Now that my 2015 is about to be out of warranty, lets really start compiling info on deleting, or at least deactivating the troublesome EGR, DPF and DEF systems from our diesels. Some forum members have claimed successful deletes, but never actually follow up with more info. Self preservation? Perhaps. But maybe just internet falsity. I invite those that have successfully deleted the hardware chime in. The goal here is to determine what is the least intrusive way to effectively disable the EGR, and DEF systems, while modifying as little hardware on the van as possible.
I optioned my van with the "active regeneration inhibitor". I can actually shut down the auto regen when i know i'm not doing a long enough trip to fully clean the filter. I rarely use it, but it has come in handy when i notice i'm stuck in a driving cycle that results in the DPF cycling from 80-100%. I turn off the auto feature, until I'm ready to drive all the way home, allowing the regen to complete.
I'm wondering if turning off the regen also disables the DEF system temporarily, or is DEF constantly being injected into the exhaust, independent of the regen cycles? This knowledge would be key in determining if, once the DPF itself is physically removed, or gutted and fitted with a straight through pipe, it would be as simple as inhibiting the active regen via the settings the screen.
Then next question mark is the EGR and EGR cooler assembly. Unlike the larger diesels, there is no aftermarket delete kit, or upgraded replacement available at this time. There are several discussions around the internet regarding weather or not electronically commanding the EGR valve to stay shut (EGR off) will actually increase the life of the cooler. My opinion is "kinda, maybe". However, the EGR cooler itself is covered under a Ford extended warranty. My van is at the dealer getting it replaced for the second time right now, with a mere 114k kms on it. First replacement happened at 60K kms.
Finally, the electronics, or tune. xphobe has really done us a great service by pursuing this matter. Read up on his adventures in tuning here: FINALLY...flash tuner for 3.2L powerstroke
