I recently picked up a 2006 F250 4x4 with a 6.0. I already have a scangauge from my Excursion. Last night I programed in the Engine oil temp and tranny temp Xgauges. Today I drove it 135 miles across Alligator Alley from Naples to Miami at about 75 mph.


The EOT stayed within 6-10 degrees above the coolant temp. most of the time, 8-9 degrees. The Coolant stayed between 186 to 190 and the EOT 194 to 198.


The tranny temp stayed a cool 154-155.


The only thing that was surprising was the Voltage. It would vary from 12.8-13.6 quite rapidly.


Givein these readings I would assume my oil cooler is in good shape.


Now that I have the Scangauge hooked up, what else should I monitor?

 

I am jealous, I wish my temp readings were that good!


I monitor my VSS (fan speed) when towing.

 

The main 4 I watch on the SG is EOT - ECT - FICM - ICP

Ocassionally I'll switch over to watch Boost - IPR - fan speed


Volts are always between .2-.5 lower at the OBD port (what you see on the SG) than at the battery. If you have a digital voltmeter, check the volts at battery and have someone see what they are on the SG. That way you'll see/know the difference.

Yes, your oil cooler looks good.

 

Thank you both! What is ICP?

 

Jnjector control pressure. You need at least 500 psi to fire the truck.

 

Ahh thanks!

 

I added FICM voltage which stays at a rock solid 49 volts. I also added the fuel injector control pressure. The lowest I have seen at idle is low 600s.

 

I look at Alternator , Battery, FICM (mp) at cold start Just to make sure things are up to snuff, running EOT,ECT, flipping around to ICP, IPR,BST and a few Other's when Towing then I throw a Towel over the dam thing so I quit worrying about it

 

SC2 reading of voltage is notoriously low and bouncy, so I use an external meter for that. I monitor ficm, ECT, EOT like every one else, and I usually have the final gauge on fuel level. It's very accurate, and actually corresponds very closely to the dash gauge, but it's easier to see. I have an external gauge for fuel pressure as well. I rarely monitor anything else, although I do have VGT set up, it was handy when my turbo unison ring seized up.
