Regen Question
I just got a CTS 2 on my 450 so I can now tell exactly when it is or isn’t in regeneration. It turned on today with the filter at only 33%. Stayed on for 16 miles until it was down to 6%. I believe I read that it kicks on every 500 miles, regardless? Is that true, if so why?

My closed loop is usually around 30% or so when regen starts. (I'm assuming the ol and cl prefixes are open and closed loop.) The dash gauge is just the open loop soot % (rounded up to the nearest 5%) above 35%, and drops rapidly to 0 around an open loop reading of 20%. Regen stops around 30% and continues to drop to 0 if driving at highway speeds and 20 or so (dash reading 0) in slow stop and go traffic.

Not much. You might avoid driving through deep brush if you know a regen is imminent. It could be very useful if Ford would allow the owner to participate a bit. I'd love to tell the truck "I can see you need a regen soon. This is a great time, I'm going on a long drive." I seem to have bad luck relatively frequently and the truck won't regen on the long drive until the last two miles. In that case, as you imply, ignorance is probably better than being frustrated with Ford.

I plan to do the forscan one to turn the dash spot level gauge on, but the Cts2 gauge has it as well.
Im sure I’ll learn more as I go through more regens. Just a waste of fuel, wish there was a better way. Would love to delete, but can’t risk it with the warranty on such an expensive truck, especially since I have a 125k bumper to bumper warranty.

The thing I despise the most is EGR. It seems like a really bone-headed way to reduce NOx emissions. Just let these things operate at high efficiency (high temperature) and blast the NOx via increased DEF injection. If I've got to have the complexity of a DEF system, lets use it sufficiently to remove the EGR. The engine would be more fuel-efficient, less complex, and more reliable without all that EGR crap and I'd happily burn through more DEF to achieve these objectives. I expect you could even vastly-reduce the need for active DPF regenerations if you ran higher combustion temperatures (fewer particulates and more passive regen). That being said, I'm no expert... just pointing out that EGR seems like an incredibly stupid design that started as a way to achieve emissions targets at minimal expense. Since we're all running DEF now, it seems like we might as well go whole-hog and toss EGR.

The biggest thing for me is avoiding pulling steep climbs while in regen. You'll lose power, and generate a huge amount of heat. If you enable manual regen, you can avoid that. I'm in a flat area so I've left it to auto for now, but if I ever end up on the west coast again you can be sure I'm going to control when it happens.

The dealer can turn off the auto regen on the same screen that they use to put the DPF status on your dash.

I've run scan gauges for years, and on my current 2017, to monitor regeneration. I can't see an "on" switch for passive, by can see the sootload actively drop. Mine usually goes into active at 100% sootload, but will approach 104%.
This week, mine went into regen at 107%, and stayed there for about 5 minutes. Then, within 1 minute, dropped like a rock to 68% and down to 25% where it Immediately shut off. I continued driving and it dropped to 15% while still cooking. I've witnessed TONS of regens over the years, and I've never seen a regen complete in under 10 minutes. My 2017 always takes a good 30 minutes to run a complete regen from 100% sootload to 10-12% where it shuts off. This week, it was done in less than 10 minutes. The first 7 or so it never moved, as I assume it is heating up. We'll see next regen. The last three I've purposely run until it completed. All ran about 375 miles between regen cycles.
