Soooo, just like everyone else has stated, this update is unsafe and sucks ass. I have complained to FCA and they say take it back to the dealership. Call dealership, make another appointment for what, for them to tell me we checked everything and nothing is wrong.

Hate lawsuits but this shit is getting ridiculous. Truck feels like I have a Prius! Minivan I had for a rental had more get up than this!

What will FCA do about this? Need more complaints? They flap jacked lied and said it would have no affect, but the throttle response is terrible and MPGs are about 2-3 less.

Need the deadline for first owners to be over so I can order the GDE. Is there anyway that the tune can be a tax write off since I use my truck for work?

Bringing the truck back to the dealership to get looked at because of the shit software. I know they won’t find anything ‘wrong’ with it as it just plain sucks. We shall see

Well, nothing wrong of course.

Their response, “you need to drive the truck a 100 miles or more, the truck needs to learn the way you drive again.” I said, excuse me? Let her try to explain then I left. I had driven over 300 throughout the week.

Thought I heard them all, but nope!

I don't want to get into an argument about how your truck is performing now compared to before the AEM update. My point is that your comment "just like everyone else has stated......" is not a correct characterization of the facts. While many have complained many others do not see a change or see an improvement. There seems to be a binary outcome of 'it is crap" or "no significant change except holding gears a bit longer onthe upshift." How the perception of the results can be so different is puzzling. Perhaps the key is the word 'perception" since I don't recall seeing any before and after actual performance measurements.

All the best,

I too am having serious lag in acceleration until the engine is up to temp. My service adviser told me they know about the problem and had another ED in their shop troubleshooting the issue. No sense in me leaving mine there too. I opened a STAR case so at least my issues are on the record. I live in Cali, so will be trying the pedal commander. I'm relatively happy with how the truck drives once all the levels are up.

FCA just went through an expensive law suit that resulted in the crappy neutering AEM tune. My bet is they have washed their hands and are moving on. Thankfully, there are aftermarket solutions to the problem. So, get the AEM, the extended warranty, and the $3075. Take some of that money and obtain Pedal Commander or GDE, lag problem solved.

For those in California who are prohibited from seeking aftermarket solutions, I recommend to not get the AEM at all.

Californians can't "not get the AEM". California is requiring proof of the AEM before they will re-register the vehicle.
We do have the option of SFT's tunes which I have found to be the perfect solution.

Let us know how you like it. I’m in San Diego too and the lag is crazy.

After AEM at low speed does not accelerate properly, have to kick it down to get it to go, also I turn off the traction control.

My service dpt reports no joy from FCA.

GDE becoming more likely.

Good point howie12. So why don't we conduct a poll to see if forum users are seeing an impact on truck behaviour or performance? Something like a negative, neutral, positive poll. Perhaps someone web smarter than me could do this?

if the $3075 is not driving you bananas ,
I would definitely wait for the developments on this "hit and miss AEM update ".
at least ask your dealer's diesel tech , if he did many AEM , and he Aced them all ,,,,, if he can be trusted .

Nothing to argue about, just the truck is not the same at all. There aren’t too many threads on here with people saying it hasn’t changed at all. I haven’t towed anything with it yet so haven’t seen how it effects the truck in that regard.

What improvements have people seen? Are there different versions of the re-flash?

I had my software update about 2000 miles ago. Since then I drove a 1200 mile trip and other than when the engine is still warming up, below 175 F, I have noticed a slight difference in shifting but not acceleration. To resolve what I call a
slower or sluggish shift in the lower gears, I set the tow/haul option and that gets me up to speed with a little more boost. I'm anxious to see if long term my fuel economy changes. Can't tell from the long trip as I had 2 Kayaks creating a little wind drag.
Will update on my next long trip which will be in about 2 weeks.

Heading on a 6 hour drive today in which I normally get 24-26mpg, will see how this updated software does. So far, going 69 and it’s only getting 21-22mpg, normally around 27mpg at this speed

Hello, I contacted FCA today and informed of the slow acceleration issue. At first I did not notice a big difference but after driving for three weeks it is definitely very different and a safety concern. Below is the response I received with the email I sent.

Hello,

I apologize that you are experiencing issues with your vehicle. Please contact the dealer to make an appointment for diagnosis.

Hello,
I am seeking advice and do not know who to contact at FCA. Upon completion of the AEM software update I have noticed a fairly significant issue with acceleration from a complete stop. The vehicle starts to move slowly but the engine can take 1 - 3 seconds to recognize the pedal is depressed if attempting to accelerate quicker. It is even noticed upon slow or average acceleration but less evident. It seems to be more pronounced when the engine is cold and improves once warmed up. Many others have noticed the same issue and posted complaints on different forums. I personally feel this software update created a safety concern for those owners as it changed the performance. This issue can lead the driver to enter traffic without proper acceleration response associated prior to the update. I have personally changed my driving habits but feel FCA should receive this feedback.
How should I formally inform FCA of this feedback.
Have you received other similar feedback?

I called 1800-992-1997 and opened a star case over the phone. The case manager is now in regular contact with me, albeit there is no solution yet. If my trucks lag causes me to get rear ended pulling out of my driveway on a foggy morning, I want my complaints to at least have been documented.

Same thing here. Took the truck back to the dealer (as the Rep. at FCA Chrysler suggested) and had a service tech drive the truck. He admitted openly that yes, there is a definite throttle lag in response to the pedal position. A lot of good it did as he wrote on the service work report - "TEST DROVE WITH CUSTOMER. ALSO TEST DROVE TWO OTHER ECODIESELS AND HAVE SAME RESPONSE ON THROTTLE. NO ABNORMAL OPERATION AT THIS TIME", CANNOT START STAR CASE UNLESS ABNORMAL OPERATION CAN BE DUPLICATED".
What a lying , two-faced, back-stabbing piece of s _ _ t! Don't tell me they don't know this is an issue. I believe corporate has told all dealerships to ignore this and admit no wrong in the hopes we will give up. I encourage everyone to contact this attorney once you have your settlement check and are having an issue with the new software.
