News on a tune?

[J-Cooz]

Saw the video. That sucks about the GDE. I've watched your videos since before I even had my ecodiesel and appreciate your feedback. I was leaning towards it but now I think I'm just going to stay stock.

I haven't had the timing cover leak and have almost 50k km on my truck.

Best of luck with the Toyota. Looking forward to seeing the mods you do.

The PCM and TCM work in tandem. The truck still shifted like **** 1-2 and 2-3 even with the stock trans tune, although it was better. With both installed it took all the joy out of the truck. I have no idea how there are people who overlook this and act like theirs drives just fine with this tune. Shifting a diesel at 3,000 RPM under light throttle is a joke. Shifting it at 2,500 RPM is a joke. Locking the TC in a McD's parking lot is a joke. Holding 2nd gear to 25 MPH under light throttle is a joke. This is not OK, and they need to fix it. But.....that isn't why I'm selling mine.

DEF usage increased quite a bit from what I could see. I went from over half tank to having to refill the tank in less than two weeks. I was hoping that was a fluke but I saw others comment on increased DEF usage also.

The timing cover leak that's rampant on these EcoDiesels has nothing to do with the tune. Totally separate issues.
It's ridiculous that they still have the issue. My two were built 18 months apart and had the same issue. And I know guys were having this issue long before the Gen 3 engine debuted. It's just ridiculous that they can't get this solved on the assembly line.

I kept most of my mods. Will resell for $$$. Dealership kept the wheels and tires and bed cover but gave me $1,000 additional for those on top of their trade offer which was already surprisingly good. So I'm not worried about any of that. The only thing that stings a little is the tune. If the person who buys the truck contacts me, I'm going to offer to sell it to them for a deal to recoup most of that money. THIS would be the advantage of the Banks Derringer. It could have been resold to anybody with a diesel.

Or, if anybody here can figure out how to make the VIN in this PCM match yours so you can use this tuned PCM in your truck, I'll cut you a sweet deal on it.

As much as I loved my Gladiator EcoDiesel, I strangely feel at peace with this. The Tundra is SO simple and inexpensive compared to the EcoDiesel. It's saving me a lot of money already AND I don't have any fears of breakdowns or CELs looming over my head.

Thanks for the response. I’m hoping I don’t have any of those oil leak issues, but who knows. I’m going to call GDE on Monday since tomorrow’s a holiday and talk to them about what you expressed to see what they say.
As far as making the PCM work with another truck, only 2 things need to be done with alfaobd:
1) Get a data dump, note all the injector codes, then plug them into the new PCM with the old injector codes.
2) Change the VIN in the setting for VIN.

What do you think they're going to say? "Yeah, we realize the trans shifting is harsh and unpleasant, but we had to do that to hit EPA targets for approval." No they'll probably say exactly what they told people on the Ram1500Diesel forum, that I'm the only person who doesn't like it (even though people have complained about it even with the old Gen 2 EPA compliant tune).

I know guys could do that to the PCM with the Gen 2 engines, but will it work on Gen 3 with the new security?

I never assume anything until I ask. There’s no special new protocols for writing to our PCM’s, it’s just a SGW and we’re good to go. That being said, after you mentioned the Derringer, I looked into it and am liking what I see so I just ordered one.

 

[Daverous]

Okay, have to drop this in since several people are viewing this thread with questions and concerns. After reading the last several posts I decided to make a quick video a few minutes ago. Truck has been parked since Saturday. It also has the same GDE engine AND trans tune in question currently installed. We both drove to Detroit within a couple days of each other. I'm not posting it to refute what wxman is saying, I'm simply putting my personal experience up for view. Granted it is a little warm tonight at 54 degrees. I'll take another run out when the weather drops and record it for inquiring minds.

 

[J-Cooz]

Interesting..looks like pretty normal shift logic there.

Dave are you happy with the tune?

I'd say about 95%. I will vouch for the lock up being a bit jerky in stop and go traffic. I was locked into about an hours worth heading down i75 last week and about 30 minutes in it started to really sink in and bug me. This was between 3 and 7mph.
The increased Def usage is a bit of a bummer but on the highway not towing it hasn't been very noticeable. I'm sure it would hurt more under heavier load.
Lastly I really wish we could still flip off the egr. That's more of a peace of mind thing for me. No clue to what degree it would help long term. I only know the previous hot tune intakes looked mighty clean with it off.

That thing looks like an expensive pedal commander. Not sure how they’re modifying mapping, but I wouldn’t trust it without talking extensively with them first. This concept isn’t new though, and the hemi crowd has a version of this called the pulsar. I just wonder why no one else is doing it.

Nah, it's definitely not an expensive pedal commander. If you look at the picture it clearly says "FUEL" on one of the lines so to me it looks like it plugs in under the hood to the fuel feed signal and something else like the Banks Derringer. Also it is my impression that the PC does not increase HP and AGdiesel claims +45 HP. So it's not a reflash PCM and it's not a PC type of throttle booster. Also I emailed them and asked if I brought my truck to them and they installed it could they put it on their dyno and test it. They responded that they'd be happy to run a dyno profile. My guess is that they haven't had a 2022 ecodiesel to try it on, so I don't know how well it's tested out on anything this new. Maybe it's a rip off. Don't know. I just wanted to know if anybody has any experience with this company and their products and claims. Since it's an agricultural based company it's probably a little under the radar for automotive performance stuff. Thanks for your feedback.

