Thanks for clarifying. I certainly misunderstood.
Just received a letter from FCA acknowledging the lag after the aem update. It also said they updated the software in December 2019 to correct the issue. Wondering if anyone had the update done since then and if they still feel the acceleration issues all of us have?
I spoke with a person at FMC not FCM. Sorry for the mistake.For all that read this. I agree the letter was poorly written. Yesterday (1/17/2020) I spoke with an FCM person in the recall department. After several minutes of checking she informed me that the purpose of the letter was to alert us 2014-2016 owners that a second software upgrade has been developed (I guess to help prevent another lawsuit). She said that we will be notified by an official recall letter sometime in the near future. She couldn't give me a date certain.
Also, my truck lags and I've almost been in 3 accidents because of it. You think you have time to make a turn, and you don't because the truck won't accellerate much when it is cold. It never had this problem until after the AEM.
I'm interested in how you pursued this at the dealership. I've called multiple dealers in my area and none of them had any clue about this and said there wouldn't be anything they could do until they receive the patch. How did the dealership go about finding the software patch and how did they convince you that the patch actually addresses this particular issue and not something else altogether? Thanks!Got the latest update today I will let you know if it helped after cold start in the morning. P.S. Dealer knew nothing about it after much discussion and 2.5 hours finely got the new update. Said it wasn't in the system yet.
Just got the new update yesterday and it seems to have fixed the lag. Had to argue for over an hour to get them to do it. There computer didnt show a new update. Got them to hook it up and the update showed up. So far 2 MPG increase in MPG and no lag.Also, my truck lags and I've almost been in 3 accidents because of it.

Got the update Yesterday it wasn't in the system yet but they hooked my truck up and there it was. 2.5 hours later mileage is up and two cold starts and no lag. Best of LuckFor all that read this.

How is your truck doing after the update?Just got my letter today... My AEM isn’t scheduled until the 25th... I am also expecting my new HDDS ECU in the mail tomorrow. Thinking of swapping the ECU for the week in between just to see the before and after performance of the STOCK vs HDDS then what the AEM vs HDDS. I’ve included my letter

No I didn’t get any paperwork. I was told it was to new to invoice.Do you know what the PCM/TCM numbers are for the new update? I had the AEM done on 1/27 but guessing its the old version given the lag. My invoice shows updates to 68307635AI (from AC) and 51208927AJ (from AF) (on a 2014 Jeep, not a Ram).
