I have the ECU 18FD.5Z and key from the donor car (Punto 1.2 16v), but without the immobilizer box.On the other hand i got immobilizer box from another Punto and the key again.My question is - can i start the car with on of these combinations. I almost finished the wiring and it seems that only 1 wire is going between the immo box and the ECU(grey something).
The real question is - where is the CODE kept - in the box , in the ECU or the worst case - in both.
And another question - which wire from the Punto side to connect to which wire from the Cinq side to make the rev counter work ?
P.S. after i finish my swap and it fires, i will surely donate to this forum

The code is in both so you will need the corresponding code box for the ECU.

my bad... sure someone can virginise the ECU cheap still

Yeah , 8v only.I've just been told by a friend of mine that in the Punto Gt you can swap ECU's because the code is only kept in immo box and key, thus if i have an immo box and key that are mate together i can fire it.But this is on the Punto GT with Bosch ECU (of course with immo).He tried that several times cause he has a small garage where he is repairing only these cars.Why should be different on the 16v ECU as the it's immo box is the same with GT and Cinq one ? I've not tried this personaly so anyone
who not agree with this , just make me know
