air fuel data log with x3

[KingBlack]

does the x3 need to be connected to a laptop to log a/f ratio or is this something it can pull off of the cars ecu?

I believe you can do some kind of datalogging on th device, but I haven't done it. I've always plugged it into a laptop and used Livelink. You'll need a wideband that you can plug into the X3 to datalog A/F.

Yeah, you need a wideband. The X3, or even a laptop wont do it without a wideband.
