A myriad of electrical gremlins with the new “Atlantis” CAN electrical architecture. Wheel speed sensors that are flawed. A DEF level and pump unit that is flawed. Glow plugs that are shorting out. The CP-8 HPFP making unknown noises the source of which is as yet unidentified. I could go...

I’m not a fan of that recommendation either, however, in theory it shouldn’t be a huge concern because the filters should be installed and fully seated before any fuel is added. Since the system filters from the outside of the filter to the inside, the fuel passing through and to the HPFP is...

CP-8 is extremely stout compared to its CP-4 predecessor. Shouldn’t be any issue with those long term. The way they beefed it up is pretty substantial. Commercial B6.7’s are still flat tappet and will be that way until replaced by the 7.2L DOHC engine next year. You can tank Stellantis for...

Current factory filters are rated for 15,000 mile intervals and have a built in system that will alert the driver to change them earlier if the system detects a drop in fuel delivery. Fuel filters work better as they gain hours of operation and collect debris. No reason to change them earlier...

Wouldn’t recommend a FASS on these trucks unless you’re so heavily modified the factory lift pump can’t handle the fuel demand. (2025+ lift pumps move more fuel than previous 2024 and older trucks) Water-absorbing fuel filters are a no-go on any vehicle, and their continued reference to micron...

The level of disconnect between the dealerships and Ram / Cummins engineering is astounding. The left hand literally has no idea what the right hand is doing. Simply astonishing. There’s no software update that will fix a mechanical / physical flaw with the filter housing. New parts are in the...

You missed a regen cycle in there somewhere, or you had some sort of software flash in between. It’s physically not possible for the truck to go that long without a commanded regeneration cycle. 24 engine hours (give or take a few) is the maximum amount. There’s a timer that counts up to the max...

I have some questions… Is it a 2500 or 3500 (SRW or DRW?) SO engine or HO engine? Current odometer reading? Current idle and drive hours? What is the Date of Manufacture for your truck? Have you ever sent your used engine oil out for analysis? (If yes, what did fuel dilution look like?)...

Depends on the model year, as well as what state it was sold and registered in. Some carry a 7yr / 70k mile warranty under the “California” emissions warranty. My 2022 sold and registered in PA carried the 7/70 emissions warranty because PA follows CARB guidelines.

I have two nearly identical trucks in the driveway right now. One has anti-spin, the other doesn’t. Both are 4wd. We’ve had 10+ inches of snow here and zero or sub zero temperatures. The one with anti-spin has been demonstrating all week why anti-spin is a worthwhile option. Won’t own a truck...

Cummins is having some issues with the glow plugs causing shorts / short-cycling. When you attempt to start, are you holding your foot on the brake pedal? Have you tried keeping your foot off the pedal? Any check engine lights or trouble codes ?

Correct and confirmed ✅ Cummins is handling the emissions on 2025+, not Ram. They wanted to increase system reliability and performance over previous years. That’s why the 7th injector was applied to this current design. They’re using two DOC’s to keep EGT’s up, which in turn improves overall...

If you’re using the correct viscosity (5w-40) you’re getting oil flow pretty quickly. That’s the whole point of the newer changes to recommended viscosity based on environmental temperature. The block heater should be used as much as possible / whenever possible. Straight cold starting these...

Lots to take in here: Some initial points: You’ll need a pretty high level scan tool and a bypass to get able to perform a parked regeneration. Since it’s a 2025, you may be forced to go through the dealership as it’s an all new CAN-FD architecture that a lot of aftermarket devices can’t fully...

Also allows for automatic updates to the software everytime you connect the app to the device. If there’s a flash update available, it’ll do that while you drive.
