Replace SID801A 5WS40155C-T - isp - 19-01-2022

Hi, Trying to return Peugeot partner 2006 to road.
Water damaged ecu SID 801a 5WS4040155C-T, HW9647423380, SW9657662380.
I have found a replacement with these numbers and transferred the original eeprom 93C56A and AM29F400BB which may or may not be okay, water damage was elsewhere on board, They could be read.
So... Cranks but no fire, everything electric works apart from wipers, headlights (flash okay), fan, clock and radio.
wrong mileage shown.
Codes are: 
P0603, injection ECU?
P0704, Cruise control (not fitted)?
P1613, I think this may be locked ECU?
Code reader is basic!
Next plan is to replace 93C56A code with an immo off as found on this site.
Any ideas, more info or better plan gratefully received...

All up and running, everything working I think. Fantastic. However displays wrong mileage. This is not as important as non working car but I would like to know why?
Is it possible that I loaded the original donor file back on to 29F400 (don't think so but it was late), if so and it runs without fault codes, do I need to change this (I have no idea what vehicle this ECU was for)?
I am guessing that the 93C56 handles the immobiliser and the 29F400 stores all other settings including mileage?
Any info to avoid pulling chip from board again would be great!
