I wish Ford would allow the driver to active the regen process manually.

 

I have found that downshifting for me makes no difference. Others may tell you it does.

 

I've found that right around 2000 rpm is the sweet spot for a regen. Anything less and the turbo adds boost to compensate in order to keep the EGT's high enough. EGT's not staying hot enough or fluctuating a lot causes longer than normal regens.

 

Yeah, I found it has to be at 2000 RPM or more to make a difference. Once you get the notice, just take it for a 25 mile drive. BTW, I had one regen last 38 miles with all others lasting 15-30 miles.

 

I usually fire up Forscan on my phone and take a cruise until I see the Regen stop. Never really looked at how many miles, I will next time. I do watch the RPMs and interestingly the last Regen I was on mostly back roads around 1500 RPMs. It did finish and the soot level was under 10% when it was done.

 

Regen behavior is one of the mysteries of the universe that requires Steven Hawking's attention .... but he is gone. We are doomed.

 

A 5 mile drive is hard on a diesel. it doesn't have time to come up to operating temperature and the transmission is just to cold. If you dont drive this truck that much you will regen more often than most.

 

You need to get out of the city and get on a highway or freeway to drive faster to get those EGTs up to burn off the soot. My last regen was 498 miles since last one and lasted 18 miles. I was on an expressway I take home and drove by my exit because I knew I was close. I keep on driving until it shut off. The EGTs got up to almost 1000 degrees. I obviously was in 6th gear as the speed was 65mph. I've seen them higher before during a regen. The last two regens before this one were 18 miles also. The third last one was 20 miles. You get the idea. I always get on a expressway or highway. Not always possible though but most of my regens were completed. Remember to put your truck in park and wait a little bit to shut off the regen if you get to your destination. If you don't have a digital monitor, you can't see it. Lots of guys here monitor their PIDs to see what's going on with EGTs and Regens. Just do a search on here to see what different things guys use. I use a Banks Power iDash.

 

 

The Keys... Nice. I was in Key West in 2006 as a single man during Fantasy Fest. WHOA... What a great time but I digress.

These trucks are much happier when you are able to drive them on a highway at highway speeds to burn off the soot when the DPF loses flow when it loads up w soot. If not, you will get the "Drive to Clean" message because the filter is plugged up. You can also do a manual regen if you buy an Edge Insight CTS2 monitor I believe. They can also do manual regens at the dealer. Your truck has to regen on a regular basis or the filter will plug. Delete is your next option. Good luck.

 

You can lock out 5th and 6th gears during a regen. A manual regen runs the engine at 2000 RPM so you need to get them up there to help. Both 5-Star and DP-Tuner tow tunes extended my regen interval some because they don't shift to 6th until 45 mph vs about 38 mph stock. You could just use Tow/Haul to keep RPMs up a little since your speeds are so low.

 

I really don't think driving in lower gears helps. The Increase in RPMS of running in lower gear at a higher RPM just pushes more air thru the engine and the EGTs drop.
Unless you are working the engine, ( Turbo Boost) that will increase the EGT's and help increase the heat in the DPF then the higher RPMs pushing more air thru will speed up the process.

The Regen process depends on heat to clean the DPF, You can watch your EGTs ( on 3rd party monitors) and see what kind of engine load produces the most heat and hence the shortest regen cycle

 

I would turn on the ability to do a manual regen. This way the thing can sit in your driveway and regen.

 

Great tip Chuck. Then whenever he knows truck has to REGEN, do a manual one in the driveway. Then you know it's clean. The Edge monitor has the ability to manually regen I believe.
