Re: green diesel engineering tune

Man I was blissfully unaware this recall would be a problem for me, as I was thinking the PCM was not the same as the ECM. I really hope the the GDE guys can provide some clarity soon on how/when to handle this.

I guess the most likely scenario is it can and will be overridden w/ the updated stock FW at my next service, that by then GDE will have 'patched' the new version, and I can mail mine back in for their latest update.

If I recall the re-flash charge is $50 (plus shipping)? A necessary evil I guess, but to regain previously purchased functionality that feels a hair on the steep side.

Anyway, anxiously awaiting more info...

Re: green diesel engineering tune

We already have our tunes ported over to the shifter recall software. As soon as the dealer does the recall we can get the tune reinstalled.

It's best to let the dealer do their thing so that your VIN is off the list. If you find that the new logic intrudes upon your driving style, we can address its "shortcomings."

Regards
GDE

Would love to know more about this. Do you have something ginned up already or would this be a potential future option / feature, similar to the engine braking option?

Re: green diesel engineering tune

We knew these kind of issues would come up down the road when we bought the tune. Thanks GDE for getting the updates worked into the tune so quickly. I'll be holding out for as long as I can to take mine to the dealer.

Just as an FYI to everyone, this is an optional recall. You can decline it. I hope I can just sign something saying I assume the liability for it and make go away lol

Re: green diesel engineering tune

Just got back with a talk with my master tech at the dealership. He says that you do not have to have it done, but, if they have to hook up to the vehicle, it is a Federal requirement on the dealership, that is is installed. He told me just to install the original, I bought an extra with the tune, have the update completed and then send the green engineering back and have it updated. He didn't know what would happen if you installed the original Green Engineering tune back into the vehicle after the updates were installed.

I'd really like to see that regulation. My sense would be to chalk this up as lies service department personnel tell in order to make dealing with difficult customers easier.

The larger issue is that if you refuse this recall then your Jeep firmware for those four modules is frozen in time, from a dealership perspective. These software updates are not modular, so you either get the latest version or nothing. That is to say, they can't simply "not install" a single feature--it's all or nothing. So, let's say later on a TCM update comes out that fixes some sort of shifting issue... if you want that, then you'll have to also get the previously-released recall version auto-park functionality because that code will be included in all subsequent releases. BTW, that means that this recall includes all previously-released TCM/PCM/etc updates, if anyone was trying to avoid those.

Naturally, the GDE modifications to the PCM firmware changes the discussion, insofar as that module goes.

Re: green diesel engineering tune

As someone who has never tuned a vehicle, I'm having a hard time understanding how a simple software flash can improve our truck's performance and economy. If the truck is so easily tuneable to these standards, why would the factory not deliver it in this form? What is being given up? Is it emissions related, as in we will be polluting more?
I am genuinely interested in getting this tune, if only to see an improvement in off-the-line acceleration while turning left into traffic, but I am curious how a small outfit like GDE can do better than the tens of millions in R&D invested by the engineering teams from FCA / VM / ZF. This is a question in earnest and I'm not just trolling.

Thanks,
Tim

Re: green diesel engineering tune

No manufacturer tunes to optimal. They have to tune for a broad range of users not enthusiasts. That makes their tune conservative so that known reliability is preserved.
Also as is usually the case successive models get performance improvements although from 2014 to current no engine performance improvements have occurred. Most likely because FCA knowing this is an Italian engine sees no need to do it unless it is done in Italy where this engine is widely used.
Dodge Ram and JGC hardly fall into the mold of performance models. I do plan a tune once my service plan ends 120 k miles/ 8 years.

I'm not positive on this, but my understanding is in general aftermarket tunes tend to get at least some of their performance boost from turning off EGR, which yes will increase pollutant output. Basically what VW was caught doing. If I recall I remember reading they also boost the line pressure or something like that to the turbo, so that it spools up faster. Which you could take to mean over very long periods of time would put wear on the turbo faster. But I'm sure that FCA has built such a level of safety into settings like that that you could make some tweaks that are still safe and get better performance, just a little "less safe" with respect to life of the parts... Again, these are just my mildly informed hunches. I'm sure others that are better experts on the matter can clarify.

EDIT: Forgot to point out, I highly recommend the tune. It makes the GC perform how it should perform. Also, I've had a tune on my V8 Dodge Charger for 100k miles and had no issues so far, for what it's worth...
