MEFI 1 or 2

Hello again

I am trying to get a ecu i have re flashed with correct calibration to my boat,

Now I thought the system I have is a MEFI 1 ,
however I am being advised that due to the casting number on my TBI (17097230) it is a high pressure fuel system 27-33 psi which is for a MEFI 2.

Larry @ Indmar has been a star in helping me with this, but I just want to clarify what is correct.
