    That sucks. Everything I read on other forums said it did it all. GM is even using the tech2win software in combination with the MDI 2 for dealerships to work on vehicles prior to 06 since they've abandoned the Tech 2.

    Yeah. That does suck. How can that be though? What version of the software would they have copied that wouldn’t support the older vehicles? It’s probably not that simple since I don’t even computer, bro.

    Surprisingly I have received 2 emails from the seller on Amazon today.

    Here is my original email this morning:

    D45B200F-88DE-46F8-93DE-6D532EEB2D6A.png

    I received this response within about 10 minutes:

    EC9DEB13-6878-4712-99F0-63F2AFA62D79.png

    My response:

    B92E9A06-3F62-4F50-BE2B-9C75C419FDC6.jpeg

    Another email I received. I can’t tell if it was in response to my original email or the second email. We’ll see what they are able to find out. How would they know their customers are using it on older vehicles? I’m not super optimistic, but we’ll see.

    Just in case you don't know, WhatsApp is a phone app. Similar to snapchat.

    Oh thanks! They just asked for that again. So is it text or voice?

    I think both. Pretty much anything you can already do, just through a app. Yeah, makes a lot of sense, huh? Lol

    After you told me about this they told me the same thing. I’ll download the app tomorrow and start a conversation I guess. At least they acknowledge that they are from another country.

    Just remember that FaceCrook owns Whatsapp. And despite statements of no sharing of data between the two, well, just read the news about how likely that is given the reputation of excessive data mining and hiding disclosure from the consumer . . .

    Might want to check if the vendor uses either Viber or Whisper.

    Since I won’t have a computerized solution anytime soon I finally just went to a dirt road and did a ton of panic stops to make the abs cycle. I just bled the brakes and I finally have a good pedal. I think I’ll be changing my gear oil Saturday, so if I do, I’ll put the 1-3/16” wheel cylinders back in to give those another try.

    The tech2win is supposed to work on anything obd2, so 96+. It is a virtual tech 2 machine that allows the same software a tech 2 uses to run on a pc(32 bit windows 7 since the software is older).

    Drove the Tahoe on the highway for the first time since the gear change. I love it! No more gear noise and the lower rpm made a nice difference to engine noise. It still carries about 4psi at 75mph, but I do notice that it isn’t quite as snappy as before when you mash the pedal at that speed. No biggie. Once it spools it’s motorin’.

    The reason for the highway drive was to get the axle warm before draining the gear lube. There was just a little bit of metal on the magnet, but nothing to worry about since gears and bearings were all new. Just for funsies I decided to check the backlash and pattern now that the gears have 500 miles on them. The backlash is .007”, so that’s cool. The pattern was saying it needed a little more backlash, but since the gears are quiet I didn’t want to mess with it.

    While I was working on the truck I decided to put the 1-3/16” wheel cylinders back in the rear brakes. My initial impression was that the brakes were more responsive and the rear brakes could lock more easily. I continued to drive and test the brakes and after just a couple panic stops the front brakes were already fading badly and the pedal was soft. Not impressed. I’m going to keep driving it and evaluating, but I think I may end up either going back to the EBC pads or maybe try Hawk. Not sure yet..... I wish I had seen that a GMT800 swap was so easy and affordable before I invested in this setup. Hopefully I can make this setup work better and not waste the money I spent on the rotors, calipers and hoses - all things I would have to change out with an 800 swap.
