Preventing Lifter Failire

[Stormin08]

correct, turn off that selection...they system will then give you the option to download or decline.

otherwise, it can happen in the back ground without knowing,

i had 500 miles on my truck, started and moved 20 ft during a wash one day...hopped in to move again...and it BRICKED itself. Had no idea it was doing an update...that update was corrupted by my trying to start and smoked all comms within the truck.

7 days later, GM flew in a specialist and every module was on a bench being replaced and flashed to the VIN.

thank you

I know with me, I went with having my ECM and TCM unlocked so I could do actual tuning in addition to disabling the DFM and Auto Stop/Start. So, that is my rationale for spending the money.

That makes sense, your goal wasn’t to just shut the DFM down.

thank you for your know how. I would like some help on turning the OTA off .
I went to my settings and found the notification on updates . it had a green check mark on , is that the one you would turn off so they can't send an OTA without me being notified ? last time they sent me a notice that it was available when ever I needed to install and I did the install now box.
since I'm planning on installing a Range RA007 do I need to remove the green check box to off or just leave it alone and not ever have them install it ,or remove range and install the OTA update

sorry for so many questions but kinda confused.

Another thing I do recommend is whenever you do, if ever, decide to accept any OTA updates or go to a dealership, I would be sure to disconnect the module. When I was still using the Range module, I made the mistake of not removing it before downloading an OTA update. That update corrupted or rewrote something in the ECM because after the update, the Range DFM Disabler no longer worked.

Hey All,
I am gathering info and opinions on the best and most cost effective way to prevent lifter failure in my 2020 Chevy Custom Trailboss. I’m currently at 68,000 miles and have had no issues at all. However, I keep hearing about folks who have these engine lifter failures which cause all sorts of major problems. What are your thoughts on purchasing the Range AFM/DFM OBD II plug in to help prevent the issue?? I certainly don’t want to do a manual AFM/DFM Delete for all that money. I will be certain to change oil on time and with high quality oil. But, will the plug-in be the best bet to prevent lifter failure? Thanks

Carbyte works the best!

With Carbyte, it’s my understanding that you need to first get to 40 mph for it to activate and shut off the DFM and auto stop start for that driving/motor session. But Carbyte is way, way easier/more convenient to connect it and disconnect it via the OBD port versus the driver side wheel well approach of the Range in line with the ECM.

Both should be removed before any OTA update or before visiting the dealership.

Question: With carbide, once you reach 40 mph, “how long” must you be above that speed before Carbyte does its thing?

(Lol I keep thinking of Marty McFly racing across that mall parking lot until he reached 88 mph to activate the flux capacitor)

I have never had a problem with Carbyte and always works immediately after plugging it into the OBD. I also have one installed on my 2025 Blazer and works flawlessly.

How do you validate that it’s “working”? To say it works immediately runs counter too just about everything I’ve seen about the Carbyte and its requirement to achieve 40 mph before it activates.

The vehicle will not shut off when installed even when not going over 40 MPH and I don't think DFM works before 40 anyway and how many times do you drive under 40 all day.

 

[jfboss]

Got it. So you’re saying the auto start/stop function shuts off immediately, but for DFM itself to be disabled you need to exceed 40mph. Ok.

Just an FYI, this is not only a GM issue...Harley has this similar issue going on.

i have had numerous people with the Current M8 motors have failures with lifters (some are even made by Johnson... same as LS7 rollers)
the metallurgy or the heat treatment one, is not sufficient

Feuling are my go to, but, ya never know.

I don't think DFM works before 40 anyway and how many times do you drive under 40 all day.

DFM works down to 0 RPM when decelerating.

Well even though the Range will arrive in a couple days there’s still time for me to change my mind because Carvana just advised a transpo/logistic delay on my order of 11 days. Hope THAT reschedule doesn’t slip. This is my first Carvana. 2023 LT TB 5.3 and can’t wait.

There is absolutely no reason to change your mind, you made the right choice. The talk of the "hassle" to remove the Range Module is wildly overrated. This may be hubris, but I bet I could get mine out while holding my breath.
