my codes are only good for Ford PWM OBd2 ( my car is a 2001 )
TXD will be different for CAN bus
Yours should begin with
07E0 022 xxxx or something like that
RXF seems to be the same
There is a lot of trial & error in my case to get things right...
There is a thread (like this one) made for XGauge codes at: http://www.cleanmpg.com/forums/showthread.php?t=11742
It's more discussion than codes, though. If we need a discussion as a tangent of this thread, feel free to start a thread and I'll put the link to that thread here.
Now that the summary/info post is out of the way, here's some codes.
The manual gives you the formula and data for making trip data into XGauges so you can see trip data on the gauge screen. It's very easy to follow, but to make it easier, here's the list that I put together.
These are not vehicle-specific.
The first digit of RXF for all of these is: 8 (the rest of the digits to the right of the 8 are ignored)
The first digits of TXF, my description, and my label:
00 avg mpg current trip CA
01 avg mpg day DA
04 avg mpg tank TA
20 max fWT current CMW
21 max fWT day DMW
24 remaining gallons of fuel GAL
44 distance to empty MTE
64 time to empty TTE
Directly from the manual, horsepower:

GM VPW codes as tested on my 2002 GMC Sierra 5.3/4L60E. Some are imperfect and I hope to keep working on them, but they're useful enough to post. The PIDs I used were found mostly at http://www.hptuners.com/forum/showthread.php?p=1474 and I made the codes myself.
Transmission input and output shaft speeds. Looking at these two, you can determine your gear ratio (and therefore which gear you're in). Looking at ISS and engine RPM, you can determine your TCC slippage.
Problems: The last four characters in the MTH code, 0190, are the hexadecimal representation of the number 400, which has to be added to mine. I'm not sure why. By the time ISS or OSS read ~1000 they are accurate. At very low speeds they are not, and at a dead stop they read 400.
Torque Converter Slip Speed: I called it TCS, but TSS or TCC could work for you.
Problems: This code suffers from one bug: Negative slippage is displayed as 65535-abs(value)/10. So, -100 would be displayed as 6453.
Torque Converter PWM Duty Cycle: I called it TCP but TPD or TDC or TCC might work for you.
Problems: I don't think there are any.
Observations: When TCP is up, TCC slippage is up. I would have expected the opposite.
Problems: I don't think there are any. I have no way to confirm.
Observations: When TP is up, TCC slippage is down. I didn't realize that this pressure is used to adjust TCC slippage along with TCC PWM Duty Cycle. Is this the same pressure as is often called "Line Pressure" and controls how stiff the shifts are? That question is rhetorical here, I'll ask it elsewhere...
Ignition Voltage: IV -- this shows voltage of the ignition wire in the dash, not the spark plug wires.
Problems: I think it can be improved to show more accuracy. It seems to show whole numbers only.
