Multiecuscan Proxy Alignment help appreciated

[mpturner1979]

Hi everyone, hoping someone can offer me some advice,
I’m a complete newby to this software, so apologies if this is Multiecuscan 101, I’ve looked through previous posts, but couldn’t find an answer.
I have an Alfa Romeo Brera 2.4 and just had to replace the steering lock ECU. Before I can start the car I need to perform a proxy alignment, so I’ve just purchased the registered version of Multiecuscan on my iPhone in order to do this. My question is, could someone point me to exactly what WiFi OBD2 reader I need to perform the proxi alignment? I purchased one on Amazon which connected to do basic functions, but when I tried to connect to the ECU I got the error message attached. I understand there is a fox for these cheap units, but I’ve returned it now, and would prefer to just buy one that works out of the box if possible?
Any advice appreciated
Thanks
Martin[
