Hey John, You helped me out 2 years ago when I installed the EZLynk 2 on my 21 2500. I took a hiatus and had a TRX for the past year, but regretted trading my red 2500 Limited for it. So I am back with a 23 Blue limited and just got eh EZLynk 3. Got it plugged in and discovered a nasty change RAM made, in that I can no longer remove or exceed the factory speed limiter. I can do other things such as TPMS thresholds and fog light dropout, but no more altering the speed limiter. I spoke with Duramaxtuner and they are working on tuning programs for the 23s, since RAM changed some things in the PCM.
My question is what can you share about how to get the speed limiter removed? Even if I use another product?
Thanks!
Ziggy, Congrats on your new ride.
Here's the Alfa settings:
Truck Speed - Maximum:
Car Model> Ram 3500> Function> Engine> Select Control Unit>
Diesel Cummins 2018+ MY2013+ Powernet> Connect> Select Hood Open icon>
Select Procedure to Start> Set Max Vehicle Speed> Program Customer Features>
Enter Speed> KPH
Maybe my story is why it's no longer in EZ Lynk
I just tried this on my 2020 and now have to go to the dealer to get my PCM reflashed back to OEM settings.
It was my own fault because I entered the new maximum speed in MPH, it has to be in KPH. My entry was accepted but Alpha (or the PCM, not sure) converted my MPH entry to the equivalent KPH, so now my truck's maximum speed is 69MPH. And tried as hard as I could, I was locked out from correcting it. What I have since learned from Google is you can only change the OEM maximum speed setting one time. Only a dealer can make the next change. So, do this with some caution.
I did the same with Maximum Cruise Control (MPH instead of KPH). Now my Cruise will only set up to 53 MPH. And like Maximum Speed, I cannot correct it.
Those two entries produced two permanent codes, U0415 and U1412.
Sorry for the lengthy reply but I don't want you to go through what I'm going through. I'll know next week what this error is going to cost me. I have an extended warranty but this one was caused by me.
