it states on the ultra gauge site that it can read boost but not oil psi. Nice looking tool for the $.
Would you mind giving the Amazon seller, or link to the listing? There are so many selling the "same" unit at various prices, AND Amazon pricing is not very stable, AND, reviews indicate that units from some sellers (apparently from different Chinese clone shops, or with different circuit boards) do not function as the others do.
I presume you paid the $5 for the full-featured Torque Pro app? I don't see one labeled Torque 2.
So, for $20, you have a serviceable scan gauge. Nice. I do see advantages of dedicated modules and output screens, but, for your use, and maybe my occasional use, this looks pretty cool.
