I just installed the MM3 with DRD tunes I have 3 questions.
I installed the egt probe do I need to calibrate the sensor?
How do I show what gear I’m in?
How do you show the Percentage of the VGT?
I had the CT’s2 and this is vary new to me.

In the EGT PID I am also getting this.

I believe there is a certain order your have to plug everything in. Check out drd YouTube videos
I use the "Gear - Present" PID to show what gear I'm in, and the "TCC State right next to it to show what the converter is doing.
Is the TCC state the one that shows you 2 4 and 8?

Yes. 2=Locked 4=Partial Lock 8=Fluid Coupling
Is there a published list of all PID's available for the MM3 to monitor and possibly a definition of them? I'm looking to monitor my Transmission and i've got Transmission Pressure (TP) selected but i'm not sure if this is right. On a 120hp tune i get readings up to as high as 187. I've run the 150 tune and saw readings over 200 psi. It seems that this particular PID is tied to throttle %, gear changes, etc, but it's really hard to "watch" what's going on while driving. i've not been able to 'cause' it to read high (like moderate acceleration, etc), it just does under certain (yet to be determined) conditions. Normal at-speed, locked-gear driving the pressure reads right around 100psi.
A.) Does this reading even mean anything? B.) are these readings reasonable? I'm thinking of setting up my phone to record these gauges on slow-mo so I can see if there's any predictable correlation to other conditions.
Transmissions are still somewhat magical boxes for me. but i assume higher pressure is good to a point (meaning more pressure on clutch plates?) but too much will cause blow by, heating of the oil, or bubbling etc? but i could be on another planet. Yes, i know, the bottom line is stay off the 150hp tune until and unless i do some downstream mods.
Your EGT sensor is not correctly installed or you have exposed wiring touching the body somewhere. You need to revisit your installation of that sensor to correct the fault of Short to Ground.
Gear-Present will show your current gear as stated above.
VGT Turbo Position will show your VGT percentage.
1. https://www.igotacummins.com/threads/13052-MM3-PIDS
2. Transmission pressure absolutely matters and is tied to throttle position inherently because MLP (main line pressure) increases as RPMs/load increase, at least initially. Pressure goes down as load decreases.
3. At WOT on a stock valvebody you should see a maximum of 180psi; if you are running an aftermarket valvebody/transmission, 200+ is normal. 165 is the OE max.
4. You can influence a high reading by giving the transmission max load....i.e. Full throttle from a dead stop, power braking, etc.
5. Higher pressure is a great thing. Higher pressures ensure less clutch slippage and a better/stronger lock on the clutch packs.
All in I dailyed a 120HP tune from Ray for a long time. Had it not been for my transmission being stupid and not wanting to play nice, I never would've had an issue. But my truck didn't want to play nice.
i had to get a new egt probe even when it was out it was not reading right, I contacted mm3 and they sent me a new one, and it’s working good know that I got the calibration figured out, mm3 told me to put it at ambient temp but it just didn’t seem to read right so I tried it at 0 and it seems to be good, could you tell me what your calibration number is.

Ah so the sensor was faulted internally then, most likely. I can't speak to calibration numbers as I never had an EGT gauge on my 4th gen. However, I'm sure some others can chime in on that front.
