I answered these questions myself...and GDE isn't doing the tune anymore and on U.S. vehicles
What is "regen" and is the GDE tune thing still avaible?
I was looking at people at were talking and Green Diesel Engineering Grand Cherokee EcoDiesel (WK2) Hot Tune and it looks great, a few questions:
- people mentioned "Regen" especially when talking about some factory warrenty flash...what is that?
- Is that CDE tune thing still around or is it "illegal"...says it's sold out
- Seem like a no brainer, any reason NOT to do this on a out of warranty 2014?
Thanks!

A regen is short for regeneration. There is a big filter in the exhaust to collect particles of soot. This eventually gets filled up and if let fill too long would create a restriction--think of a clogged air filter, but on the exhaust side. Instead of changing the (very expensive) filter every few hundred miles, the truck self-cleans the filter by dumping unburnt diesel into the exhaust. This burns in the filter and gets hot enough to turn the trapped soot into ash which blows out with the exhaust. This all happens automatically and usually without the driver being aware.
The GDE tune was a very good one, but unfortunately isn't available at the moment in the states thanks to overreaching by the EPA. Lobby your representatives to pass the RPM Act of 2019.

This is a good answer about the "Exhaust Regeneration in Progress" notification. I NEVER had this until they did the "modification". I then got this alert about 4 times until "exhaust filter almost full"...then more "regen" alerts finally "Exhaust Filter full" alert. Dealer CHARGED ME $140 to "burn out the filter". All good for 3 months and started again. This time it is accompanied by "EGR slow to respond". More "Regen" alerts etc. EGR valve is "on order" (5 weeks now) and will be covered by warranty.
GDE has indicated they will have EPA compliant tunes possibly in June. The pandemic has slowed their progress down. They have been selling to Canada since september.
Interesting.....What might this tune do for us?
Supposed to be very similar to previous versions, just not touching the EGR function. I would suggest if you have FB account is to follow them on there.Interesting.....What might this tune do for us?
Here is link from ram1500diesel.com... GDE EPA compliant tunes coming soon
Thank you......PLEASE tell me that this will be available for the Jeep Grand Cherokee Eco-Diesel....(same engine)
It's my understanding that the JGC will be included in the new tunes. They are shifting from sending ECM to them to a handheld device that will download the tunes.
By the way I did get a hand held off road tuner from sofakingtuned. Works well and you do it from your device. I had the GDE but the dealer accidentally flashed it.
my SKT is scheduled to be delivered today. I'll do a write up once installed & get some miles on it.
I have GDE in my Ram. It's nice, but nothing spectacular as far as performance.

Its not a super aggressive tune, but its verrry smooth.
