oil temperature gauge

[OLdchuck]

Jim,
Thanks. after I sent the last post I was looking at the diagram and figured that it must attach with the 26mm bolt that attaches from under the filter housing. Is it tightened to any specific torque setting or do you just crank it up?

I was very disappointed that I couldn't even get the digital coolant temp going on my digital dash with FORScan (like I did with the 2018 F-150). And then no freaking oil (and transmission) temperature either. I'm in the process of finishing the job of installing the GT350 gauge pod with the oil temperature gauge, so hope at least somebody here can vouch for its accuracy when compared to a real gauge.It also has no numbers, but at least I should be able to tell if oil is hot enough to get on the throttle, and if it's getting high enough to get worried.

Have a related question: Do MT-82 D4 transmissions have a temperature sensor? The dash also doesn't have transmission temperature, but don't know if there's a sensor or not (saw a connector, but could be for R). Only has the differential one, which is the least needed IMO. And by the way, what's the normal temperature range for the Torsen? To at least know which range is desired. Thank you.

Mishsi told me 35 Ft/Lbs

I can't find the post but I do remember reading here that somebody ran a real temp gauge alongside the factory inferred one, and they were very very close in almost all conditions.

Would be interesting to see if someone with a GT compared an actual gauge like the autometer with the gauge reading in the digital dash to see how they compare in actual temp readings. Until that is done there is no way to tell the accuracy of the dash gauge.

Not the test you describe, but the center of the green zone is I believe 210F - I posted that info many moons ago someplace.

Anyway, when my oil temp on the dash was in the middle of the green zone, I checked the black oil pan temperature with an IR temperature gun and it read within 1 deg F. Just one data point, but told me the inferred gauge is pretty close.

As I mentioned above.

Just one data point, but told me the inferred gauge is pretty close.

I suspect you'd find the gauges diverge as the temps climb. One data point at nominal is nice but doesn't build a ton of confidence. In either case, I'm confident ford did plenty of testing such that the inferred oil temp erred on the conservative side.

One way to find out is go track the car and get the gauge needle steady at the top of the green zone (279F) and check it there. Yes, I'm sure Ford made it infer pretty close.

I'm sure the inferred temp is VERY close to the actual oil temp, for a unmodified oil system. The problem is when you make any changes to the system, such as adding an oil cooler. The calculation will not be able to reflect this.

SVOMk11, Do you know if you can tune the limp mode out and just beware or the temp?
If you have the increased cooling capacity then you would not want the limp mode when not needed.

Thanks for all the information on the Mishi.

I asked this very question to COBB. They said yes, you could deactivate the limp mode associated with the inferred oil temp, with a custom tune. The problem I have with that, is that I still have a fair amount of powertrain warranty left (probably close to two years). I would be concerned that any changes made to the stock tune could open the door for denying otherwise valid warranty claims.

Thanks, that is what I thought.
I think you are wise because given any reason they would deny a warranty claim.

Does anybody know which data the ECU is using to extrapolate the oil temperature? Would it matter if you change the oil viscosity, for instance? Just curious. Thx.

I have heard the following; coolant temp, cyl head temp, RPM, and oil pressure. If oil pressure is used, it's possible that oil viscosity may have at least some impact, by maintaining a bit higher pressure. I would assume that the ECU may see lower oil pressure, combined with higher temps in the other parameters, as a sign that oil temp is higher. Ford recommends 5w-50 when tracking the Ecoboost.
