GDE is back and making EPA compliant tune!

[biodiesel]

Why they don't offer it now is anybody's guess. Maybe he wants to get his feet in the water with tuning these Gen 3s first, so to speak, before he begins to put it into the hands of consumers all over the nation.

If I remember correctly, GDE has to rely on third party sources to go with the handheld device which is time consuming. So instead of delaying the tune for another year or two, he's trying to get what he can to market.

Here's more information that goes with it:

“There is misconception about tuning in general. The ecm memory chip has 'code' and 'data' in it. Tuners change the data. Companies like Bosch, Siemens, Delphi and some OEMs write the code. This code contains all the logic flow like maps, curves, values, arrays, fids, etc. The calibrators then fill the code with data settings. Back when we were working for Chrysler directly, it was common for us calibrators to write 'feature requests' for new code to be implemented. We would lay out the flowcharts using simulink or similar, give it to Bosch and they implemented it in the next software release. Bosch would sell a platform software package and the OEMs personalized it with feature requests. It is also possible to use hardware in the loop along with an ASCET system to link into the software hooks Bosch bakes into the code. This allow one to write new code and test it immediately. Awesome hardware, but very costly.” - GDE

This is all very cool and interesting information. Thanks for sharing. However, I don't think anything in that paragraph addresses anything that's been an issue. There's nothing there that guys didn't already know.

He's probably got the tune on a laptop, and he probably connects the laptop to the PCM and flashes it. I don't understand why he can't either 1) mail the files to customers so we can flash it ourselves like tons of other tuning companies do or 2) provide a handheld device. I mean, it's been 24 months now since the Gen 3 engine debuted. It's not like it just came out last month.

Lots of flashing software and tools have license restrictions, things tied to VIN ect.. gone are the days you buy a piece of software that can be used multiple times across multiple vehicles without added fees. Software programmers figured out ways to get a bigger cut of the action by making tune flashes associate with vin numbers. Just like how Jscan works basically. Plus why would a Tuner who has put many hours into a product give away a tune file someone with flashing software can take and flash for his buddy for free.

That's the problem with software, once all the hardwork is done it's pretty easy to copy/steal without protections in place.

Forcing ECU mail in at least offers some level of control, someone with the right reader/writer can still pull the tune and bogart the work for their own profit, but that requires people/professionals with knowhow to do, and generally speaking the pro's seem to respect each other's work cause they don't want it to happen to them. Learning tuning is a pain in the ass and generally keeps the riff raff away.

Handheld units can likely be coded in a manner that makes it hard to pull the flash or flash multiple ecus without a fee. I bet you buy a handheld unit the tuner adds a vin to it, and now that handheld tuner only works with that vin, that way he is not giving away product for free.

There is a guy on here that is doing a magason SC and some tuning. He has files for his work but giving someone the files to use is no good cause they are encoded for the flashing tools he used and are tied to his VIN.

Is there a release schedule yet? I know CA folks had to wait longer.

I'm also wondering about this, and what gde expects the timeline to be for the handheld tuner option. Months? Years?

It would be best to contact GDE and get that information straight from the source.

Hah. Fair. Just emailed the support address.

That will be available the mid-November on our website. We have info on it at the link below, check it out. We have no timeline for a flash tool on the Gen3. It took those companies 4 years to have the flash tools working on Gen 2.

Well I was finally able to source a factory fresh PCM. The big question now is, who can I find to program it to my truck next week?

My buddy at an independent shop says he can do it, but I am a little skeptical. I'm not sure any shops outside of Jeep dealers have capability to unlock PCMs and clone them. We'll see!!

Just had Keith and Mat from Green Diesel Engineering tune both my engine and transmission on my 2021 JT gladiator rubicon diesel. It was an early tune. Drove 10 hours from NY to Michigan. I was getting 20 mpg now getting 23. I have 37 tires with 3 inch lift and bed rack with hard shell tent so stock was 29 mpg dropped to 20 after lift now 23 mpg. They took that oil pump noise away when shut off engine. Much more power and torque. Just a different better beast now. Mat said transmission tune delivers the most change in power. Keith said only uses high pressure EGR when starts cold until warm up then only uses clean low pressure EGR. They said I could go 10 even 15000 miles between oil changes but said stay with 10000 mile oil changes. Oil will be cleaner. It’s almost like the stock tune was restricting the engine. 1000 miles regens roughly. Drove home 10 hours. Better gas mileage. Even sounds better. Mat said stock tune sometimes quiet sometimes loud. GDE tune now always diesel sounding. It’s great. I strongly recommend it

This may have been discussed before, but how does a tune like this affect factory warranty?

Was it $1,100 for engine and trans both, or did they charge extra for the trans tuning?

I've never heard of an EcoDiesel owner being denied warranty due to a tune, but it is possible. Generally speaking, the tune isn't going to cause premature failure, so it hasn't been an issue. In most cases, the dealer has no clue you have a tune. Most of us switch back to the OE tune for warranty work.

Great Job! About what speed do you travel to achieve the 23mpg? I am able to get 30mpg going 70mph hwy, but doing 80-85 takes a huge hit to about 26mpg.
