Heads Up possible dead pedal fix.

[SnoKing]

Well, with the dead pedal issues getting posted in other threads, I thought I would bring this back to one of the original dead pedal threads.

After what was post in the other threads I tried romping on the throttle at various speeds to see if I could create the issue on my 2015 3500 SRW Laramie. Nothing! Hit the pedal and it goes!

seems strange that some trucks have this and some do not. Do we need to start a spread sheet of the configurations of trucks that have the issue? Maybe we can narrow it to a particular configuration of given trucks. SNOKING

Thanks for bringing the thread back, I haven't thought about it for awhile. I have to keep my RPM @ 1500 under different driving conditions, due to the pinging when @ 1100RPM at cruising speeds under 50 MPH, that the ECM/TCM allows my CTD to run at on its own, and have not experianced the dead pedal since. Part of the issue I believe is just that, in that the ECM/TCM has to think as well as the time it takes to change to the proper gear. This is, IMHO, an issue with the 3:42 rear diff, mostly due to the low RPM's that the truck can run at in a higher gear. What is your Diff ratio SNOKING?

 

[SnoKing]

Like all SRW new RAMs they are 3:42's. I have no issue with them. I also played around again with Tow/Haul, which in normal driving seem to put me in one gear lower pretty much across the board. I live in a small community surrounded by farm lands. Speed limits are 50 on a lot of the roads and 55 on a state highway. Coming for 14 years of 4:10's in the 2001.5, it is a nice change for me. In a few weeks we will be off to Arizona towing the trailer at around 21K combined and I will have a extended chance to see how the long legged girl "Cherry" does on mountain passes and extended hours on the road.

Oh ya, I forgot about the SRW with the 3:42, but I also believe the Aisin is better capable, as well as programed beter than the 68rfe.

The device has been around for over 1 year, While they hoot and ha en did they check the rail hang that module produces? and why would anyone want to drop $$$ on any device that can be overcome by just pushing farther on the go pedal. Why do people buy a truck that weights in at over 7800lbs and expect to move like a 3200lbs Dodge Charger with a Hemi.

Both My 13/14 get right up and move, maybe removing the fuel restrictors in the rail had something to do with it....

TC: I'm pretty sure you have read all the postings on the forum quite awhile back about the engine lag and the dead pedal problems. If you haven't experienced either of these, they are scary. But more importantly, they are dangerous. Driving your truck empty, hauling or pulling something and you are at a stop sign, waiting to pull out into traffic. Step on the pedal and the truck will move forward a foot or two and then it's if you just lost all power to the engine. Pulling onto a freeway, heavy traffic and you want to get into the flow. Same thing. Press the pedal and it's like no power. I was towing my travel trailer, one car behind me, one slow driver in front of me. Had a chance to pass the slow one. Got right along side the slow driver and the engine acted like it lost power (engine lag). The guy behind me was passing the slow driver. I had to back off the pedal, hit the brakes and pulled back in behind the slow driver. The guy who was also passing almost rear ended me.

With this dead pedal, there have been more times than I can count when I have started to pull out into traffic, seen other vehicles coming in my direction but figured there was enough distance and was safe enough to go. Step on the pedal, truck moved and then, as I stated above, it was as if there wasn't enough power to move the truck. Only last for a few seconds but long enough to almost be rear ended. Chrysler refused to acknowledge this was happening. The NTSB received many complaints but nothing was done.

I brought the dead pedal and engine lag issue up with my service manager about a month ago. Was told there was nothing that could be done. So I'm going to check into this new system to get all the information I can on it. I don't want to smoke the back tires up or put an undo strain on the engine or torque converter, etc. I just want to be able to step on the pedal and feel very comfortable that I will not cause a wreck. I do have a 2014 Laramie with only 6,480 miles on it. Part of the reason for the low mileage is due to me not trusting the truck enough for me to be driving it a lot. My DD is a 2014 Wrangler Rubicon and I do drive the heck out of that.

If this device is something that will "sling shot" you from a dead stop then it's not what I am looking for.

 

[Bill]

So how many people report this on www.safercar.gov. If everyone with the problem reported as a safety issue, then the government would make RAM fix it. SNOKING

I reported it to safecar and also to the National Traffic Safety Board ~ I posted it so many times that I received an e-mail stating that hundreds of Dodge truck owners across the U.S. were doing the same thing so there was no further reason for me to contact them. I called Chrysler so many times that I think they installed a "Red phone" that had just my phone number on it and refused to answer it. I did manage a few times to get the customer support person that answers the phone to transfer me to a Chrysler service Tech. Like trying to talk to a brick wall. I had the truck to my service department so many times that finally, one day I just lost my temper. That's when the General Manager heard me screaming at the service manager and mechanics. So I was informed to immediately get into my truck, leave the entire dealership property and to never bring the truck, my Jeep or the wife's new Avalon back for any reason. Only recourse was to take it over a mountain to another Chrysler dealer. Called to make an appointment and was yelled at by their service manager to NEVER bring any of my F****** vehicles to his department. The local General Manager which I found out later had called and warned him that I was his biggest nightmare and to not service my vehicles.

