Last Shift Time ( in seconds)
Torque Converter Efficiency (in percentage)
Transfer Case Ratio (in degrees - I see from 0.2 to 0.5 regularly)
Transmission Fluid Temperature (in degrees)
Slip Counter (number)
Intake Air Temp (in degrees)
Fuel Tank Capacity (in gallons)

Very happy with some of the transmission stuff, including the temp.

I'm with you Les, I have been unable to get anything to work in any other module. The transmission ones surprise me a bid, and the fact that there is a transfer case ratio says there is some communication there (albeit if its anything of substance remains to be seen).

On the Activate Components portion in Diagnostics, I have been able to turn the fuel pump on and off, and when I tried to trigger the ABS light, it would turn the Service Engine Light on and off.

I noticed that with the Transfer Case Module...surprising that it some TCCM functionality is in the Powertrain module, however again what the data actually points to is up for debate at this point. I plan to try some of the terminal apps this weekend when I can sit in there and work on it.

I think we are at that stage with these 2nd gen blazer/bravadas that we can get just enough cool data to wet our appetites and do a lot, but not enough to do EVERYTHING we want without more costly apps and options...course that's me just being greedy I suppose.

Only HP Tuners with it's proprietary interface will do the crank sensor learn, injector balance tests, control the transmission, turn things on/off, etc on the Blazer. They cost $8.95, $150, and $350 respectively.

I see if on Summit's site for $349 (can't get to the HP Tuner site as I am at work and its blocked - guess I should be working). I plan to keep my Bravada as long as possible as my father in law bought it new and I got it from him in 2011. I still have the original window sticker for it and its in great shape overall, but getting the normal bugs that would come up on a 15 year old vehicle with 270k on the clock.

The functionality of CGP and Torque Pro (have both) on the go is awesome for on the spot diagnostics, but I am not opposed to having that deeper level of functionality. Can it control the transfer case at all?

* Connect/GM Powertrain/Full Auto Scan/OBDII/select the shown address
* Let software scan the available PIDs
* Save PIDlist to a filename of your choice.

Now you don't have to be connected to the vehicle to do the rest so disconnect and go back into the house.

* Connect/GM Powertrain/no scan/import PIDs /import from file/select your PIDlistfilename

To make a CMP Retard gauge like mine

Select Dashboard

* go to a blank page
* tap in top right corner of the screen
* select add gauge
* select CMP Retard* from available PID list
* Check Digital
* Select Add

Then to make a misfire counter like mine

* select Misfire #1 from available PID list
* Select Add

Repeat last steps again for each of the other desired misfire counters

When done hit your back button on your phone and the Add gauge screen will disappear.

Press on a gauge you wish to move until Display config appears.

* select Drag and Move
* Drag the gauge to the position where you want the gauge on the screen.

Repeat until you have the gauges where you want them on the screen.

To save your profile, touch the top right of your screen, select Guage profile/save/tell it where to store it/type in a name/hit save.

Now you can select from multiple gauge profiles by name by touching the top right of the screen, selecting gauge profile, and recalling the file.
