I have an innovate wideband connected to my megasquirt and running into my laptop as well as an a/f gauge. really nice. You can program the outputs from the innovate and get it to simulate a NB gauge for hooking into the storebought gauges. I get a nice view of it direct into the megasquirt software and it also includes a program called logworks that datalogs the AFRs as well as anything else you decide to hook in.
