The big ones that we normally look at are in the charts below. These boxes are from the new PID Charting Tool that is just about ready for public release. I have to finish up the instructions now since BWST has finished designing the tool.
When you are selecting your live data gauges, you will see that some of the PID's have more than one selection. For example, Exhaust Back Pressure, you want to select "EBP_A". If you find that a PID is acting strange and there is another PID in the list for it, select them both or the other and see which is acting as it should.
Just because these are the PID's we often look at or for, doesn't mean you need to watch these. FORScan has the ability to save gauge profiles, so you can save multiple gauge sets for different uses and simply load the gauge set you desire to observe.
Instructions on how to use FORScan and FORScan Lite are in the 7.3L PSD Tech Folder toward the bottom.
Here is a recent gauge set profile that I logged data on recently.
You can change the color of the labels in the gauge and the size, but that is about it. FORScan does not have the aesthetic features like TP, but it is far more reliable and powerful than TP ever will be.

thanks Sous, I am having issues under load and need to see what’s failing may drop the tank later today to clean the screens!
and yes I know everyone is going to say just do the hutch mod , I’m not sure if it’s the only issue , as I accelerate truck starts bucking like it’s starving for fuel or oil.
already had my transmission guy by to look at it , he said I didn’t believe it was the issue, Which is a good thing ,so off to look at other things
You can check the fuel pressure for a few bucks, the SSJ method is in the Tech Folder.
You can disconnect the inlet fuel line to the pump, remove the fuel cap and push about 15 PSI of compressed air into the tank to try and clear the blockage, if there is one.
Oil level, check it.
There are various things you can watch in FORScan that might help you come to a decision point, but I would check the easy stuff first.

i was able to see my ipr and icp in forscan live data ipr is all over the place while under load! You can see the line gets all squiggly! Might be why I get an icp code from time to time generally under accelerating
If its convenient, start saving those logs when the IPR gets squiggly - would be great to put the forum's eyes on it and learn from it together. Whenever you are looking at live data in Forscan - it's capturing it in a log. You just need to remember to save it when you stop, before you shut the app down.
I usually pick "Save" so I can have the Forscan file for later review on my phone, and also "Send CSV" which let's me email the log, so I can pull it up on my laptop from my email account, and graph it in the PID charting tool. We'll graph it for you if you just want to post the CSV file.

i did not get that option when i tried to save the file, i also don't get the gauge option like sous has on his , not doing something right i suppose
Also not letting me replay the file , defiantly doing something wrong!
It looks like ICP is the squiggly trace. IPR% is pretty steady, though a few percent higher than normal on the WOT run. Likely trying to offset that unsteady ICP. It would make sense that you would get P1211 or something like it from time to time.
Can you do this same drive with the ICP unplugged, and see how it runs?
Does the ICP have oil in it? Is it original?
When you get ready to log again, go to your PID selection screen and change your ICP units from "kPa" to "PSI". I did it manually in the data file so I could plot it in the charting tool.
Check the names of the PIDs Sous shows above and pick one of those for your RPM and EOT, so they will show up automatically in the charting tool next time.
Having this log is great, Listor - thank you for posting it. The data is pointing to the ICP sensor, and we have a path forward to verify that.
Subscribed. I have Forscan now, but haven't really used it yet (other than once running the injector buzz test from my phone). I really need to learn how to chart this stuff. I'm sure it would help see how my truck is doing when towing. Just need to take the time to get it all figured out.
On a funny note, my wife asked me yesterday what I was doing on my computer and I told her I was messing with the Forscan app. She looked at me with the weirdest look and said "what the fk? You are talking to guys online about foreskin?".......LOL
Bucking and kicking with a squiggly ICP and solid IPR? I'm not sold that it's the sensor - this could be bad injector O-rings, a bad IPR, or something as simple as a missing tinnerman nut on the IPR. I'd start with the IPR because it's practically a free test.
Is the tinnerman nut on the IPR or in the valley?
Have a can of air (like for computers) ready. When it acts up, hold the can upside-down (this makes the can of air a freeze spray) and blast the IPR coil.

Oh Nice BWST , i couldn't make heads or tails from the numbers it saved, But yes i see the icp is an issue.
I did unplug the icp last night and made a short trip , I did not feel the bucking like before but it's pretty doggy without the icp and tuner both LOL
I will look at the pids again, and see what i can do

I have recently redone the injector o rings, ( that doesn't mean one didn't go south) Tinnerman is tight one of the 1st things I checked, it does the bucking right away only under load, warm or not, i can try the can of air anyway i suppose
also checked the hpop it was full , oil lvl is good too.
trying to go slow and steady so as not to over look the simple things!
Again thanks for everyone's help, this site and you all are priceless!
