Hi guys, I bought an immo off iaw 16f ecu for a Cinquecento 903cc in order to install it in my Cinquecento 903cc wich has a iaw 6f. The problem is that the car won't start with the new ECU.
Does someone know if I have to modify the wiring?
Could someone please post a pinout/scheme for the 16f and 6f?
Thanks
 
Old topic I know but there is a good chance the coils are reversed, the pinout for each coil is switched on some models 1+4 gets swapped with 2+3.

If swapping ecu leaves the car not working try switching the two pin coil plugs (or switch the HT leads round)
