@gi1gamesh, @Capp777 and @CoreyMS I deleted the DPF/EGR on my 2011 6.7L and have been trying to make that factory sensor work in the exhaust block-off plate. I found this thread and have been reading about the formula you came up with. I put that formula in and pointed to the 22055e pid and it works (as in, shows numbers), but I’m not quite sure about the accuracy. Sitting at a stoplight I’m showing less than 200°F. the highest I get on my 15 min drive home is like 350°F @ 65mph on the frwy6 (~65°F air temp). I know removing the DPF/EGR reduces temps, but that seems like a lot. Does that seem consistent with what you guys are seeing? And does that seem accurate? I can see all the hard work that went into that formula (especially since I know what it took for me to even get to this point trying to figure it out for myself), so I really appreciate the time you spent on it. You are rockstars!

gi1gamesh: Long time no hear!!

Guy over on the Ford forum also wondering about the equation on this PID. He said that the temperature is showing 15000.

@gi1gamesh – are you monitoring EGTs some other way now, or just not monitoring them at all?

@MPD56 – That guy on the other forum must have the equation wrong. It worked for me on two different phones with two different adapters.

@piemmm – I didn’t try to go through and balance the parenthesis on paper, but when the app compiles the equation the last operation is = 35.67 + 330.59 – 237.33. Is that wrong, should we be getting some other operation at the very end?

Hopefully you guys can see the charts ok. Looks like the EGT calculation is working well and it also looks like the new turbo is keeping things cooler.

OK, I had some time Sunday to do some scientific testing. I did three different tests with three different tunes…Tow, Street and Race.

1) I kind of tried to replicate the runs you did on the graphs you posted Saturday. (Except, did you run it up to 120MPH!? or is that showing KPH on your graph?) I went from a stop up to ~30MPH under moderate acceleration on the on-ramp then up to 90MPH at WOT. I logged EGT, RPM and Speed.
Here are some charts of the logs.

Race Tune: https://www.amazon.com/photos/all/gallery/btg1danXRfqlSghXJ0smPA

2)Second, I set the cruise at 65MPH on a flat stretch and the EGTs settled at 350°F for all three tunes.

3)And last, sitting at idle in Neutral after every run the EGTs settled to about 150°F for all three tunes.

The highest temps I saw were just north of 800°F, nowhere near the 1400°F you maxed out at. After you came back down to a stop you settle just below 400°F, I am @ 150°F.

You know what…I think you may be right. I’ve been so flustered making sure I got that complex equation exactly right that it didn’t even occur to me that the units might be wrong. Usually I put °C in the UNITS field and Torque makes the conversion, but now that I think about it I may have left that blank, so it wouldn’t know to convert it. Osh, idiot!

Those look like what I’d expect. It would be awesome if we could find someone with a pyrometer installed in EGR blockoff location in a 2011 – 2015 Ford 6.7 Powerstroke truck to record their findings for comparison sake. My truck wouldn’t be so great for comparison any longer because of the new Turbo.

You said you’re running the SCT tuner, right? As far as I know that tuner doesn’t support any de-fueling. Right now the tuner has no idea what the EGT temperature is. SCT also sells a cable and a temp probe that’s made to hook up to the tuner. However, it’s my understanding that even with the probe installed it won’t de-fuel. It only alerts and displays the temp.

Last time I tried to find the range of this sensor I found it very difficult not to burn myself while trying to hold a torch and the temp gun targeting the sensor. Which happens to be a rather small target which fluctuates in temp quite rapidly. Whatever you do don’t touch the sensor after heating it with a torch.. (sounds obvious right?) Another thing to be mindful of is that you mount the sensor in a way that you won’t catch your truck on fire with the torch. I vote that ridesonsnow tries it this time. I’d probably stop around 1700 – 1800F. Propane torch is capable of 3600F. It should be easier to test now with the calculations already figured out there’s no need for the temp gun. Should be able to just turn the key on and have torque monitor the sensor while you heat it up.

I haven’t used torque for a while. I Just opened it today and my custom egt equation is all whacky now. Did something change in the equation parser?

Ian has renamed the predefined pids with

I don’t believe I’m using that?
