Question about diagnostics (realtime) screen?

[Tah]

2012 Chevy Tahoe LTZ 4wd 5.3.

Is there a diagnostic tool that I can tell what my car (engine, drivetrain anything) is doing in realtime as it’s running? Can I plug a screen into something (OBD port) and send that information to a screen (iPhone, IPad, TV, anything) to see realtime things happening?

Tech 2 bi-directional scanner will perform that function. You can view these items in real time while you are driving by simply watching the Tech 2's screen. If you want to do time-based analysis, you can hook up the Tech 2 to a PC and download the data and view on the PC.

Can I mount a small screen? I guess think android tablet to monitor diagnostics while driving. I know I said tv but that or a laptop might be a bit cumbersome.

IDATALINK MAESTRO RR & compatible headunit radio will give you real time data on the radio screen

or download EFI live and connect a obd tool and a laptop, tablet etc.

If my head unit which I spent a decent amount of money on isn’t compatible I’m not going to buy a new one but thanks for the idea. I’ll look up and see if what I have is compatible with IDATALINK MAESTRO RR.

Do you know what tablet might be compatible? A lot of those are PC based only and that might get a bit cumbersome driving.

Do you know what apps I might be able to use on my iPhone?

efi live is windows compatible, so any windows tablet or laptop
as for android app's torque or torque pro is one, just buy a bt obd adapter those can be had for as little as $20-30 online like a ELM.

what info exactly are you trying to view?

basis obd2 info, a 20$ Bluetooth dongle and some phone apps will do it.

if you want to deeper dive into other modules it's a little more expensive.

^^^^^x2^^^^^ It would be more helpful to know what type of real-time data you are thinking about monitoring.

Right. I do understand but it’s one of those I don’t know what I don’t know things. I’m not sure what information is available for me to monitor outside of what I can see on my display information scroll thru lcd screen. Mpg. Engine hours. Miles to go. Tire pressure. Etc. beyond that I’d like to see anything that’s available to see. I’m just not sure what my truck will show me.

well for example my truck has almost 30 different modules on the can bus network all talking to each other and all have live data that can be viewed by different scanners. you just can physically display all the live data just for the heck of it.

you're basically going to need to research what data will help you with whatever driving you're doing and go from there. what you need to access that data and if that scanner can be used to output to your preferred viewing device will decide what answers you get. Just one really won't cover everything.

for an example, I have a hybrid yukon.. and I like to see what the hybrid pack is doing from time to time while driving, so I have a found a bunch of pids to put into torque app on my phone to view it.



now while I'm loading the trailer, I like to view the psi in the rear shocks, i have the auto level option. so I don't get to much tongue weight on it and go over the rated max, but torque app I can't find the pids to add that display, so I have a different dongle and phone app to display that data quickly.

so the answer is, it all depends.
