Does your V6 have the code system/immobiliser.... If so you need the yellow code box, paired ECU, a matching key, and ignition barrel plus any locks you want to match. Of course you could just plug in an ECU from a pre-code v6 155, depends if you have/want to keep the code system?
Pretty sure you can't get a plug and play programmable one for the Motronic 1.7 - you'd have to junk the whole system and go with something like and Emerald M3DK which I'd imagine would be a fun wiring exercise before you start trying to get the thing running !
I may have an ECU/Codebox ignition barrel and one key it's just not available yet as part of it's in the car I'm driving and part of it's in the one I'm breaking so that depends how urgent it is. AforAlfa might be able to help with a non-code ECU as I also have one of those I borrowed from him but I'm not sure if he'd want to sell it as it's possibly part of his diagnostic kit..... or rgwm may be able to help....or stick a wanted post on alfa155.org as there's one or two there who may be breaking V6's??
