Can anyone offer insight into this? I have the GDE tune and my truck ran two regens within 100 miles the other day. I'm in Iowa and it's been below 30 degrees for the week. If I don't get the truck up to operating temperature on every drive, will the colder temperatures cause a quick build-up of soot? I noticed this last year as well - prior to the GDE tune - and this eventually led to the failure of the EGR cooler. Maybe this was a fluke, but I just wanted to see if anyone else has experienced anything similar. Maybe I just need to make sure that I'm getting the truck up to operating temps on every trip.

I have definitely noticed that a cold engine reduces regen distance. The actual mechanics of why i am not so sure, but it probably has to do with a cold combustion chamber not fully burning all the fuel until it comes up to temp... this would create soot.

I will say though, if it regen'd twice in 100 miles thats odd. Did it finish the first regen? i have never seen less than 250 miles on a GDE tune.

Thanks for the reply. I thought it was awfully odd as well. I've driven a couple hundred miles since then and it hasn't regen'd again.

I may notice a slight decrease between regens, but not 100 miles...unless you left your truck running for a few hours.

Do you have the regen msg option? Did the first regen complete?
I do have the regen message and it did complete. That initial regen happened on Monday morning - I had a little extra time on my way to work - so I kept driving and let the regen complete. I made two short trips where I did not get the truck to operating temps on Monday evening/Tuesday afternoon, and on Tuesday night on a long trip, the truck started its second regen.

Odd for sure. I'd ask GDE on Monday. I've kept track of all my regens since new, and been GDE tuned since new. Shortest interval was 250mi but the previous regen stopped at 20% for an unknown reason.

Longest interval was in the 2500mi range due to passive regen while towing.

Do you have an Edge CTS (or similar) monitor in your truck? Would that be beneficial to have something like that?

It sounds as though for whatever reason the first Regen didn't fully complete. There is no way a GDE tuned truck could go from 8% soot to 80% in 100 or even 200 miles of driving. Yes the CTS or similar gauge shows soot percentage and you can monitor what's happening.

That’s what I thought, but it happened. I made sure to allow the first one to finish, but I’m wondering if it was just a fluke. Maybe an error with the screen, software, I don’t know. Is there a big enough difference in the Edge CTS1 and CTS2 to justify purchasing the 2?

I'm not sure if there are any differences in the CTS 1 vs 2 except the screen layout. Maybe someone else will know. I have the CTS 1 as 2 wasn't available when I bought it. Here's a picture of a CTS1. image.jpeg . You can choose quite a few gauges to have on screen. These are just the ones I had at the time.

Thanks for the info! Happy Thanksgiving!

Just some suggestions and comments. My stock ecodiesel will not start regen until 50 degrees Celsius or 122 Fahrenheit. At times I have short trips with mote frequent regen. Use the block heater in cool weather as it will reach operating temperature sooner. Use a timer with the block heater, if able, to avoid wasting electricity.
