Works great with my diesel truck

I use this when towing with my 7.3 ford excursion. It connects with a wifi elm obd2 adapter I bought for under $15 on Amazon and I added the ford package
I now have accurate gauges for boost, transmission temperature, oil temperature, exhaust back pressure, and fuel rail pressure.

It would be nice if it worked with Bluetooth adapters but that is an iOS limitation not the software
