Are there any options other than the expensive osiris software to do some logging? I'm not looking to flash the ecu, just do some logging for my own curiosity.

Long story short, I have a friend's g35 coupe for a little while and in driving it, it feels like it's gutless over 3500 rpm. It's the first one I've driven, but in looking at stock dyno graphs, the torque curve should be very flat across the rev band. Basically, nice low end torque, similar to my 2.5 turbo subaru, but power dies off above 3500 rpm.

I don't know too much about what mods are on it other than intake and catback. It still has the stock tune on it. I'm guessing there are no other options for logging, but it's worth a shot to ask.

 

I'll take the lack of responses to mean that there are no options...
