I had a wifi ELM327 and DashCommand, but all I got for boost was a BOOST CALC value, that looked reasonable, but read the same on my ST as an SES, so I figure that couldn't be right. This was before the DashCommand update that added 2014 Fords to its database. Did you need to buy that to get accurate boost, or did I miss something? Thanks!Yes. I use my 4s without issue, best part is that the dyno/performance meter is seriously accurate for being a cheap app. You can see any codes that come up, the display will show boost, MPH, temps, I mean...everything. Best cheap 'mod' (not even) I have done to the car.
