Would Tesla do the MCU1 to MCU2 upgrade on a Model S with a salvage title?

In theory, Tesla publicly states that any kind of DC charging is disabled for salvage/unsupported vehicles. In practice, I’ve seen only a few cases where more DC charging than SC was disabled. I don’t know about the US, but in the EU Tesla could run into trouble if they disabled CCS, for instance.
Third party DCFC was typically disabled on MS/MX vehicles. With the 3/Y left to use third party DCFC.

Some say this was due to how older Gen vehicles would handle the DC ‘flag’ in the config. Someone more educated than I could chime in on this.

Well, I know that in MS/MX you had to EXPLICITLY enable 3rd party DCFC with a flag. If you never enabled it (which comes down to you never bought the chademo charger), it was disabled right from the start, and nobody would enable it for you.

If the entries in the gateway changed and now it’s different, I don’t know.

I don't think that is true. People that didn't buy a CHAdeMO adapter often borrowed one and had no problems using it. (As well as using ones installed on chargers like EVgo does.)

As far as I know the only case where that was true was the original Model S 40/60s, where they didn't come with Supercharging enabled. At which point you had to pay to enable CHAdeMO and/or Supercharging.

fastcharge 0/1 disables/enables SC.
otherfastchargeallowed 0/1 disables/enables 3rd party DCFC.

As far as I know, except for those cars without SC enabled, all the others had fastcharge 1/otherfastchargeallowed 0.

You can see an example internal.dat here:
Lunars/tesla github

As I mentioned, this is how things were before. I don’t know if something changed during the last year, or how it is for the newest MS/MX.

As I said people have been borrowing and using CHAdeMO adapters for years, and they worked with no problem. So having other fast charging disabled was not standard for most Model S/Xs.
 
Not sure about this. I have seen many examples of people buying the chademo adapter and having problems with activation. I don’t know if the borrowers got in touch with the service center for this, or if they had previously used a chademo adapter, or if their car was used…

I would tend to think that otherfastcharge was disabled by default in most cases, but maybe not all. I’m really sure it was not enabled by default in a widespread manner. Maybe old vehicles had it enabled, and newer ones had it disabled. Maybe it depends on the year. I’m not sure, but most vehicles I had seen had otherfastcharge 0 and fastcharge 1 (unless they were salvage, then fastcharge was set to 0 with a log entry visible in the internal.dat).

It happened before I bought the car, but it "had" a base model 60, and the service center installed a new revision 90 which I was driving around on for a couple months after buying the car. Then they "fixed their mistake" and locked it to 60, so I'm now carting around 50% extra battery weight for zero benefit and the range is being held for ransom.

I wonder if you can pay ransom and how much? Similar to my SR
