My CTS also revs to 2k rpm and engages the fan clutch 100% during the length of the parked regen. I've noticed that when you do a parked regen with a snapon OBDII tool the fan clutch sometimes doesn't engage.


Not really sure why you didn't just let it regen during the tow trip, not going to hurt anything unless you just wanted to play with it, but thank you for your insight for the rest of the readers.

 

I plan to test my DP-Tuner Heavy Tow tune with the same trip that I tested the Light Tow tune with and didn't want a regen interfering. Ordinarily, I would just let the regen complete with the next drive. Last time, I headed out with the Light Tow and returned with the Heavy Tow and am doing the reverse this trip.

 

Gotcha, and makes sense now that I've followed up on your post in my DP Tuner thread.

Let's see the numberssss..........


I'd always play it safe with the 35 horse over 50 when doing that 10k trailer even though it isnt an extreme amount of weight, I know advanced timing under a full load over time doesn't play real nice.

But then again, Jody tunes fairly conservatively.

Aw hell its a damn crapshoot.

 

i didn't know there was a way to see what % your DPF was at on these trucks…where do you go to see that?

 

You can have it added to your gauges (top menu selection on the dash) by your dealer or do it yourself with FORScan. Many dealers don't know the process but it is to turn on Forced Regeneration in the settings.

This is how to get to the %DPF screen for "Exhaust filter".

(1) IDS "talking" with truck via VCM

(2) Toolbox selected to get to the Module Programming

(3) Programmable Parameters for our trucks

(4) Select Personality Parameter to program

(5) Change "Forced Regeneration Request" to Enabled.

(6) Programming complete and VCM can be disconnected from truck

Ghost Screen now appears

 

With FORScan go to:

-"IPC as-built"
-scroll to 720-01-01
- there are three boxes, the first one don't modify
- second box insert "9" in the first of the four places to turn on DPF % (put a "1" to remove the DFP %)
- in the third box put a capital "E" in the first place to set "Force Regen" to "off"
..........................................."F" to set to "Force Regen" "on" but "Compass" will turn "off"
..........................................."6" to turn off "Force Regen" but "Compass" on
.......................................or "7" to turn "on" both at the same time

-save and exit
-cycle key

Done

 

I just installed a used (30k miles) DPF on my 2012 truck. The diesel specialist was kind enough to do a flash upgrade to my computer, and it added the manual def option. As this was a used DPF (got it for 400 bucks, plus 200 to install minus 200 recycling.)I wanted to start with a clean filter. Started at 90%load, took about 15 minutes and used .6 gallons of gas. Love it. down to 0% on the meter and -12% load on my FORScan (iOS).
My DPF was cracked and not catching all the soot, so I decided to change it before it got worst and dropped a code.
Anyone know if it does any harm to do a Manual rather than wait to drive it? It's a daily driver, so not always able to finish a Regen on the road.

 

Manual regen is what the dealer does when you take it in for DPF issues so it doesn't hurt it. It is more cost effective to let it do it while driving as some of the driving heats the exhaust.
Did you mean .6 gal? That is the usual amount.

 

I can't find it on my dash screen. I must have Optional message center, because my steering wheel doesn't have a Info button. When I select Gauge Mode, the scroll to Information it doesn't show anything about the filter. Just My Drive.

 

You have to enable it with FORScan

 

I have a 2012. I never had the screen either. When the shop installed my used dpf a couple days ago, the tech was kind enough (No extra charge, and it wasn't a stealer) to install the latest module flash. It automatically activated the Operator commanded regen. I had to scroll right on the gauge menu, and it showed the dpf load. Once it reached 85%, it automatically gave me the option to manually clean it. Pretty cool, and a great option if you don't have a chance to drive to regen. I feel that .6 gallons is very reasonable.

I have the 3rd screen activated on my 14 and can see the filter % and watch it decrease as it is in regen. However, mine does it when it gets full.

Does anyone know why my 14 doesn't have a manual regen?

The only time the manual regen option will show up is after the load gets to over 85%. I didn't think mine had it either after they upgraded the module because it only showed the percentage. Once it hit 85%, it showed a "Press ok to clean" button. Also, you may have to have it in park and the emergency brake on.
