Xantia Xu5Jp Ecu Swap

[tioklou 0]

Hello again. My car is a citroen xantia 1.6 (xu5jp engine) and i want to remap its ecu. i bought a second ecu from a same car to do the remap and to keep mine if anything goes wrong. but there are some differences between the two.

my ecu code numbers are: IAW 8P.13
16240.014
9619467680

the new ecu is: IAW 8P.13
16240.124
9621477380

Is there something i must worry about these differences before i connect it? what is your opinion? My car does not have a keypad immobiliser.

Thank you very much