Normally I would never bow down to anybody but after three months and numerous problems with all three vehicles, I went to the General Manager and ate crow. I was then allowed to have my vehicles serviced again but thoroughly WARNED if anybody complained about me, I would never, ever be allowed to come back. Called Chrysler over this. Managers of dealerships do have the authority to ban anybody from their dealerships because they are considered a seperate, independant business. Checked that out with my attorney and it is correct.

My 2015 2500 has the dead pedal, pretty bad IMO. I find it to be quite irritating, dangerous at times, especially when I have a 10k # trailer on the back. If for what ever reason I need to lift real quick, then get back on again there is nothing there, will sit several seconds before the power comes back.

I'd like to hear more about the REAL root of the issue. Is it a rail problem, or is it something programmed into the computer? Is the torque management a computer issue as well?

I love this truck, tows MUCH better than my 2003 HO, but would be perfect if I could eliminate the dead pedal. I don't need a programmer with more power, just want to eliminate an issue Chrysler should have taken care of in the first place.

My truck has this same problem, but maybe it's because I'm an impatient idiot here in CA as was stated in the ridiculous post earlier in this thread. I also notice I lose pedal when I most need it to power through turns. There is one freeway off ramp on my commute that dips down into a pretty tight turn at the bottom, if I need some throttle to merge into traffic, it won't be there. Until I found this dead pedal thread, I was thinking the issue was caused by the stability control system because of how affected my truck is buy any type of corner forces. It's downright dangerous. The quick lift off the throttle, and then back on again issue stated above has left me in harms way more than once as well.

 

[GCecchetto]

I forgot to mention, that if I turn off the stability control in my truck, it makes a significant improvement in the dead pedal issue, even just pulling off of a stop light. The pedal is much more responsive.

 

[MJWenrich]

Ditto to what Bill wrote the bottom of page 3 and I tried turning off the stability control but it did not help mine. It is nice that someone else understands how severe this problem is rather than making light of it or implying that we are exaggerating. It's dangerous and RAM should fix this if it's just a programming error with "some" trucks. Sure has taken the joy out of a new truck for me.

Yes, I find it hyper annoying that some people imply that we are at fault due to poor driving technique or something just because their truck isn't one affected by this issue.

 

[TCDiesel]

ALL class IV and up trucks have the same TQ management. I"m glad I have 2 special trucks that preform as intended. If I had the dead pedal I would find away to resolved it or sell it and buy a manual trans, I certainly would not be annoyed to the point of inciting others to join My crusade, then be critical in the process.

I've been on ride along's , The habits of the driver is the Problem at times, The dart driving couple with both feet use or aggressive stopping to WOT then let off back on, this type of driving is consider to be normal to them and regardless of the facts they still want the truck to adapt to their habitual driving. The back off ,back on causes the truck to stumble.

So what the solution?

 

[SnoKing]

OK, I had to run up to Anacortes to visit my 100 year old neighbor who is in rehab. To set the stage a bit, we have had our 2015 to 10+ weeks and 4,000 miles and never noticed any delay in throttle response.

So on the way back home I start playing around and seeing if I could create anything! If is stepped down a bit on the throttle let up quickly and then right back on it, I could get a 1-2 second delay! I will play with this a little more on the way to Arizona with the trailer and then maybe document it with safercar.gov. In the mean time I will go back to my normal drive style that did not make this happen.

Where this becomes and issue is when something happens in front of you, like a multi car accident, that forces you into an emergency reaction where you have to lift very quickly and then get back on the throttle to evade out of control vehicles coming at you. This may sound far fetched to you folks living in the less populated states, but it's not uncommon at all here in Kalifornia where we have 52 million smartphone drunk idiots on the road. The long and short of it is.....when you need the truck to go, it needs to respond. You've all said these trucks will scoot, even those of you that feel those of us affected by this are at fault due to our driving style, so it isn't a matter of the truck have the get up and go, it's a matter of the computer telling it to do so.

 

[Newsa]

Some have claimed it is caused by 2 footed driving. I highly doubt it.

 

[TCDiesel]

GCecchetto, I see your point ,Think about it this ,You need boost and fuel to make power W/O soot, previous generation could dump fuel and smoke, NOT SO with 4 gens, the system must produce clean power couple that with the power these engines have down low will break shafts or cause jerk/bucking, So the delay allows the boost to be a fraction ahead of the fuel, once it lights they scoot. in reality it just feels like FOREVER but the delay is mandatory for many reason(s) .Yes both My Big Rams have this its call TQ management, My Ecodiesel does not have this and that little 3.0 spanks My big Rams when it comes to being quick The ED is 3.0 3.92 8-Speed Banks Bullet, Big Rams 3500 SRW 3.42 Aisin Stryker modded Pump/rail.

Then why does the g56 not have it?

Maybe when they don't turn the power up -

they don't turn the toque management up.

[TCDiesel]

You can't shift in a fraction of a second with a manual either. RPMS must Drop and raise when shifting. its build in TQ Management, couple that with clutch slipping.

So i'm guessing that based on what i'm hearing is the dead pedal comes from when it is searching for the correct passing gear?

Less Peak Torque = Less Torque Management?

Reasonable assertion.

I am perfectly fine settling with 200 more ft lbs of love than the legendary 12 valve.

I certainly don't need twice as many ft lbs as the 12 valve.

That 2016 with the Aisin is close to twice as much torque as the 12 valve. At least on paper.
