Additional Dead Pedal Info

[jhenderson]

I have learned to produce the dead pedal on command. Fortunately that also means I know how to avoid it and do so.*

Been on the fence about buying a New Ram, but this thread has me thinking seriously about not. Nothing like plunking down $60K for a new truck and then hating to drive it..

Ok here's the deal the D-max L5P is all new and Denso fuel system the Hero/Zero status is open, The 6.7 Scorpion Ford means you will need to deal with the Blue Oval on repairs and parts. Ram Cummins is still the long time owners all around best.... Both the Ford/and GM are V-8s its more in repairs cost regardless, just on the #s.
You won't be complaining on dead pedal when engine is dead..

After the last go around in the shop with my 2014 ram 3500 cab and chassis I started to notice if I stopped at a stop sign and then gave it some pedal it hesitates and acts like there is nothing there. I never noticed it before because the truck was in and out of the shop with other problems. I only notice it at stop and go situations and if I ease into the throttle it isn't so bad. Still like the truck for towing my living quarters horse trailer even if it likes to mess with me!

I have only noticed it in traffic, especially when trying to merge onto the highway. You get up to speed and start merging, just then the idiot a few car lengths in front of you (who is also supposed to be merging) hits his brakes hard. You are halfway in each lane, you need to brake and merge quicker to not hit the idiot then immediately fuel hard to not cause an accident behind you, but that last part doesn't happen and you are puckering the seat due to the dead pedal. Maybe this is not a common occurrence in some parts of the country but it is too common around here. It is easier to merge when traffic is nearly stopped. When it is moving at all, people leave little more than a car length between them for you merge into traffic (and they take that away, too, if they see you coming).

Has anyone noticed a relative difference in dead pedal response time when paddle (manual) shifting.*

 

[MJWenrich]

Since no one else responded, I will. I anticipate passing or entering traffic and downshift ahead of time. The lag is still there but if you ramp up rpm, it is not as noticeable. From a stop, not much you can do. Have to give extra clearance for traffic. Whatever you do, do not let off the pedal after shifting into second and expect to be able to accelerate without the long delay. Even my aftermarket device did little to help with that. But it did help with going from a stop. Very disappointing situation but learn to deal with it. RAM isn't going to do anything about it.

"RAM isn't going to do anything about it"

They may not, however, I'm kicking and screaming the entire way. I just filled out another survey with them yesterday and wasn't nice. I even posted a link to the Throttle Sensitivity booster by BD as proof positive they have a problem with engine hesitation/dead pedal (whatever they want to call it). My truck has been to the shop and my dealer is zero help, even stating they won't start a Star case even though Chrysler customer service requested they should. Hopefully a TSB will come about to improve this problem. I'm leaving the truck in the driveway and driving the Liberty CRD because it's so much snappier.

This has been a most interesting read....I recently purchased a 2017 Laramie Longhorn DRW 4x4 with 3.73's and have not noticed any "dead pedal" issues yet....but with my early '07 5.9 I had serious "dead pedal"! The interesting thing was that the dead pedal began immediately after having the transmission rebuilt with a Sun Coast kit! My diesel shop went through everything trying to figure it out and if I remember correctly....after changing out the TIPM(?) the problem disappeared! If anyone is interested, I can go back through my receipts and tell everything we changed out trying to solve the problem....don't know if my "dead pedal problem" is related in ANYWAY with the newer trucks or not?....but interesting....

Adding to my earlier thread, I do notice the dead pedal at other times, but without the pucker factor. Almost anytime when driving around town with minimal throttle, if I let off then put the throttle back to where it was, there is dead time. This is not a case of flooring it, letting off, then flooring it again. This is minimal throttle, let off, go back to minimal throttle.

Well, I'm happy to report my new Aisin equipped Ram 3500 has no dead pedal issue. Ramps right up quickly off the line...

Hope you guys get it sorted out...gotta be something simple.

