Ferrari Mailing List: fuel mixture analysis

[Michel Savard (mysavard]

1981 308 GTSi: I had a fuel mixture done on my car and the mechanic even printed a report of it from his little machine. I took it and left without asking him what this was all about. Can anybody explain what this should tell me about my fuel mixture ?
