuial. Just a little worried something is going haywire.

Since the fairly recent repairs, I got used to hearing it I guess. It just seems odd it would change like that. no running issues or anything. I'll try FORScan this weekend. Glad nobody said its a bad omen or anything lol.

My wife would say it ain't so good 
. I'm doing better than a lot of the guys I work with, a little ringing and moderate loss in one ear around 1khz. I do use my PPE a lot...now.

Rusty,
Do you think it's just too quiet to hear or have you confirmed it's not going through a buzz test? That does seem strange.

I've read of other cases where it would come and go, depends on temp perhaps?
I think the PCM commands it but the FICM delivers it?(obviously the FICM would deliver it)
I do know that with the FICM unplugged they won't buzz but that is not the issue here of course.
I think I also read it depends on the flash. Perhaps the flash or something was corrupted.

Most 6.0L programmers utilize changes to the ECM in order to achieve horsepower gains. However, ECM tuning is only part of the puzzle to restoring the performance and economy of the 6.0L Power Stroke. Ford's most current inductive heating strategy (which replaced the FICM damaging inductive heating strategy that was released in 2007/2008) resolves a number of cold start issues, but severely limits performance of the engine. With our standard ECONOMY FICM calibration, most customers see fuel economy gains as well as improved tip-in throttle response and better overall drivability from idle up through 3500 RPM. (We also eliminate that annoying injector post buzz.)

Post-buzz would be the after shutdown injector buzz.
Rusty I can't walk away from this smart assed comment.
If you really want to find your lost buzz you can move to
Washington, California or Colorado and get your buzz over
the counter nice and all legal like. The down side is the
Feds still frown on that.

. I could write a few paragraphs on the subject but the folks that gave me my security clearance would frown on that. Anyway, that was many years ago but good memories.If the buzz test changes (quiets down) at higher outside air temps that could be what's happening, it has an Atlas40 tune in it. It has been pretty hot here lately. Upper 70's°f some mornings at 05:00. I had planned to run an iniated test with FORScan today with my head under the hood but my laptop wouldn't cooperate. It hasn't been turned on for a month or so and it wanted to update but the drive was nearly full and then it hung on reboot. It's a Vista box and it still has the unmolested factory recovery partition but I have forgotten how to use it. It seem like I should have made a disk when I got the computer but I looked in the usuial places and couldn't find it. Hopefully I just hid it from myself. It may be time for a new (to me) garage laptop.
