The screen shots posted by @saratoga2011, would have been one of those "nuggets", as it appears Forscan is measuring oil pressure.
Now you have called that data into question. If you can provide "actual" support for your "almost guarantee" that the data is not as posted.....
(instead of an opinion) That would be a "real nugget" of value. The prevailing view on FTE is that oil pressure can't be monitored electronically.
Well, now we have a screen shot of oil pressure on the 7.3L and an opinion that it's an algorithm....Hmmm which is it?

Some people on this forum are amazing. Someone finds a way to get oil pressure on this 7.3 which doesn’t require an old school sensor and gets debated as to if its real or not. I appreciate the time and effort put in by saratoga2011 to figure this out and post his findings. It has long been questioned whether this cam and lifter issue is due to the variable oil pump or not and correct me If I am wrong but this is the first time someone has actually posted the oil pressure numbers. If you don’t believe Forscan and his findings then don’t read or go hook up an old school analog gauge yourself and come back with some data of your own. Forscan has proven to be very capable at many things so no clue why anyone would question the data. Ford has stated there is a way through programming to alter pressure, Forscan proved it works by disconnecting a wire. To me thats proof it is in fact reading pressure.

I owned a 6.0 and monitored PIDs religiously. That being said, I'm not convinced these are REAL readings and not a computer or algorithm projecting numbers. When you blow an IPR screen or a stand pipe O-ring on a 6.0 and get a crank no start the computer defaults to reading under 100psi or 1400psi oil pressure. That isn't an actual reading it is the computer telling whatever you are monitoring with what to display. Without a manual gauge hooked up I would be very skeptical of those being real world oil pressure numbers.

Where is the oil pressure sending unit switch located on a 2022 7.3?
I’d like to connect an electronic oil pressure sending unit and gauge to that same port. Sense the factory gauge is nothing more than an idiot light with a needle instead of a light bulb.

My 2024 7.3 built in kentucky Nov 2023 falls into this TSB. This past Sunday I did a road trip of 500 miles and during it had to stop to nap for 45 min. My wife stayed awake and after I woke up she said it would make a clunking sound once in a while. This must be related to the TSB right? I may idle it and stay awake to check it out soon. PIA. I have to take 1 hr naps during my work trips often.

Perhaps you shouldn’t just fall for the first bit of information posted in a flashy graph, and question if it’s actually real based on Ford’s history…

And some people are just as amazing to blindly believe a flashy graph and ignore 40 years of history.
Im not saying saratoga’s findings can’t be true, but I want a manual gauge to verify it before I will trust the data.
There’s a reason no aftermarket scan gauge (same data Forscan reads) can’t read oil pressure (Banks idash and such…)

IF - it turns out that the Forscan reading is "the real thing", it is not surprising that the gauge mfrs have not included it yet, but they will.....IMO

I doubt it. To many customers will not understand why it is lower at a warm idle and the service department is already full.
Now it is possible ford could run a transducer to send pressure readings to the ecm and then just trigger the dash gauge to read good at say 12.5 psi. But I highly doubt you will ever see variable readings in the dash again.

I called my local dealer about a few other matters and asked about this CSP 24B27 update. They told me that my 23' F350 7.3 did not fall into the affected vehicle VIN list they searched.
I think it is important to point out this thought. What % of 7.3 engines need this CSP update compared to total installed built engines in these timeframes? Over a 15 month period (1/4/23 - 4/11/24) of production from two different assembly plants of USA affected Superduty vehicles; Plus, the affected Econoline vehicles span nearly 60 month's of production (5/30/19 - 4/11/24).
I do not know how many Superduty's and Econoline vehicles were produced over this period of time but the CSP 24B27 says affected vehicles are 36,170. This number has to be a very small amount of the total number of vehicles produced during these two different timeframes that are affected under this CSP notice. Remove the 5 years of production of the Econoline vehicles and how many of the Superduty's remain in the affected number totals?

Idle Time
I'm also wondering "if" your truck does fall into the effected lot, and when you bring your truck in to have this completed, will they pull the data for idle vs run time and if the idle time is very low, (as my truck would be) inform me
that due to the low idle time, the update is not required at this time.
Just a thought, not hat it would/could happen.
