Isn't that what y'all use up there in Canada land

Yes it is BUT the ECT PID is in Fahrenheit and I can't change it... Or just don't know how.

Hey guys, don't wanna start a new thread but after lots and lots of searching I cant exactly find my answer so hoping someone can chime in here.
So my trucks been running awesome with the gearhead tuning and dpf delete, super pumped that it's finally done HOWEVER now that I can read my EOT and ECT deltas, they are kind of scaring me, they are exceeding 20 degrees C apart sometimes but I have no common signs, wrench light, power loss or anything that would lead me to think oil cooler failure (if I didn't have monitoring capabilities, I'd think it was fine).
Obviously I'm prepared for it to be an oil cooler issue as I'm sure that's what it will be, but I'm just wondering if anyone knew any other cases where EOT was high and it wasn't an oil cooler... Sensor? something else? Can the oil cooler fail without showing its failure?
Will doing the egr delete bring that EOT temp down?

Thanks so much.
