I agree Tom. My use when not towing is very short runs all the time rarely getting up to temp enough to regen. Bringing my daughter to school. Out to dinner near by. Etc. Never once did I have trouble with my 2012. I'm assuming it will be the same with my 17.

 

I think what the OP is suggesting is something in between auto regen and OCR. Perhaps "Operator Influenced Regen" or OIR that would allow the driver to optimize the automatic regen to match drive cycles, get a more complete regen, reduce back pressure and thus increase overall fuel economy.

Here's an idea to improve upon that concept further. Apply some of the drive cycle learning technology (like what's used on the Chevy Volt) so the vehicle learns the drive patterns (based on GPS coordinates) to optimize the the regen cycle.

I believe the Volt uses it to optimize the use of the generator (engine). If it sees you're on your daily commute, following your normal route and you have enough battery capacity to reach your home, it won't run the engine. Deviate from your normal route, and it may decide to run the engine to charge the battery. There are probably other variables in the algorithm but I remember reading about it when the Volt first came out.

 

I'm not suggesting that it's a problem for the truck. I'm suggesting it CAN be a problem for my fuel mileage.

I wonder how long you have to be in park? Mine was at 95% when I started it earlier and it never asked my if I wanted a manual regen.

 

From what was discovered in the 6.7 section, those who enabled the DPF screen got the option to do an OCR if you were above 85% but only on 2011 and 2012's. Something changed and the 13-16 trucks didn't have the option. I'm not sure if the guys working on it with Forscan ever figured it out for the 13-16's as I haven't been following their thread of late. What year was/is yours? Was it up to temp? (This doesn't apply to 2017's...)

 

Mine is a 2017 with ocr.

 

Not up to temp?

 

Yeah it was cold

 

Just to jump in on this. I fit into the short trip mixed in with a long haul here and there and have some observations on regens. The truck has 2500 miles since Oct. and has been doing a regen at 375 mile intervals. I have not noticed any change in mileage during the regens and am currently getting 16 to 20 mpg without any towing but I have been hauling water. I have been monitoring PIDs with forscan lite on my phone. If the truck continues as it has been operating, there will be no good reason to watch it that closely. As some have said here....just drive it and it will take care of itself.

 

Tom, This would be my first diesel that actually regens. Ford engineers have written about a potential problem with regen in the owners manual. If you don't have the manual regen and your driving habits don't allow the truck to automatically regen, your truck will actually go into limp mode. In other words if you can't take your truck for a longer drive above 30 mph and you didn't order manual regen, your scewed. It is in the owners manual and I suggest everyone read this section. I ordered the manual regen without even knowing what it really did but probably because I figured the more control I have over any system the better. This thread got me interested on how the manual regen works so I pulled out the manual. I am SO GLAD I ordered it but I agree with the original post and I wish they took the manual regen even further to were you could activate it at any percent you wanted if you knew you were in optimum driving conditions for it. It only makes sense.
Let's say I was going on a two week elk hunt were I live and I know that I would never be driving over 10 mph due to the conditions of the back roads. I'm reaching my forest service turn off and my filter is at 95%. If I didn't have manual regen then I would have to pass my turnoff and drive up the highway for another 30 to 45 minutes just so I could get the filter clean for my two week excursion on the back roads.
Can you now understand why folks want manual regen.

 

I get the short trips but again, unless you ever see the warning screen (I saw it on a 2015 6.7) "Your Exhaust Filter is Full....Drive to Clean" ...The system and your driving are working together fine.

Regarding limp mode...this applies to running out of DEF and full exhaust filter. I have ran out of DEF and as expected, did NOT go into limp mode as I had not added any more fuel. Unless that has changed, you can drink all the DEF and drive uninhibited until you add another drop of Fuel. At this point the warnings on your screen will pretty obnoxious and you would have ignored a lot of warnings.

Same does for having a full exhaust filter. No limp mode until you ignore it for a said period of time. And that is if you ever get to that point.

Having had 5 years to tweak the 6.7 and DEF, I have no worries. The 11-16 were very trouble free and I woudl think this new truck is even smarter and more accommodating.

You own an amazing truck....just enjoy it.

Since you are new to this and haven't owned one, you probably don't know that is a VERY rare situation. Stop in the 6.7 forums once in a while. It's a complete non issue.

 

Exactly right!

 

Thanks for posting your insight. Not having a SD and not being familiar with Regen, this sounds like a huge problem.

I am, truthfuly, relieved to hear it's not the issue it SOUNDS like.
