peugeot 106: swapping engine from 1.0 to 1.4

[mastaflex]

hello:
need your advises for a solution to a peugeot 106.
ECU has been swapped from 1.1 to 1.4. so now, engime managment was not adapted to the new engine (loss of power...). i think about flashing the flashing ECU with 1.4 dump.
but the problem, i don't have such file and and how to load it.
i think engine managment is on TMS374.

thanks to all

There are so many 1.0, 1.1 and 1.4 engines and the 106 has been build from 1991 till 2003.
Can you supply us with engine codes for the old and new engine as well as model years? Engine code can be found in the vin-number in position 6 thru 8 for newer cars.
Can you tell which engine ecu (name, type, number) is in your car?
Did you use the sensors/injectors from the old engine or the new engine?
Which wiring loom did you use?