I must not have made the connection clear enough, so what I was saying is it’s like a pedal commander in the fact that it modifies signals going to the PCM. I just ordered the Derringer as Banks is well proven and reliable.

 

[reddog]

OK. So the PC only connects to the throttle pedal to change the throttle sensitivity signal profile. That's all a throttle booster does. No where under the hood to interact with fuel delivery system or EGR or turbo profile. I'm just trying to understand the different types of performance approaches. Does your Banks unit connect between the ECM and the fuel delivery system and MAP? My understanding is that the Derringer does not affect the ECM programming, it just reconfigures the engine's electronics' reaction to the ECM or PCM signals that it receives. By doing this (and probably a few other things) it increases fuel and air delivery and therefore HP and torque. So it connects to the Fuel Pressure Switch and the MAP sensor to achieve this. I think I have this correct, maybe not. I read thru the AGdiesel PDF for installation and that is exactly how theirs is deployed ... fuel pressure switch and MAP and then there is a 4 position dial switch that I assume allows you to dial in the performance profile that you want. Below is an excerpt description of the unit.
" The 20240 Performance Module fits 3.0L RAM EcoDiesel trucks and Jeeps from 2020-2021. This diesel performance module is designed for fuel economy with up to 30% increase in hp and fuel savings up to 10%-20%. Adjustable with a four position switch you can adjust the power on the fly, Stock, +15 HP 30 HP, & +45 HP. The module doesn’t flash the ECM, instead it receives the data from the ECM, optimizes the signal to the engine improving the fuel efficiency and power. These savings ensure a quick return on investment so you can enjoy greater efficiency and less cost. Plug-and-play connectivity means there’s no need to cut, splice or modify engine wiring. All Ag Diesel Solutions modules are Made in the U.S.A." Don't know but it reads very similar to the Derringer and is also made in the USA. Maybe it's a clone or copy but it is Definitely more than a throttle pedal signal booster. Howevery I am not a professional mechanic and have never played one on TV. I hope you love your Derringer. Can't wait to read your review of it.

Sounds like you’re understanding correctly. I like the Derringer because it communicates with the obd system, which in theory should make the system safer. Banks are the only ones I know that are doing that at this point.

All this talk about in-line tuners versus PCM flashes makes me wonder how good PPEI’s tune is. They use HP tuners and an obd flash module, so no need to send the PCM in for a flash.

Do you miss your Canadian tune compared to the GDE? I have really enjoyed my stage 2 Canadian tune so far. My DEF usage has been 0 for two months haha

Good question. I'm still working on a few things in the background related to that. I hope to offer an honest benefits comparison at some point in the future. Just taking longer than expected. I want to be entirely fair to all parties and I do think in the end there will be benefits to each option.

There you go. 11 MPH before it would come out of 1st gear. Then almost 2,500 RPM to get the 2-3 shift to happen. And that's on an abnormally warm start for this time of year. When it's 20 degrees outside yours would be exactly like mine.

I guess some people just don't mind it. To me it's annoying as hell. I think the TC lockup at low speed is the worst part though. That's where the bobble head action of passengers happens.

 

[Daverous]

I've driven mine in lower temperatures. It performs exactly the same as the video. 2300 is a far cry from 3k and I do not have the lurching you described in my normal driving. I do not encounter the restart throttle issues you've described either. I will concede the stuck in traffic point at the stated speeds. That's a very specific set of circumstances, not an every day occurance for me. I do not encounter it in my standard city stop and go driving.
Your experience is yours, not mine. Saying others "just don't mind it" or that others don't notice implies that I'm experiencing the same things you've complained about, and that's just not accurate.
Does the new tune do things I don't like? Sure, a few I listed. My experience is that the trade off is more than worth the gains.

Enjoy your new truck.

Just saw you’re pretty popular on jeepgladiatorforum. They have some interesting threads over there.

That forum was amazing a year or two ago. Lots of mature guys sharing great technical information. It's still a pretty good forum but lately we're seeing a lot more of the riff raff showing up as more and more Gladiators are sold and those people are joining the group. I still visit it daily but honestly it's a shell of what it used to be. At least if you're a more technical old school guy like me.

Based on what I've read, I'm on the fence about the GDE tune. I'd love to have a chance to try it...and then decide. But not with the shipment time of my ECU back and forth twice for that to happen.

Sure wish I knew somebody with the Wi-Tech software so I could get the VIN changed in this PCM I've got. It's a new PCM with GDE tune already installed just sitting in a box on a shelf in the garage. Fits Ram and Jeep. I could make somebody a great deal on it, and then you'd immediately have a tuned PCM and a stock PCM both. But that dang VIN would need to be changed....
