Re: green diesel engineering tune

I think I've asked most of these questions already so hopefully i can help without botching anything.

A good example is the recent shifter recall. If they plug into your car and you don't have the updated software, they will want to upgrade immediately since this is a safety related issue, not a regular TSB.

I bought my tune AFTER I'd had the shifter flash done just so I'd be on the books as having had it done. Everything will look normal the next time they plug in since that update has already been included in the tune.

If I buy another ecm to insert when I go to the dealer to save my GDE tune won't I miss out on some updates that I want/need?
Yes, but a better option would be to just do the advance ship/swap option so you're never without a working vehicle and you're not out another 650$. You can keep an eye on this site to see if your vehicle even has any TSBs out for it, or if a specific issue you've been having has been noted.

I don't believe they will go flashing your ecu willy-nilly unless a) its a safety related TSB or b)you are having an issue that corresponds to an existing TSB.

Quote:
How often or how many times a year should you get it updated from GDE?
I know they periodically update with new features, although honestly there are several different standing threads in diffrent forums (ram forums, jeepgarage, etc etc) in addition to the GDE forums so I'm not sure where the best place to get current info is.

Re: green diesel engineering tune

Thanks guys for the responses. Just a couple things to confirm my understanding.

So, we can be fairly certain that we won't lose our warranty due to the tune?

On a new vehicle I can be reasonably certain I won't be missing out on any needed updates unless there is maybe a safety issue or new feature I want that would be resolved by sending my ECM back to GDE to be updated after the dealer flashes it. And GDE will have the newest updates.

And the ship / swap option will cost I think about a hundred bucks.

I think the performance of the stock CRD would be fine for me but I am more concerned about the best health and longevity for my engine.

Your assessment is correct, though it should be clarified regarding terminology. A recall is a recall... meaning there is a campaign, the government is typically involved, mailings go out, etc. A TSB is a technical service bulletin. These get patched/fixed only if an owner complains about the issue the TSB describes. We're on the same page so far.

There's one more wrinkle: the RRT. Certain TSBs are promoted to RRT status. You can think of RRTs as "unofficial, not safety-related, recalls". You can see if your TSB is an RRT if there is an entry in the RRT field next to it on the WK2jeeps page. One example of an RRT was when they changed the oil spec for the 2016's and dumped/replaced the oil in all the unsold Jeeps.

RRTs are still TSBs... they're just special. They have both a TSB number and an RRT number.

They will automatically flash any recalls *as well as* any RRTs. "So what?" one might say. Well, it becomes salient if, for example, once upon a time there was a critical bug in the PCM firmware for your model year. That implied the next PCM firmware release that fixed this critical bug would be an RRT instead of a plain old TSB. Seems reasonable, right?

Okay, but now remember that these firmware releases are *not* modular. Therefore, if *any* firmware release was an RRT then *all subsequent* firmware releases for that module will inherit RRT status, even if all the subsequent releases do is something trivial and would otherwise be one of those optional TSBs.

This is exactly what happened with the 2014's and 2015's. For the 2014's, about 10 months after they were released a PCM RRT came out. Every PCM update after that (even the trivial ones) was therefore an RRT. I think the average has been ~2 PCM firmware updates per year for the 2014's (most recent one for the 2014's was released in Feb 2016)... all have been RRTs, after that first critical one.

You will need to be careful if you don't want your firmware overwritten. Either check to see if there are any RRTs or recalls for your PCM before you go into the dealer, and/or be very explicit with them regarding what you want updated or not (and then hope they comply).

Re: green diesel engineering tune

Correct me if I'm wrong but isn't the shifter recall an update to the TCM? Or BCM? I imagine you could get it done while telling them to not update the ECM (and overwriting a tune).

One of the main reasons I run the GDE tune is the cleaner running engine. Crazy how clean the oil and intake stay once tuned.

Unfortunately, you are wrong. The shifter of doom recall involves flashes to multiple systems' firmware, and it will overwrite the GDE tune on your PCM as well as reflashing the TCM, etc.

Re: green diesel engineering tune

So what does RRT stand for? and TCM and BCM?

Re: green diesel engineering tune

And it took a reflash of the software for a new oil?

RRT = Rapid Response Transmittal
TCM = transmission control module
BCM = body control module
PCM = what FCA calls the ECM (haha)

good info. I was thinking about stuff like the multiple TSBs for things like shift enhancements. I don't think those get done automatically, I had to go in and specifically tell them I had the 2-1 downshift bump described in 18-xxx-whatever to get that flash done.

Yep, that's how regular (non-RRT) TSBs work.

Protip: if you want a particular TSB applied, print out the PDF and bring it with you to show to the service writer. When they're done with your vehicle, confirm it was applied by looking at the invoice. I've had service people tell me there was nothing to apply/fix when I described the exact problem in the TSB. Then I handed them the TSB printout that clearly referenced my vehicle, and it got handled.

It's a fine line to not be "that guy" who walks up and dumps a sheaf of papers on the service person and says "I want all these", but I've also had to leave without the latest firmware simply because I didn't have the TSB printout with me. Lesson learned.

Isn't this going to overwrite your tune? I guess I'm wondering with a new model year if I want to bring this tuned ecm with me to pickup the Jeep from the start or maybe drive it awhile in case they have a lot of initial updates I may want.

As far as shift enhancements, are those determined by TSB's or by the GDE tune?
