Since I had them still in a box and the time, I installed Yella Terra roller rockers (1.8 ratio) this weekend. Reached out BB to see if an updated tune is warranted. I also started the research on purchasing a tech 2. Wow, a bit overwhelmed on the amount of data out there.

What kind of data are you talking about? I bought mine from Chinacardiags, I think it was. If you get the Tech 2 be sure to get the GM software 33.004.

I believe I read your earlier post and went to the chinacardiags and selected tech 2 and there are many options listed. Until I really dig through these option/versions not sure which way to go. It's a bit confusing actually.

Here's what I see on that web site. You have a choice of the same Tech 2 equipment, one with no case and a $74 shipping charge; the other is with a case and free shipping. Same device and connectors. In the graphic I was on the "Carton Pack."

When you pick the other two options, for your GM truck you'll want the GM English software (Version 33.004).

The "version" with/without the key is for the TIS2000 software that comes for a Windows XP computer. Get the free key, but you don't need it unless/until you use a computer with the Tech 2. Doing that is optional but you can program modules with the Tech 2 and a computer. The TIS2000 software for the computer has all of the calibrations for your 2002 and you don't need the online account (no $) to use it that way. It can be a bit finicky to configure a WinXP computer to program so you may never want to do that, but it can be done.

Hope that helps.

This is perfect. ThANK YOU!
Yeah... I didn't see the option for the case before I clicked buy now.

But, this cooler pack I already had on hand fit the Tech 2 perfectly. Plus it has comfortable shoulder straps to grab and go.
Soft padded inside, a little rigid to offer protection. I had one of these, so I did not end up getting the case.
I can leave the cable connected and coiled up, saving the main connector from constant wear and tear mounting/dismounting.

Chinacardiags shipped really fast, was DHL in less than a week. Scan tool was top quality and the little I have used it already, has paid for itself and saved me a tow home.20220314_071203.jpg

I have a long enough soft tool bag (18"?) that allows me to store everything and leave the main cable connected. I never use the CANdi module since my truck is earlier than when it's needed.

Tore into my rear hatch this afternoon and after working the existing actuator a few times, I've decided to not replace it yet and see what happens. It appears to be functioning again for the time being. I sprayed some silicone lubricant on the moving points/parts to see if that might help it from seizing up again. I have a spare part on standby if it goes t!ts up again.

After all the work I did on the AC including replacing the lines that go from the compressor to the rear unit I found the rear fan was intermittent. Upon inspection I saw there was a loose solder joint where the ground connects to the resistor pack. Soldered it up and then found the connector was melted so I replaced that. Now for the first time since I remember I have full rear AC. Yay! The dog loves it.

Did you pull the hatch plastics off to get to those parts? How'd you get the hatch open?
