Throttle lag

[Lee66]

2020 Ram 3500 6.7 HO Tradesmam
I have recently experienced what I am guessing is throttle lag and it got my attention quick, yesterday I was slowly going across traffic pulling out to a median and noticed fast traffic heading toward me. Gave it a little gas and after a second the truck accelerated causing me to tighten up a little and cut into the median quick. That is dangerous, I talked to a dealer and the mechanic said Ram is working on software fix for this. I then talked to another dealer for them to only say it is throttle lag.
I emailed Ram a few days ago, so far no response. Has anyone heard of Ram working in this?
It appears to more recognizable after the CP4 recall to CP3 replacement. It could be just me.
I do not drive the truck much, it is mainly used to pull my 5th wheel.


Beware- Also during acceleration if your not careful and you touch the brake with the left foot the truck will go into limp mode for a short time. Dealer confirmed this and said it apperas to be a safety setting. I have done it twice , my guess it is because of the throttle response at times.

You can't 2-foot most any modern vehicle thanks to Audi. They will all cut throttle input if you're in motion and touch the brake.

(It's a throwback joke to the one that started it all.)

DBW systems are all prone to throttle lag, seems more pronounced in an 8500lb truck.

Banks Pedal monster.....

Fixes all the lag. Makes everything feel SO MUCH better. Takes 5 min to install. It has 30 different settings, and honestly I keep it on number 4. Anything higher than this feels too sporty and causes the transmission to downshift much too quickly for my taste. I solely bought it just to get rid of the dead pedal or pedal lag and it does just that. No need to harp on the transmission or make the motor work harder than it needs to. Remember, this is not a transmission tune, like you get with a deleted truck. So your transmission will learn everything all over and the turbo kicks in within seconds of barely touching the pedal, but it takes a little getting used to for sure and takes about a week for the truck to relearn the new power curve it creates.

I put a JMS Pedalmax Terrain on my Power Wagon. Similar concept as what the Banks version is. Banks has some great reviews, but it takes up the obd port and I did not want to do that, so I ended up going with the Pedalmax. Mine has a dial where I can set it anywhere from stock to completely removing the throttle lag. And because it is the "terrain" version, I can also dial it the other way to give it more throttle lag if I want. I guess some people might want the negative settings to slow it down for rock crawling or something. I have yet to play with it off road which is my intended use for it.

Just took mine off last night because I have to take the truck in tomorrow for some warranty work and an oil change. Good god it sucks driving this truck without it now. It seems like it takes FOREVER for the turbo to spool and start providing power.

I temporarily put the truck in tow haul mode and that gets ride of the throttle lag.

I know this has been said before, but it bears repeating again: nothing you plug in can eliminate pedal lag. All the plug in devices are doing is amplifying the signal from the pedal, basically telling the truck you’ve pushed the pedal down further than you have. The computer isn’t going to respond to the change in signal any faster.

True, but is sure does make driving sooooo much better!

 

[Great White North Eh]

Yes I agree …especially if you are a toe-rool-into kind of driver, not a club foot masher type.

I just got a 24 3500 srw ho and put an edge ezx on it yesterday and it takes care of the lag. I also have a 2011 with h&s blackmaxx with a revmax tranny and while it's not as responsive as that it's a huge improvement vs stock. I'm running it on level 5 with throttle at 5 and the extra HP is easily noticeable and the lag is gone. The aisin seems to work better than it did stock and I put maybe 50 miles on it just driving around. For 650$ it gives you many options besides just making the pedal lag disappear. I'd highly recommend it.

Here's my truck

It’s a pressure box, so if that’s something you want to run then go for it… but it can’t take care of the lag, all it does is amplify your pedal input to make it feel more responsive.

 

[jacksquat]

Yeah I have the throttle on level 5 outta 6. The edge accomplished exactly what I wanted it to do until I can just delete it without spending 4k oh and when I tow I'll probably put it back to the stock settings because it worked fine with a trailer behind it the little bit I towed with it.

Or you can tune that throttle lag out if your at that point...

I installed this and it does make a difference., my truck is far more responsive and no lag. Not as good as a tune, but easy install and de-install when you have to take the truck into the dealer. No footprint either.

Another pressure box…..

While technically true, this comment comes off as silly-sounding from a person who has (obviously) not driven a 2020+ cummins with a throttle booster.

They do work as advertised. I repeat -- They absolutely deliver a more enjoyable driving experience.

OP -- Try the Edge EZX. That's the one I run. The box will also allow you to change the computer for tire size, has button recall (exhaust brake, front/rear warning cancel, etc), and a small bump in power (tune).

Truck drives fantastic with this setup. You couldnt pay me to remove it. It's that much better than stock.

Another pressure box…..

Meaning? Its not a device that accelerates the throttle response. It plugs inline into the MAF and fuel line connection. I have had a pedal box and this acts very differently in changing the air/fuel delivery. Its a decent alternative for us that cannot program our trucks. I get it that others may not be convinced, but I am simply sharing my experience with it.

Meaning it runs more rail pressure to get all of its results, which accelerates wear on the pump and injectors.

As long as CR’s have been out so have pressure boxes, and they’ve never been a preferred method of gaining performance.

The recommendation on pressure boxes is to remove them or not use them.

Understood and can't argue that, but it's the simplest fix for those of us who cant unlock and program.
