@FordTechOne have you learned any new knowledge on what this PCM Re flash does and how it can prevent phaser issues? What if your truck has had the phasers replaced due to noise, or if your truck was built supposedly after the updated parts were being implemented in new builds. Does this flash still apply to your? Or does Ford still want to
Flash all these trucks to make sure they blanket cover everyone?

I’ve heard it changes the duty cycle of the phasers to reduce the locking/unlocking cycles that occur while driving in order to reduce wear. The new calibration applies to all models built up to 11/30/2019. The redesigned new phaser design went into production that same month. Trucks built after 11/30 would already have the newest part and latest calibration.

So 11/30/2019 and after trucks have the latest and maybe the only proven redesign of phaser parts. I gather the new calibration on those trucks will also further remove any future failures. With that said, apparently the new calibration doesn’t affect performance or economy.

I called 2 service departments , 1 said we r not flashing trucks unless they r making phaser noise ,which makes no sence ,I through it was to prevent phaser noise . another said they stoped doing it because of transmission shutters ,till I mentioned the new July 15th update , but said the notes say ,after flash dealer must drive truck 100 miles if shutter appears revert to old software .he also stated phaser noise is normal lol. also was positive ford has never revised the phasers ,because phaser noise is no big issue .

Well, those people have to work somewhere I suppose. I’m guessing the stealership felt bad for some homeless prius designers and hired them in this service department.

I’m hesitant to get the flash. I’m not having any noise and my truck drives great. I keep relearning the old lesson…if it ain’t broke, don’t fix it.

I just canceled my Thursday appt. I will just wait till next fluid change and worry about it.