 

[MJWenrich]

Maybe when you go in for service and they reflash your computer you can join our ranks. We hope not. If it were something simple it would have been solved over the last three years and numerous visits to the dealer. I have no expertise to say this but I think it's torque management and EPA. RAM wants a delay off the line to all that torque and EPA wants to limit emissions by limiting power. Why it does not occur on all of these trucks, so equipped, is the greater mystery for me. If yours does not have the delay then why do ours? Or why can't mine be set to your parameters? It just takes the joy out of owning one of these machines. Not only are they expensive but now I am keeping my 04 which adds to the overall costs.

Have someone that thinks it is real bad, and I believe it will be the same in any truck he drives.

Just a FYI and not that any of you care but Nissan released an update to the ECU that resolves the dead pedal on the Cummins/Aisin Titan XD. Most people with this truck experienced the same type throttle lag as the RAM. Just goes to show ya that FCA is not working real hard to resolve your issues. How many years has this been going on now?

Hyundai still haven't done anything about dead pedal on my genesis with Aisin trans

Link to ECU update for Nissan?

 

[8_1gasser]

I don't have a link but it's NTB17061 here's a summary.



Subject: SB 2016-2017 Titan XD; Delay with Re-Acceleration
Summary of NTB17061:
IF YOU CONFIRM Re-acceleration delay as follows: - Driving at a moderate steady speed, then - Reduce accelerator position to slow down, then - Increase accelerator position to bring the vehicle back to the previous speed, then - There is a delay/hesitation before the vehicle begins to accelerate. ACTION 1. Save Computer Data with CONSULT-III plus (C-III plus). 2. At step 6 of the reprogramming procedure, confirm this bulletin applies to the vehicle you are working on. 3. If this bulletinapplies, continue with reprogramming procedure. 4. Write Saved Data with CONSULT-III plus. See this bulletin for further detail.

Here is a post from a Nissan forum. Maybe FCA can get Nissan to rewrite the RAM ECM/ECU code for them.

"I got TSB 17061 done yesterday specifically for the dead peddle issue, my truck was the first one my dealer has done with the update.

Overall the truck drives WAY better!!! This is an ECU update not a TCM update, so with that said you can feel when driving the truck in all scenarios they re-worked the TQ Management calibrations and probably some other stuff to help eliminate the dead peddle issue.

The biggest problems I had with dead peddle was in two scenario's, 1 - from a dead stop where you could feel TQ Management limiting power below 1800rpm then bam came the power. 2- When making a right or left hand turn, having to slow down (not stop) to make the turn then getting back onto the gas hard there would be nothing there.

After this ECU update I can tell you that the issue is pretty much non-existent now, the truck will down shift much sooner without any fuss or delay to get you moving out of the way of traffic. The truck doesn't down sift fast (normal for any truck) so it's not an instant sports car type of hit but you can feel the truck responding to your peddle input now and starts working.

As far as a dead stop, you can still feel TQ Management below 1800rpm BUT you can tell they backed it off some and are allowing more power than before so that you're actually moving forward LOL and also it seems to rev faster out of that area quicker also which makes sense if they are allowing more power to push through it.

The other improvement I noticed was when on the freeway, to pass or just accelerate the truck is way more responsive and quick to down shift. I never really felt this was a "big" issue but it's much better now!!

So far I don't have any complaints at all, the truck is much more responsive and fun to drive."

 

[8_1gasser]

I don't have many miles on mine since the update but I completely agree with those statements. There's no doubt that the update improves drivability across the board. Maybe FCA will get off they're assets and do something.

Patiently waiting for Fiat/Ram's response......

Someone on here has got to have some sort of contact with them

 

[ProLean]

Still thinking I'm going to get the BD Throttle Sensitivity Booster in the meantime whilst RAM "thinks" about doing something about the issue. I hate having to drive around this flaw in an otherwise fantastic truck!
