Update on my 2015

Egt's are a big issue. Need it to run hotter at cruising state. Maybe retard timing to increase egt with a later combustion event?

I think that's pretty much what I had said previously, so I'm not sure if we are agreeing or disagreeing lol. Either way, I've spent a lot of time working with Eric on tuning, and numerous hours on the phone with Morgan in conversation about this particular "problem" i guess you could call it. Between the three of us I think we've come to agree that it's related to passive regen, tip-in lag allowing fuel(soot particles) into the exhaust stream at a higher rate than experienced in a stock turbo form, and a increase in exhaust pressure against the dpf load. My truck with a clean DPF drives completely different than it does when particle matter starts to build up, which isn't really a shocker I'm sure lol. Backpressure is live in the downpipe toward the higher end of the load spectrum though, enough to crack a 68lb gate reference and bark the charger on shifts, low RPM driving, or under the charger on any type of incline grade in 5th or 6th. Usually at that point, the truck limps and i've gotta force a regen to get back to square 1. Of course that happened about every 100 miles on the aggressive tuning, and less with others. Eric does a great job of tweaking files so I can keep trying though. He's gotten much closer recently. The newest tune in my truck hasn't limped in two tanks of fuel, but regen cycles are still continuous, which like stated is more or less related to the efficiency of the 64

I talked with Morgan again this evening and I told him this as well, I'm gonna try my 4" downpipe and see if the added volume will be enough to help any of the issues the truck is facing. After that, I'll be adding a 60mm gate to the downpipe with boost reference and moving forward. Ultimately, thats not what I'm wanting to have to do(as far as the atmo dump gate is concerned) but if it helps and tuning isn't able to correct what the setup faces, It is what it is.

What turbo tables are you using? I've tried several tunes with modified tables and some with stock, so far the modded tables i've used seem to be the best. The stock ECM tune file and the 64 experience the same issues as the aggressive tuning, it's just not as persistent.

Tadd and I had talked about the 60mm gate to bypass the dpf about a year ago with the non vgt single kits.

Modded 15 turbo tables. For you using a 15 to begin with you have a good start. I had a ton of work in making that right with the help from mike Haller. I have retuned my truck in over a month. I'm pretty happy with how it runs a drives. I can't make it smoke for the most part.

I've never had any symptom of the dpf plugging like that. It's always driven the same no matter what even dpf off I noticed very little gain in spool up or overall hp.

Maybe his low boost fueling is more agressive. I know the tunes I originally started with were a little smokey on bottom I have the lambda tables all set above 1.2 which makes the response less but you almost can't make it smoke untill it starts to make good boost.

This is all on stock intake

Powerstroked162 · Jan 1, 2015

Right on. I didn't think i'd be setting the world of innovation on fire by deciding to use a gate in the downpipe as a cut out versus an electrical cut out lol. Got the idea from a guy who builds Evo's and other imports over here in Tacoma actually

Dunno. I've only worked with 15's DPF-on, so I don't honestly know what a older truck does with one. Most in the 11-12 and even some 13's now seem to be deleted or stock and interested in keeping it stock lol.

The dyno is gonna tell the tale for sure. Most of what is aggressive is noticeably stronger on the street over some of the base tuning I started with. Wanna know what still surprises the heck out of me? lol The canned Superchip tune, and the stock 15 OEM tune with this 64. You'd almost have to drive it to believe it

Dzchey21 · Jan 1, 2015

Who is tuning for superchip? I have heard that is the tune to beat on a 15 so far, least amount of smoke ect.

Have you tried to go back to the Superchip tune with the 64? Or even stock tuning with the 64 for regen cycles?

I couldn't run a stock tune because of low boost codes, and it flat out did not drive well

Truck turned out perfect man. Can't wait to see it a little lower!

Edge is, or the umbrella corp Powertech or tek. However it's spelled. I've used the canned tuning from them and not a single complaint with drivability. regen cycles never altered or changed with their 100hp tune(80whp on the dyno).

I've ran it, i've ran all of it honestly lol exhausting to think about. Regen cycles from the superchip tuning are still consistent with innovative tuning, while running the 64. It's just not aggressive enough tuning to cause the issues something with more fuel does. The stock tune never stayed in the truck for longer than 50 miles or so. Ultimately, the information i would have obtained from that as far as regen cycles, load etc., wouldn't have applied to anything with added fueling so I never worried about it. It did drive surprisingly well, i believe Morgan ran the stock tune for awhile with the 64 as well.

You've given me a little more to think about though on the tuning and DPF. Appreciate the help

O RLY?! I believe the last comment about lowering that you made was "GAF" lol

Let me know what you come up with on it if you have a solution that is not adding the wastegate. I am more than willing to try it out. I know originally i had said i was going to keep the dpf on mine but i think its going to stay just how it is for now. I put a muffler on it last week, now it is stockish quiet drives like a boss and no smoke so i am plenty happy.

I have another project im starting in two weeks that is going to consume a fair amount of time following that may lead me into the camping season. And then i wont be touching this truck except to lower the gooseneck on the truck LOL. So if you find something in the tuning let me know.

Powerstroked162 · Jan 1, 2015

Deal. Thank you again. Good to have some help lol

Might try less duty cycle on the VGT and/or lower desired EBP... in turn, bring the boost down and get the EGT up

retarding timing would hurt cruising fuel mileage

heck, less EBP might help fuel mileage at light load/cruise in and of itself

Jeff@Spartan · Jan 2, 2015

Glad to be apart of it brother! It's a beautiful truck and can't wait to see where you take it from here.

UpstateDieselGuy · Jan 2, 2015

Just a thought/question, along with the thought about needing a bigger down pipe, is it possible that volume/flow capacity of the entire exhaust has been exceded? The choking may not be remedied until the exhaust is made larger to match the higher flow/pressure/volume.

Great work!

Chris

Dzchey21 · Jan 2, 2015

Probably make it drive like crap lowering it too far because with Heat you will most likely get smoke.

There is a possibility that the dpf is maxed out but with a factory tune and a 64 you shouldn't be much over stock hp. That's why I asked that. When I ran mine I ran it on the lowest hp setting and it didn't change anything.
