GDE is back and making EPA compliant tune!

[biodiesel]

Any update on this?

No updates since I posted a week ago. Expect a fall release. We still don't know if it will be an ECM swap or flash tool.

As of right now, CARB will not accept GDE's testing results. So, the GDE tune is EPA compliant in all 49 states, but it will not be CARB compliant in California unless an agreement surfaces between CARB and GDE. Sad to say the least.

But not shocking in the least bit.

Can someone explain differences between PPEI, GDE, Banks tunes. I have been looking forward to GDE tune since before I had the Jeep (Sept 20). But I guess I don't understand the differences between the tunes, what their benefits are, how they are installed and how they affect warranty. My last diesel was a 12valve Cummins and I tuned it with a screwdriver.

With 37s, I NEED MORE POWER!! Pulling my 4k lb camper over MD/WV mountains is tough. Likely regearing to 4.30/4.56 but really want the best full mileage and power combo I can get, which is the whole reason we buy diesels to start with.

Thanks for any info.

I will give you the short answer. Banks is not a sophisticated tune with customization. PPEI and GDE are great tuners. The 2020+ EcoDiesel will be tuned either by ECM or a flashtool. Due to their background knowledge and skill sets, GDE is still considered the leaders in the tuning business when it comes to the EcoDiesel.

how they affect warranty.

I don't think any tune offered will stand behind their product if warranty is denied due to said tune. Most have an "offroad use only disclaimer" or some way to insulate them from damage claims. For example, you can read this.

So far, I don't know anyone who has been denied warranty with the GDE tune, mostly because it's not easily detectable. You can flash it back to stock for warranty purposes. Dealer has no clue that you have a tune.

Bank’s tune is not bad, but it’s solely a performance tune. They are pretty clear about that fact too. Cleaner burning, less soot, better gas etc. none of those are considered as it’s not the intent of their tune. They also have good protections in place to make sure the engine isn’t over pushed/work. The tune is set up to follow default safety parameters.

Let’s not forget too banks offer probably the most reputable of the companies you listed.

What about the Mr. Tuning tune? That company has been around for awhile with the Ram and Grand Cherokee Ecodiesel and has built a strong reputation. They also have a tune that can be flashed prior to a dealer drop off and theirs even shuts off the EGR which makes everything 10x better when it comes to engine longevity, mpg and performance.

GDE tunes for efficiency. He leaves all factory parameters in place.

Reputable? Knowledgeable diesel enthusiasts will not buy Banks. Banks really can't be compared to GDE. Banks tricks the computer to make more power whereas GDE reprograms the computer with a more efficient combustion and adjusts the EGR for efficiency. GDE tunes the engine and transmission for longevity.

Mr. Tuning isn't legal in the U.S.. If you want illegal tunes, then that's a separate thread for a separate topic.

So it's like I said. Banks is a performance tune. They are not concerned with the other stuff. You could have just agreed with that instead of making it sound like Banks is bad.

Yes reputable. GDE has been around since 2009. Banks has been around working on gas and diesels (both auto and marine) since the 1960s. They are thoroughly known in the auto industry, I don't think anyone would disagree with that. I can't believe you would even down play Banks in that regard, then use that as your basis to say GDE is better.
FYI: Here's a little achievement Banks did on a diesel motor... guess as you said, they were just "tricking" the computer ehh?!?!

Personally I don't care if it's illegal. To me, being "legal" is a great marketing point and nothing more. Folks, the EPA isn't coming for any of us so you have nothing to worry about! I don't even know how you could even get caught for tuning your car in your driveway and going about your business driving around. Last time I checked your car doesn't emit an audible beep to police that indicates you are running an illegal tune. I don't know, maybe it's a secret fast blinking brake light flash that only police dash cams can pick up (I'm kidding folks).

And as all the tune companies like to point out... their flashes leave no trace because you can re-flash to stock so who cares! Which by the way is a complete and total fallacy that isn't true. Every time a flash is performed it's tracked in 2 additional locations. I'll leave it at that. If you want more on this head over to the Jeep Gladiator Facebook page, post the question and wait for a few of the knowledgeable insiders to chime in.

Bottom line, Banks and GDE are two completely different tunes that fulfill two completely different expectations. I think both are good at what they do. Check out MR Tuning as well, unless you're afraid of the EPA.

@biodiesel do you work for GDE? Be honest.

I think we discussed that in the first 3 pages of this thread. I dont feel like rehashing this but i totally disagree with that statement.

Yup, it’s completely untrue. I really wish this would not be said. People need to fully understand the risk of a tune and voiding a motor warranty. That statement completely downplays the risk.

Agree 100%.

I never said banks was bad, but I did say that you can't compare the two. I don't know any knowledgeable EcoDiesel enthusiasts who recommends the Banks tune for the EcoDiesel.

Yes reputable. GDE has been around since 2009. Banks has been around working on gas and diesels (both auto and marine) since the 1960s. They are thoroughly known in the auto industry, I don't think anyone would disagree with that.

This thread isn't about the history of Gale Banks. This thread is about the Ecodiesel.

Again, you need to stick to the EcoDiesel for your talking points. The EcoDiesel leaves a count, but that is it. Counts don't mean anything. A dealer tech can have a flash fail and it will show as a count. Some people have more dealer flashes than others. My truck alone could have over 15 dealer flashes just in TSBs and recalls!

@biodiesel do you work for GDE? Be honest.

Nope, I'm just a fellow EcoDiesel enthusiast who is here to help others.

You can disagree. But to date, nobody has reported a warranty denial. I've talked to three service advisors and three diesel techs (from three different dealerships). One diesel tech said he's never had FCA/Stellantis request a flash count. Dealerships deal with the same problems and those problems are not related to tuned vehicles. I toggle between two dealers. Both have diesel techs that work fulltime on the EcoDiesel. Both dealerships recommend certain tunes and they are careful to ask the cutometer before making any flashes.

Could Stellantis lock their ECMs in the future? Absolutely. Could they record more than a flash count? Absolutely. So far, they haven't. I wonder why? Personally, I think FCA and Stellantis knows that tuning excites a certain fraction of the diesel community and that excitement helps promotes sales.

Stellantis reads these forums. They saw the number of people tuning the 2014 - 2019 EcoDiesel. But they still made the 2020+ ECM/PCM accessible to the aftermarket.
