I saw that as well but they gauge has the ability to display AFR ( i think) as well as Pyro, boost and other parameters. It has enough OBD stuff for our rigs, I'd think but who knows. Anyway, just trying to find a single gauge that does everything.
Oh then take a look at the PLM? Gauge. Or PLE or something like that. I have a link somewhere.
