At least for us, this was always causing issues with the power inverter in our test vehicle beeping at us for insufficient voltage. Also on our vehicle the battery state of charge was always hovering in the 80-84% range.

By switching this function off, the state of charge stays around 90-93% and we've seen no fuel economy degradation as a result. Also, no more unhappy electrical devices in the car either.

Re: green diesel engineering tune

I have a Limited with hill descent/ascent control and select-speed. The order process asks about Overlands and Summits with those features, but doesn't ask about Limiteds with those features.

Is this an oversight or is there something different when an Overland/Summit has these features versus a Limited?

Re: green diesel engineering tune

After the purchase we need the following WK vehicle information to properly setup the ecm:

1. VIN
2. Injector code picture (bar code located on front of the engine, top left as viewed from the front of vehicle, see attached picture)
3. Standard cruise or adaptive cruise
5. Hill decent control enabled
6. Select speed equipped

Thanks, GDE

Re: green diesel engineering tune

Since I've probably read every post on every relevant forum regarding this tune and have been very appreciative to those who have shared their thoughts and opinions, I wanted to share my initial thoughts on the GDE tune which I finally purchased last week and installed this weekend.

First off, I have the 2014 Overland 4x4 with just over 15,500 miles. I dealt with the P20EE MIL & SCR replacement at around 11,000 miles and while I've had no further issues, I've since been uneasy about the long-term viability of the vehicle due to the impacts of the emission control systems. The GDE tune improvements to the overall engine and exhaust management was very attractive to me in addition to the MPG improvements and added performance but it took me about 2 months of reading and researching to finally pull the trigger. After a weekend with the tune, I'm very happy I did.

Install: Regarding actually installing the tune, I have to emphasize that getting to the bottom bolt on the ECM mounting plate is a pain. There is no room to work around it, so be prepared to get a bit frustrated. On the RAMs, GDE instructs you to remove a handful of parts to more easily access the ECM, but that's not the case on the Jeeps so you really have to work at it. I found that using my very small 1/4 ratchet with a short extension and the 8mm socket was the best tool to break the bolt loose, and then as GDE suggest just use your fingers to back out. Once that's taken care of, the rest of the install was straightforward.

Only minor issue I had was that my DEF gauge did not reset to the proper level as some others have mentioned. I was sitting right at 1/4 tank prior to the install and I'm reading over 1/2, but I'm going to pick up 2.5 gallons today to add which should trigger the sensors again. I'll report back on that issue.

Initial Driving Impressions: As others have reported, I notice a slight change in engine sound to a slightly deeper, throatier note which for me is a positive. Initial acceleration is improved, but I think my expectations were set a bit too high based on other posts and I was expecting it to respond like my '04 V8 GC which just jumped off the line. That said, it's still a turbo diesel so it's never going to act quite like a gas engine, and again it's a noticeable improvement so that's a positive.

On the flip side, I had underestimated the overall acceleration improvement across the board which is fantastic. Merging onto the highway is a blast now and you really feel the engine pulling through each gear. Also, I LOVE the fact that I can now sit in 8th gear at highway speed from 50 mph on, and accelerate up to 80 mph without a downshift.

Driving around town or in traffic is much better as well as the tranny doesn't have to search for gears as often since there is more power and torque available at any given time so as many have pointed out, you just feel more confident in the response time. I also don't feel the need to shift into Sport mode, or at least disable ECO mode as often now since the engine feels like it's a better match for the tranny now.

Fuel Economy: Since I purchased the vehicle I've tracked every single tank of fuel in Excel to "hand calc" every tank and also estimate my payback and savings over the HEMI, so I'll have a perfect baseline to compare to moving forward. I'm only about 100 miles into the tune and I've been "testing" the acceleration regularly, so I'll report back periodically as I rack up some more normal miles. I can tell you that prior to the tune, my average fuel economy since inception (about 15.5K miles) is right around 23.5 mpg, with my best tank at 27.2 mpg and my worst at 19.8mpg. My daily commute is about 15 miles each way in mostly in stop and go traffic so I've definitely seen lower mpgs than some other owners, but I'm excited to see what the GDE tune does for me moving forward.

Concerns: So far the only issue that slightly concerns me is that I've noticed an engine shudder during shut-down that wasn't there before. Nothing too violent, but you do get a little extra shake in the cabin during the last stroke of the engine. Probably a non-issue but something I'll keep an eye on to be sure. When compared to my old F350 Power Stroke this thing is still a Swiss watch, but I'm hyper-sensitive as I'm sure many others are.

I'll continue to report back as I log some miles with the tune, but if you decided to skip over the novel of details above and want my bottom line, all I can say is based on my initial impressions I'm another happy and satisfied GDE customer and would recommend that anyone on the fence make the purchase. You won't be disappointed.

Re: green diesel engineering tune

I'm interested to see in a year or two if any GDE customers get a P20EE code? I don't think they will, regardless of which year/version of catalyst is present but that's my gut instinct.

I second this. It's one of the biggest reasons I purchased it. Mine threw P20EE once before my purchase. The GDE guys said the tune should resolve that. I'm sure there might be one offs here and there for some (anything massed produced has a failure percentage), but it should definitely improve reliability and longevity on the whole.

It is technically impossible on a number of levels to set the P20EE SCR Cat Efficiency fault with the GDE tune.

Re: green diesel engineering tune

Anyone install the new U-Connect software after Hot Tune ECU flash to prevent our Jeep's from being bricked by Hackers? Just read about it and don't want to mess up anything with my Hot Tune. Don't want the Jeep being taken over either. Thanks.

I installed the update to the U-Connect software yesterday after installing the GDE tune over the weekend with no issues, but we're really talking about two separate issues. I'm sure GDE can opine with more technical details but the hack isn't able to access or alter the ECM, it accesses things such as the throttle inputs, AC controls, etc, and the Uconnect updates have no connection to ECM programming so I can't imagine any issues there.

On a side note, if hackers were able to access and alter the ECM, GDE should hire them and they could eliminate the need for the ECM swap, and the Flash Tool, and simply remotely log in and tune our vehicles from Detroit. Scary, but possible I'm sure.

Re: green diesel engineering tune

Chad, the unconnect update is on,y for the radio, nav, and remote available controls. That update has nothing to do with the ECU which can only be accessed through the OBD port.

Good to know thanks. I'll update the U-Connect then.
