I need to see what is happening in order to diagnose a problem.
I have never had anything except a code reader in the past. My current problem isn't setting a code.

I was looking at these:

Thinking the Bluetooth one and get Tunerpro (or Tunerpro RT not sure if it matters) for my android phone.

Would you recommend this or something else? Thanks

Also found his stuff on Ebay.
Things like this are greek to me:

"GM OBDI data streams that use the 8192 Baud, Pin M protocol AND the 160 Baud, Pin E protocol. "
or
"Pin D & Pin E protocols "
"Your diagnostic software must be able to receive the data stream as 9600 baud. Instructions are included on how to implement this with TunerPro/TunerPro RT"

Found this one: Maybe this is the most robust , best deal , so I can use it on later model OBD2 cars too...?

16 Pin and 12 Pin ALDL OBD1 Bluetooth / Code Reader/ Scanner / Adapter Combo

The second one you posted is still for OBD1 only, so will not work on cars newer than about '96. Around '95, GM switched the OBD1 port to use an OBDII style port, but kept the OBD1 computer. You would only need this model if you are going to work on something like an LT1, or a Series I 3800 from a '95 car.

I've used the Tuner Pro a lot, and really like it. You can monitor while driving ( use the RT version), and do data logging. You can also use it to modify the programming ( with an add on chip burner). I used it with a plug in cable, rather than bluetooth. It's just as easy, since you have to pull the bluetooth adapter when you are not using it anyway ( pulls power!- will run down a battery).

Set up can be a little confusing at first, but once you have it set, it's done. There used to be a tutorial on RedDevil's website on how to set up the tunerpro. If it's not there, others, including me, will be willing to help.

You need basic data acquisition. I wouldn't complicate the matter with fancy equipment. The cheapest thing that gives you the ability to read your sensor values at the trouble spot unless you see lots of diagnostic work in your future. Check out Moates.net as an ALDL link and Tunerpro should be more than enough to get the info you need from the ECM. I had this problem with a bad MAP sensor. It never set a code apparently because it was stuck at a MAP value (~60 kPa) that was within the normal range of the expected signal most of the time while driven and couldn't meet the conditions long enough that were necessary to set a code. Looking at the data and seeing that the MAP value never changed made it easy to identify.

Ok thanks , so the Bluetooth may be over complicating it.

If I go with a cord, how about one for android? Or would I need to use a laptop, maybe there is an advantage?

You may be stuck having to switch back and forth to use your phone. Simply because the bluetooth devices have the OBD connector attached to it directly with no option to hook through USB. Unless you find one with a USB spot as well.

I have a ELM bluethooth reader hooked to my Sonata and never unplug it. Have not run into any issues with it. However I am not sure if the newer cars are wired different because I know mine is not powered up as long as the ignition is turned off.

If you're trying to locate a potentially difficult problem source you need to be able to look over a lot of data, as well as even graph it and for that you need the comfort of a good size screen and storage device. Laptop for troubleshooting and data analysis, phone for just looking at sensor readings for the heck of it.

I bought the BT version one from that ebay seller couple years back. Didn't work for my ECU for some reason. The seller was really nice, tried to help me figure what the problem was but could figure. In the end the seller refunded all the money included shipping.

I would just by an OTC scanner from the day. Do not overcomplicate things. I was trained on these computers back in the day and they are very, very simple to work on. A good OTC 4000e will be super inexpensive and tell you everything the car can say. Here is one on ebay for $80 (best offer) with free shipping.

These come in a suitcase sized case, so that is the only drawback. Otherwise it is perfect. I happened to have bought one at an estate sale last week for $20, so I do not need to watch this one anymore on ebay.

So probly just this and a laptop.
Comes with software, which must be similar to a homebrew of TunerPro....?

Probably comes with Tunerpro. Tunerpro is Free to all. Tunerpro RT has a "donation" request, should you like the software enough to donate after using it. The cable you posted is being sold by Reddevilriver, which is the site I posted above. Might get a better price buying direct ($55)- it saves the seller the ebay fees??
