I'm sorry to hear that the problem is not resolved yet.
Has the dealer hooked up a water pressure gauge and monitored the pressures at various rpm and compare to the service literature?
Did your dealer do the "clear hose on the EMM" procedure to determine if aerated water was getting into the cooling system?
The EMM report showed within a 3 hour period that the engine temp sensors, air temp sensor, throttle sensor, and oil pressure sensor showed alarms. That is very unusual to happen to unrelated sensors in such a short period of time. The common denominator is the 5 volt sensor power circuitry. It may be a good idea to have the tech monitor the sensor voltage while the motor is operating at all speeds.

If the analog supply was being pulled down enough to be affecting peripheral sensor readings, I would usually expect to fide code 78 as well. Not shown here.
The 2 minute history clearly shows the engine cooling down from a fairly warm condition. As the overheat is described as happening only in certain RPM range, wouldn't one suspect poor inlet water condition? Aeration, etc.?
I really don't know what to make of the oil pressure sender faults at this point.
If you can get the data from the dealer, post what the water pressures are at idle and every 1000 rpm increment and at WOT. Also ask if a tech temporarily installed a clear hose at the EMM water cooling port and monitored for air bubbles at all rpm ranges, during turns, and at various trim settings.
