i can across this monitor that displays gauges and 1/4 mile times, etc. i was wondering if this is a good idea since i want a few gauges in my 2011 wrx sti and i dont completely like all the spots possible to put them, so a monitor that shows them would be a great idea in my opinion. also how is this thing mounted in my car? like a GPS to the windshield?

What gauges do you want or feel you need in your car? At the end of the day that's going to determine what you're going to have to do.

My understanding is that you would get a more accurate reading from a gauge or gauges that have sending units directly from what they're measuring. This Edge product would plug into the OBDII which may not be as accurate as you'd like. Have you looked at something like this 3-in-1 from Maddad

IMO SMY Clustermaker is you're best bet. Keeps your original gauge cluster in view and allows you to add 2 gauges. Then it'd be up to you to decide what 2 gauges are most important to you.

I hate to dig this up, but can you elaborate as to why OBD II logs are less accurate than gauges measuring directly from a sending unit? Is there some sort of loss of precision that happens when measuring through the OBD II port or are you trying to say the running through OBD II has a noticeable real time delay?

Well....I would say both. A gauge measuring something specific directly should produce a more accurate reading. It also will produce a reading in real time with quick sampling rates. It cuts out the middle man (in this case, the ECU) while it's measuring what it's supposed to. With OBD you're looking at measurements that are probably taken at a slower sample rate than what a specific gauge can report, thus the readings would be less accurate. We're talking about fractions of a second though so it may not be all that noticeable. Keep in mind though, that quality of the sending unit and quality of the electronics are the main factor. A cheap gauge more than likely won't do any better than OBD.
