I can't get it to show fuel pressure, haven't tried oil pressure. The PID's that are selectable aren't what I was hoping for. I do like that I can see IAT and Engine Coolant Temp but it's displayed in Celcius, which sucks. I have it set up to display Timing Advance, too but I have no clue what I'm looking at, LOL.
There are shit ton of PID's listed but only certain ones are available for display for the 3V. If I get time, I'll list them.
I had some issues getting it to connect initially but got it working. The adapter is kind of long and I have to watch I don't bump it with my leg.
So far, not worth $25 for the adapter and $5 for the app.
