Trying not to be stubborn. I was taught that, not always correct and this is one of those times. Learn something new everyday! The idea behind OBDII was to standardize the connector, location of connector, using the same numbers for "generic" codes like misfires. This was to simplify. However states like CA & NY wanted vehicles OBDII compliant. This is because of cleaner emissions. More sensors can tell you more information and also will tell you when things aren't right, the CEL will be on. More parameters have to be met. The idea is lower emissions, fuel vapors not released into the atmosphere, etc. You may or may not have a OBDII Excursion. Depends what state it was sold in new. Sorry, my bad.

Yep, yours is indeed OBD I per that label.
Finally found my Mode 6 data for my 01 SD last evening using my Vehicle Explorer package from Alex Peper. No fault codes, but I had two cylinders with very elevated misfire percentage rates. New COPS should arrive tomorrow. Torque App is still unable to find any valid misfire data.

Good info here. 
The big take-away that I learned from this is that you can't count on the CEL to illuminate for misfires and other minor things that you would normally expect. I had a bad COP one day and the truck was shaking the entire way to work and back. I was waiting for the CEL to illuminate so I could scan it to find the bad cylinder, but it never happened. When I got home I scanned it anyway and found 2 codes stored that never set the CEL.
The other take away is that the PCM doesn't care if your cat is working or not because there's no downstream O2 sensor.

Probably wan to report it to the developer that it isn't working right. He is very responsive.

Sure enough, it was there. I pulled the same data as with the VE software. A pair of COPS are on order from Rockauto as we speak and should arrive tomorrow. High misfire percentages for Cylinders 1 & 6. At least they're super easy to reach!
That is true in some cases, but not always. The trucks at work that had coils go out never had a CEL, but mine did, and it was within a couple min after I knoticed the missfire by how it ran, and the sound of the exhaust.

After poking around Ian's forum, I found a reference that Ford's Mode $06 data was supposed to be in the "Test results" section of the app, rather than in the live or real time data where I had anticipated it would be.

just so im reading this right (as there appear to be two different camps here)
no ex sold in the US (that wasnt a cali truck) is obd2? they are all obd1?
how do the scangauges work? i thought those were all obd2 only?

I'll see if I can get some screen shots this evening...

Basically, only OBDII vehicles ("California") could be sold in the defined "green states". However, OBDII vehicles could be sold anywhere and may have been, depending on factory inventory and dealer orders. OBD I vehicles could only be sold into the non-"green states".
how do the scangauges work? i thought those were all obd2 only?
The Scanguage products communicate with any vehicle that uses OBDII hardware and communication protocols. The calibration level of the PCM isn't a consideration for the basic communications.

ok well thats clear as mud...i just spent the past 10minutes reading all those manuals and suppliments and im still not sure how to determine if my 04 ex 6.0 is obd1 or 2.
id just like to know if the torque app would work on my truck before buying it and the adapter.

to keep the adapter out of the way when driving. Also had to flip the OBD port over on the X so that the cable was going towards the passangers side

Sounds like it's been wrecked before you got it. With VIN, the dealer can get you a replacement emissions label.
