Fla -Tn trip with the new 6.7! Logged about 420 mi today pulling our 5ver (appx 13800#). I am very impressed with the performance of this truck! Had 1 active regen about 3 mi into trip, soot% hit 100 the regen notice came on. Thanks mpd56, for all the pid's for torque pro! I was able to monitor the entire process. Active regen took about 9-10 mi and brought soot% down to about 8-9%. Egts 11&12 got up into the 1200+° range. For rest of trip egts stayed in 630-850° range with soot% staying between 26-52%. The only sort of let down for me was fuel mileage, its pretty much these same as my '09 6.4 at about 10.4 mpg towing @ 60-65mph. More info later

 

dually.. yeh.. not that much improved..
If the SRW's with 3.31's can do it, I'd like 3.31s on the dually too.

I don't need 30,000lb towing..

 

My '14 dually has 3.73 gear, same as my '09 6.4 did. Mpg may be the same, but that where the similarities end. Don't need near the throttle to get rig up to freeway speed. I'm sure the 6 spd trans has something to do with that. I'm well pleased with it so far! We've got another 300 or so miles to go tomorrow. Can't wait.

 

my 08 dually had the 4.10 rear.. like the 12's 3.73 better..

 

GW09F350:

Thanks for the report. Can you keep your eye on the DIA for me; mine never seems to go above 500 miles. I’m thinking it either subtracts miles (150?) or starts an Active Regen if soot is above 80%. Also I’m thinking I’m going to try and fine tune that Soot % equation, I think that the 100% is right and try to get the Soot % to read “zero” when the Active Regen shuts off.

Thanks again for the data.

 

Mpd, I'll do that. The DIA seems to update after each engine start. When I parked this afternoon I think it was reading in the 420mi range so it should hit 500mi shortly after we get started in the AM. As I said earlier, active regen started simultaneously with the soot% reaching 100%. Soot% still went up for a minute or so (111%) until egts got up to 800°+. When egts got over 1000°, the % really started dropping pretty quick but never got below 8-9%. Active regen only lasted 8-10mi. Will post tomorrow evening, hopefully from our destination. I can't get over how smooth and powerful this new powertrain package is! I love it!

 

Clarification, my DIA (on torque pro) doesn't seem to be an active display (running total). The mileage reading only updates after I shut the engine off and restart. Don't know if that's normal, but that's the way mine seems to be working

 

Sadly that is normal. It seems to be the PCM programming that doesn't give real time information. But when I get time, I'm going to ask someone on the Torque Forum. If you have an Active Regen and completes and you drive 10 miles and stop the engine, the DIA will show 10 miles.

Thanks again for the data. It helps with other PIDs I'm working on.

 

Well, we made it without incident to our destination in TN...The truck did great! Pulled the grades in the foothills of the Smokies 5th or 6th gear, no problem. MPD56, When we started this morning DIA read 428.6, around 80 mi into our journey it did an "active regen". So I think you were correct in predicting the 500mi interval for the "active regen". When it started regen my soot% was at appx 65%. The "regen" only lasted 5 mi. Soot% went from 65% up to 70% then as temps rose to 1100-1250 deg range the soot% dropped to 22.5%, regen ended after 5 miles, but soot% continued to drop for another 4-5 miles, down to 9%. Soot Mass went from around 1.6 to 0.2 in that same time period. I averaged 10.3 mpg on this trip. Thats pulling our 5ver at 60-70 mph and includes about 45 minutes total idle time. My truck just turned over 1200 miles, and I can't say enough about it, I haven't been this excited about a vehicle in 20-30 years. It feels good, Ford has built the best Truck out there IMHO....It runs like a hot rod and pulls like a tractor! LOL

 

Thanks for the data, it helps. I don't get to 500 miles that often so I can’t put my finger on the 500 mile mark. From my old memory I believe that there is a Soot % limit that when you reach 500 miles the PCM will start an Active Regen. I thought it is was 80% but looking at your data and back at mine, it could be 65%?

Thinking out load, I haven’t proved it, but if you were below a certain Soot % and reached 500 miles, the PCM will decrease the DIA by 150 miles and I’m thinking that is why some owners by their odometer can travel longer between Regens.

Anyway enjoy your trip and new truck. Thanks again for being a Test Pilot and posting your data.

 

We put about 150-175 mi on our truck yesterday, empty. It did 3 active regens. 1st one was in town stop n go 45 mph speed limit. Only last a few minutes, soot 98% to 65% then went off. Later got on hwy 70mph, regen lasted 10 miles, soot 99% to 8.6%. Then more city driving, soot built back up pretty quick, on ride back home did another AR, but only last 5 miles, soot 85% to 24%. I'm amazed at how fast the soot builds up when I'm not towing. It only did 2 AR's in 700+ mile towing my 5ver. I guess my old 6.4 did it too, but I didn't monitor it like I am the new truck.

 

Great info. I don't notice any real improvement in towing mpgs vs my 6.4 either.

But a lot less active regens.

 

GW09F350: That’s great info. You’re adding new pieces to the Regen Puzzle. What was the DIA showing? My guess is that on one of the Regen’s it didn’t zero it out. You have to remember that the 6.4L didn’t have DEF. My theory is that when you are using DEF fluid, the exhaust can’t get hot enough for a Passive Regen so Soot builds up faster in the DPF. Also your truck is new, the PCM resets a baseline to account for ash residue (New trucks the math is a little different to you get miles on it), I believe that the 6.4L resets when you first turned the key on because it is using a DPF differential pressure sensor, the 6.7L doesn’t.

I’m trying to work on a PID that hopefully will tell me when I’m using DEF. I have a SCR document that Ford submitted to the EPA, I start to read it and I feel like banging my head against a tree instead.

Thanks again for the update. I’m going to be travelling with my trailer next week so hopefully I can do some testing instead of guessing.

 

DIA for 2nd regen (10 mi on hwy) was showing 401 I think. Now its @ 49. Have restarted several times today and DIA hasn't changed, so that must not be what updates the DIA reading as I thought earlier.

 

GW:

That is interesting, you could be right. The PCM and Torque Pro sends and receives data by priority. Although I assume that you haven’t changed the settings in the PID, I did while testing and the DIA didn’t change also (froze). There should be a blinking green light (dot) on the display that I believe will tell you that Torque is sending or receiving data for that PID. Also if you change display screens and back, if the display doesn’t refresh quickly (or slow to show a value), it could mean that it is getting data or might not like one of your settings. Example: my friend’s older phone won’t work with the Header set to auto and my phone will, his phone won’t work right with the Bluetooth set to fast communication?

As you know, I’m new to this and your data is helpful. Thanks again for the information.
