Hello

Does anyone have data logged (charts, data in csv) from M37 or other Infiniti/Nissan 3.7 engine and can share?
I just would like to compare oxygen, MAF, short and long trims etc

Thanks

buy a cheap $15 obdII bluetooth scanner, and link it up to the OBD Fusion app. you can add basically any parameter you want to monitor including fuel trims. it will even calculate out your AFR or display in Lambda if you like.

what are you after here? not much you can do with the data without a way to correct trims anyway.
