Where did he shoot? (let me know, I will get out my temp gun and see how it reads and compares for me)
Also, my Torque APP reads right with the SGII. That is the only comparison I have done.
What were the differences?
The SGII can only read what the PCM is reading.
And the oil temp sensor is right after the oil cooler. If he is taking the readings from some place else, like the oil pan, wouldn't he see different temps? Since the ump takes from the pan directly to the oil cooler, the pan will read higher
And as far as being in a "coolant pool", where better than the oil cooler?
So, the only place to shoot for comparison will be at the area of the sensor it's self.

The differences were usually about 10-15 degrees.
The oil in the cooler is always hotter than the coolant after the truck is fully warmed up, AND the idea is to exchange the heat from the hotter oil into the cooler coolant, then the temp is the oil cooler is not a good place to measure the temp of the coolant. I think.

Benny, you said cold soak temps should be 1-2* delta tops... I've got two 6.0 trucks now, and both are showing 3-4.5* deltas after 10-12 hour cold soak with ambient temps in low teens... Do I need to replace those, or just adjust my deltas while hot by a couple degrees? EOT is warmer in both after cold soak...
Hijack over... Sorry!

Thats getting to far apart
And it might not be Off Lineal it may be Multiple
I would just replace the Sensor thats Off sounds like EOT sensor

Since its my thread, I'll make it legit and join the hijack. How hard is it to swap sensors? Is it just an unplug, an unscrew, or are you pulling a probe all of the way out that will have oil or coolant dripping off the end? Also, are they expensive to replace? Can you get them at a parts store or straight from Ford? Let the hijack roll on!

If ECT and EOT is same temp right at startup within 10-15 seconds odds are sensors are Good and you need a New Oil Cooler
Guess I should read your other thread to get the Fill Picture here

Hopefully you have by now and his is unnecessary, but I just replaced it since it was getting studs anyway. The other reason I replaced it was that the delta was consistently running 12-14 at hwy speeds and thus I figured it was about time anyway. Those temps improved very little despite the new cooler, often getting to 11-13. It got worse last week when the coolant level dropped due to the degas bottle hole. I'm about to leave to find out what it will do now.

One thing to also consider when looking at temp gun readings vs temp probe readings is the probe is actually in the fluid where the temp gun is reading the material between the actual liquid and the gun itself and some energy has already been given up through heat tranfer. If this has already been pointed out in this thread i apologize and will learn to read better
