OBDTUNE.COM - Delete - 2017 3.0 Sprinter

[vteccred]

I believe I gather enough info from fellow members to make this happen. Since the ECU has been bench tuned, I spoke with the tuner, and they agreed to delete the "software" side and I'll be doing the "hardware" side on the driveway.
My plan is to remove ALL the components related to the delete. Replace the DPF/CAT with straight piping (hopefully it won't resonate terribly) Unless a member recommends a straight pipe with resonator is the best option from previous experiences. Remove the EGR and cooler completely is also the plan. Fabricate end caps on the downpipe, and intake.
But here is the dilemma, a pressure sensor and oxy sensor will NEED to be placed back for proper operation. Of course the new downpipe will have the bung for the oxy sensor.. What about the pressure sensor that is on the cooler. Should this sensor be placed in its original location , somehow. Or can it be threaded on the fabricated end plate on the downpipe. I read a commment from IVAN that close to the turbo, the heat exposure eventually will damage the sensor.

please let me know of any work-arounds, suggestions..

Can't you just chisel the honeycombs in DPF to make empty housing?

I highly recommend the resonator option. It will
Drone miserably over 55 mph (88 km/h) unless it is in place. The Diesel Doc kit for the V6 diesel is built like a brick outhouse. All stainless materials. The resonator is not a muffler and it adds no restrictions. It absorbs some of the less desirable frequencies via a perforated tube with stainless steel wool packing material wrapped around it. The exhaust passes
straight through, no baffling for the Diesel
Doc kit.

Regarding the pressure sensor--have a look at this video, it will help.

I certainly can.
I would think replacing it would save time and make the process easier. Planning on removing egr cooler, def tank, sensors.

Sprinters do have DPF with some piping attached, when my Bluetec sedan had DPF with short nipple before the flange.
Took me less than 1 hr to chisel all the honeycombs, when I was doing it with 2 screwdrivers, on the edge of garbage can, since I don't have workbench and was taking photos during the progress.

No black smoke and the soot goes through the CAT without blocking it. The only thing you will see is a bit soot on you back doors with time... You simply wash the van.

As far as egr, the egr valve on OM642 engines is located after the egr cooler and when it is discounted/closed for a long period of time it can plugged the egr cooler. I have seen this happen.

What I do in some of these cases is, I remove the egr cooler along with the egr itself and use 2 block off plates, and I reroute the coolant line.

What happens weeks or months down the road? Does the EGR cooler plug up over time with the EGR disconnected permanently? I’m looking to do a partial delete with DPF active and leaving the cooler installed. I keep getting information that there will be no exhaust flow with the EGR closed and disconnected. I’m not sure I believe that. All that soot will plug the cooler and then, what? More Exhaust Back Pressure? The cooler gets too hot?

Great question, and I am watching this myself. If it clogs, I don't think it will be an issue since the goal of the delete is to stop the flow altogether. I was concerned there could be some gas escaping into the intake, so I backed-up the delete tune with a thin steel blockoff plate that also functions as the gasket. If the cooler cracks or otherwise leaks coolant, then I will remove it completely. Who fabricated that really nice block-off plate in your first picture? That's a really good looking delete!

What I have wrote above only applies to the situation when the ECU is reverted back to original settings/EGR functioning. If you don't plan to revert back to original settings, you have nothing to worry about... It wouldn't apply to your situation even with the DPF still functioning.
