John / Barry,
Thank you both as usual, very informative and thanks for setting me straight on what I thought I would be getting if I were to upgrade anything to PS3. Glad I said what I said on current OEM state and learn what I will get with an upgrade.
Still going to do my PS1 engines soon as materials become available. My two DD40AX need to go DCS. Based on your comments I too see absolutely no reason to upgrade a PS2 to PS3 except for failure of components.
Good to know the real difference in the TIU versions also thanks, I was an early adopter way back so I have the original version still. No problems with it, but still good to know.
Thanks guys!
Mark
