Truck in sig, running extreme street. Had my ARP studs put in by the dealer, then had the truck puking again. At first it only puked once on the way home and I wrote it off to overfilling the coolant, since it didn't do it again after that. Well gradually it has come back and just as bad as before. I do still have my EGR cooler in place. I finally got a chance to datalog the truck last night (after extensive experimenting with Windows Vista and the SCT software.... AHHHHH) and took her for a spin.
First let me start by saying I can NOT believe how many parameters you can keep track of with the SCT software. Watching everying happen on the laptop in a graph was awesome! There is almost too much to record! You could burn a whole tank of fuel and not even touch half of the stuff on the livelink software. Once you're done everything can get exported to an excel file. Which my buddy did for me, but for some reason he doesn't know how to put the file onto my thumb drive plugged directly into his computer hehe
Anyways I was told to check out coolant temp VS. oil temp, as my oil cooler could be plugged. I dont have the data on me, but the rough numbers were as follows:
Oil temp and coolant temp were within 12 degrees of each other on the nose, like suggested.
Driving down the road:
Oil temp dropped to about 140-145, and coolant was 174-178 at a constant ~60mph.
I'm not sure what this means but I recall reading that the oil and coolant should be around 12 degrees difference or less.
What does this mean? Is there anything else I should check with the datalogging?
*ALSO - you may want to have a buddy in the truck to run the laptop cause it can be realllly
distracting. I had my buddy picking parameters out for me and reading numbers off*
