Do you have documentation that you can share, specific to vehicles built after April 8, 2019, having revised phasers and new PCM calibration? And what exactly was calibrated in the PCM? I really hope this to be accurate, considering I have May 2019 build date!
If this is correct, and the cam phaser issue has been resolved for the vehicles built after April 8, 2019, is Ford installing the phasers with the updated design (part #) AND reflashing the PCM for vehicles coming in with phaser issues? It appears that some have had the phasers replaced twice, and continue to have problems.
If PCM calibration is truly part of the root cause, I wonder if the new factory calibration carries over to those with aftermarket tunes? It appears this would be a good way for Ford to easily deny cam phaser warranty claims for anyone with an aftermarket tune.
Not sure of this info. Folks getting fixed since that date are still reporting failures.
