If you have an Android phone or tablet with Bluetooth, you can get the
Torque Pro app for $4.95
(There's a Lite free version, but that doesn't have fuel trim, IIRC.)
You'll also need the B/T adapter for the vehicle. I got mine from Amazon for

Here's the documentation on the app

vehicles I've used it on, a 2002 Escape and a 2014 Escape. I haven't gone

On eBay, or others, look for an ELM327 module. These are available in wifi
and bluetooth versions to talk to your apple or android device. I have the

try any of the apps that have free versions, then if you like it then pay
for the full version.
With the full version of the app and the module, you will have something
that gives live data for under 30-ish dollars.

graph, or as a dial. Depending on the data set, the display can be changed
to show the data appropriately.
