i had a pretty same case before,just not finished the job due to some reason. It was honda freed 2012 with bad ECU. Some friends back then told me that if the ECU is replaced you need to sync it with the immo first before you can coding the key. It can be done with X431 or HDS..

the other solution for you can coding the key is to swap the ecu's eeprom (usually there are 2 eeproms that need to be replaced in there) from the old one to the new one. Just not sure if sync is still needed after the eeprom swap.

Hope that helps mate.. G'luck.

An i not register Micu (fuse box) first i have message in hds "Immo is not normal mode".

im right with u ana_11 , always when u try something u get this error "Immo is not normal mode" how fix it that the big question , but immo is in anormal mode because ecu and immobiliser dont have same synch bits into data for start car think that there are other trick or need reset sync bits and register then.
