Hi guys,
New to LRs
Picking up a 2017 Discovery HSE 3.0 D5 on Thursday
Full service history, 85,000 one

Looking at a way to monitor and change things.

I have a Bluetooth OBD reader (good one, not cheap one) and have used that in my Ford Everest with Torque.
I assume that will work on my Disco to read values if needed.

Also, used to use an UltraGauge to monitor temperatures while towing. Their website doesn't give a lot of info for my Disco
Anyone using one on theirs? Get the info you need?
Or is there an alternate device with small screen I can use? Don't want to use phone as means removing from case everytime to mount it.

And have seen some stuff on Gap.
That I'm for my model? Or a bit limited?

Used to use Forscan on my Everest,cand it allowed you to make changes to computer (indicated flashes, smart charge on/off, etc)

Other devices that can do similar, or is Gap it?
