2020 1500 with Eco-diesel....What's the word on her?

So I'm coming up on 11,000 miles now. Still not driving much due to working from home during COVID.

The timing cover leak at roughly 5,000 miles is still the only issue my truck has had that required repair.

I did go in for a voluntary PCM flash a couple of weeks ago in hopes that it would fix the HORRIBLE drivability, throttle response, and lag in this powertrain. It's been a widespread issue with the Gen 3s. I suspect that the tail pipe butterfly valve that they're using to "cork up" the exhaust and create backpressure for the low-side EGR system is partially to blame. Drive by wire throttle and a turbo charger complicate it even further. But, I drove a 2021 Jeep pickup with this powertrain and it was nice....very little lag and good engine tuning. So I was hoping that a flash on my 2020 would at least make it drive better. It seems to have helped a little. Not a lot, but a little.

Still seeing 21ish MPGs average. I just replaced the air filter, oil filter, engine oil, and fuel filter myself in the driveway last week. Did it all with proper spec materials for $150.

The truck HATES my new trailer. I traded my 7x14 enclosed for a 8.5x24 enclosed. With an EMPTY trailer I saw 8.5 MPG on a 130 mile trip. Ouch. I was getting 14 with the old trailer.

I saw that Cummins went back to the old CP3 injection pump. The CP4 is trash, and unfortunately that is what we get with this EcoDiesel. I'm using Hot Shots EDT with each fill up, and I keep a file folder in the truck with all fuel receipts and service records. Praying I don't get bitten...

Mule, thanks for the update. I’m not surprised you cut your fuel economy substantially, you doubled the size of the trailer! Maybe FCA will come out with a new flash if enough folks complain about the eco’s poor performance. FYI, Green Diesel is back in business and will have tunes by summer for the latest generation of the ED.

You might consider getting a Pedal Commander, made a night and day difference with turbo lag on my '18. You can change settings depending upon your mood. It woke my truck up. I use the ECO setting and leave it, haven't noticed any difference in mileage. It's also Bluetooth

Any 2019+ eco diesel owners want to chime in on their experiences so far?

Just picked up my 2021 ecodiesel 2.11.2021. So far I love it and have had no issues. Wife even loves it!

Wife and I bought a 2017 EcoDiesel, Black Friday of ‘17. Got a great deal and loved the truck But, it started having problems this year and I made the decision and stepped up to a ‘21 2500 Cummins. I had previously owned a 12 valve Ram and should never have sold it. All this hi-tech electronics sure changes the notion, in my mind, of buying an heirloom on wheels, like I thought in my 1995 purchase.
Regardless, I will miss the fuel mileage advantage, of the little 1500 but, not the fret or worry, of whether it will stay together. I hope that this latest generation of V-6’s does good for their owners!
