DPF Questions

RyanD · Sep 13, 2014

Guys,

I've searched and searched, but couldn't seem to find a definitive answer.

A local guy I bought an intake from (appears to run a shop from his house) got me a little spooked about plugging the DPF given my driving habits (mostly short commutes, stop/start, etc). I know he was trying to sell me a tuner and delete kit, but I did some research that still left some concern. I set my Torque app up with all the DPF PIDs I could find (DPF Soot%, Distance since last Regen, Regen Active Yes/No, and Soot amount in grams per Liter).

Last night as I was pulling into my neighborhood it hit 100% and began a regen, so I kept driving until the Regen was complete. I expected the % to drop to zero, but the regen stopped at 12% full.

So, is it an accurate correlation to assume my DPF is ~12% plugged?

Consequently, I picked up a mini maxx last week (found a guy who wanted my AR setup, so score!). I wouldn't be so uptight about this thing if I didn't have a warranty and knew of a shop that would look the other way with a deleted pipe.

I use the same thing on my 2013. Soot shows 16-18% after a regen.

That's normal. To keep everything in the system alive, regen doesn't go until the DPF is at 0% soot mass.

Awesome, thanks for the info.

So, I'm guessing there really isn't a way (possibly that we know of) to determine how "plugged" the dpf is?

With such short commutes and very 'Camry-like' use of my truck, I may just delete to eliminate the worry.

I hooked the mini maxx up and ran it with the gauges only...all temps and numbers seemed good. I want to keep this truck a long time, so I'm a little OCD about its health.

Luke@MillerPerformance · Sep 13, 2014

The new trucks are much better on the dpf and dealing with short trips. That being said, deletes don't hurt

Nut up and delete it Ryan!

Good to know.

So, I've been looking, and I'm not seeing a lot of delete pipes that are stock sized. In the event I do delete, I'd like to keep the factory dpf-back. Does such a beast exist or am I crazy for asking? If I'm crazy, is there a turbo-back kit that doesn't draw the attention of everyone for 5 square miles?

Thanks again for the information, the forum has been awesome for helping alleviate worries.

I KNOW I KNOW. I am only married to a humble attorney, I don't have that doctor money to laugh in the face of a warranty with!!

I believe Elite has one

I also thought SPE sold one as does Flo-Pro

Sweet, my internet skills are lacking. Hope you're enjoying Alaska

Wouldn't it be nice to pull into your neighborhood and just go HOME. Instead of having to drive it off, because the trucks diaper is dirty??? Lol

I just wish we had a button for regens like the big trucks.

I doubt it will ever be 100% clean after it leaves the factory. how well does the torgue app work for the 6.7s. been thinking of getting it if I new how well it would work.. what all is needed for it?

Using VCDS, I can do a force regen on my brother 2010 TDI. I don't see how the aftermarket can't tap into the pcm to do a force regen for the powerstrokes?

It actually works quite well. All that's needed is the app on your phone, the Bluetooth adapter, and then download a custom PID pack. There are a couple guys that are working on getting as many PIDs as possible. Right now, you can monitor all 4 EGT sensors, trans temp, oil temp, regen status (on/off), distance since last then, soot%, boost, and a couple more. They're working on exhaust back pressure, fuel rail pressure and EGR. Basically, anything that can be monitored by a MiniMax can be monitored, if you can figure out the correct equations.

I believe the new edge offering allows control over regens. I thought I saw that somewhere in my reading.

An edge insight allows you to force regeneration

Works great if you have the PIDS. Pick up a cheap Bluetooth obd2 adapter from amazon (I paid $9 shipped for mine)... App is $5 on the google play store. It comes with an f250 profile, but some of the PIDS you have to load manually. I got most of them from a thread on another forum, but if y'all are interested, I'd be happy to post them all here.

Very cool. I think you should actually start a new thread regarding this topic. I'm interested in seeing your work/findings...
