Currently with my 04 f350, I use a SGII to view EOT,WT,TFT, and boost, currently the highest I've seen my EOT was around 215, WT around 195 to 200, TFT around 165, so I be conserned with these readings, or if I gets let's say around 220 is when I need to worry, I just replaced my air filter, tomorrow I'm cleaning the EGR valve.

 

Those numbers sound fine. You should worry when the spread between EOT and ect is consistently over 15 degrees at 65 mph, with the ECT at full operating temps, and flat ground. EOT being the higher of the two.

 

you need to compare ECT vs EOT temp deltas should be no mre thav 15* spread

at a steady 65mph after coolant and oiol reaches there high points take you deltas

 

I have looked for SGII, there is not setting for ECT for 6.0 or any of the Ford readings, within the next few weeks I'll be getting another reader/programmer, which I've checked and it says it reads ECT, the only thing close is EBP but that's in PSI not degrees

 

on SG ECT is actuly marked fWT thats your coolant temp its pre programmed = farenhight water temp

that SG will get alot just take some getting used to

 

Also ebp is exhaust back pressure. Witch is why its in psi.

 

Here are some more codes for your ScangaugeII, this are the Xgauges:
