NEWLY UPDATED RANGE TECHNOLOGY AFM DFM DISABLER FINAL THOUGHTS: Should You Buy It?

After driving around with the newly updated Range Technology AFM/DFM Disabler plugged in for a week, I reveal my final thoughts on if it works on the new 5.3L V8 in the 2019-2020 Chevrolet Silverado's. We discuss the problems I found with the unit and if you should consider buying it or not.

I'm glad I discovered Range Technology. I have a muffler delete on my 2013 Avalanche Black Diamond and even though I never hear a drone, I can hear and even feel when it goes from V8 to V4. I use cruise control a lot and going on a straight, flat road it constantly shifts modes. I can't wait to get my Range in.

[@KevinsAutoChannel]

You’ll really enjoy it and I believe it will make our engines have a longer life as well

[@oloks3804]

Same lil

[@reyanddannyinalgebra2535]

Thanks for the video, I had already ordered mine because I had the muffler being swapped out it will actually be here today. But as soon as I left the muffler shop I could notice the droning, at some points the exhaust would just cut out completely when coasting at a slow speed. Even my uncle who was at the front door of his house asked if they truck was misfiring, I explained to him about the different combinations of cylinders it could run in. Then explained about the range. Was still kinda skeptical about it with the newer trucks but your video sure is reassuring. Thanks again! V8 all the way. #Subscribed

Marvelous Kevin. Both your May 10, 2020 video on the Range disabler and this one. Have become a KAC subscriber and watch all of your videos. Also, the updated Range device for my 2020 Silverado 1500 LT arrived this evening. Have inserted it into OBD and cannot wait to take a long road trip tomorrow through the mountains where we live in northern New Mexico. Again, your channel is great. No need ever to apologize about rants and opinions from you. It is those rants and opinions for which we KAC followers subscribe to your channel. Really enjoy the comments folks make on your channel. I think a good way to judge the value of a You Tube channel is by the quality of the comments. Your commentors are thoughtful and have class. Very impressive. Thanks for your good work. Best to you.

I hopped on to see your Range Tech review. She sounds good. Today I will be testing it in a 6.2L 2011 Yukon Denali XL. All ready changed all wires n plugs. Went from 12.8 mpg to 15.9 mpg. Now We'll see what this moster can really do. I will try to report back soon.

Kevin thanks for the info my 2020 truck is at the dealer now with only 12K miles the situation with the lifter collapsing at the gm dealers is out of control thousands of customers with the same problem with very low miles.GM drop cylinders cutting the oil to the lifters causing big problems on the lifters . Did you hear about this situation happening now with the new DFM system ?? Thanks

15.9 mpg Average with and without Range Tech unit. As a mechanic, I prefer the entire engine to be the same temp, especially an aluminum block w steel plug threads in it and other bi-metal bolts, gaskets, and components. A big factor in engine reliability over time.

Long story short it worked with exact same MPG avg. More fun 😎 Further details n comments below.

Just put one on my 22 Silverado and don't stop it from shutting down to 4 cylinders

[@vdg_loc3266]

Great video . For the actual Range device i give it a 5/10. Reason for my opinion is that my engine bay started smelling kinda funky almost plastic like . Took the device off and the smell went away . I still felt it wanted to drop cylinders during cruising speeds under 50 . I could actually see my rpms going up and down a little. I sold it to a friend with a 2017 Silverado with afm . He’s had no issues with it . I just feel the Dfm is a lil more complex and range couldn’t get it a 100 percent right.

I am getting a flowmaster super 40 series muffler installed in the morning and removing the resonator as well. I am thinking about getting this. I know it says it will not be detected or mess with your warranty. Have you had to take your truck to get any work on it and removed this with them unable to tell that it was installed??

[@KevinsAutoChannel]

I left it in the truck for an oil change and they didn’t say anything. Plus they fixed some recalls too.

[@theboss9006]

When the Range is connected ... and you press the gas ... does your Range light change? and when you brake it returns to normal? I bought one and turned on the last light and when I accelerated it turns on the full bar, I brake and the corner light remained, I accelerated and turned on all the light of the range again

[@militaryminedid2011]

Not sure if you've mentioned it in one of your two review videos, but in my experience after installing this week, the new Range DFM disabler also disables the auto Stop/Start on my '19 Silverado which is awesome. Only twice have I noticed something a bit annoying while using the disabler. It's something I can't replicate but has happened under similar circumstances. When coming to a stop at a red light from a higher rate of speed, I've felt as though the engine was very noticeably helping me to stop, like downshifting in a manual trans where the engine is doing a lot of the work to get you to slow down. I've never felt that sensation in the +10,000 miles prior to installing the disabler. Nothing dangerous or unsafe but just a weird event those two times this week.

[@KevinsAutoChannel]

I haven’t noticed the disabling of the auto start/stop because I have formed the habit of cutting it off as soon as I start the truck. I have noticed though in the past that if you are cruising at a faster rate of speed and all of a sudden start stopping hard that the trans will downshift aggressively allowing the engine to brake as well. It may be a built in “safety feature.”

[@militaryminedid2011]

@@KevinsAutoChannel So I'm not the only one with that experience...good to know. Not a big deal to me however. Enjoy!!!

[@NextUpTunes]

Yes that also happens to me. In my own words I say it “ Boggles the fk” out while Slowing down from a high speed. Mostly happens when the knob is turned to sport mode tho.

[@SycaShow]

It goes from gear 3 to 1.. because of your speed that’s what u feel

[@j.d.mullis9446]

Hey Kevin. Just subscribed. Your truck sounds marvelous. I have the older Range afm on my 07 Suburban. Have had no issues intwo years. Do you ever unhook it ? Should you let engine run w\o it every now and again. I live in NC a little over 100 miles crom you. Be good!

[@KevinsAutoChannel]

Hey JD! Thank you for the support! I have put 1000’s of miles on my new gen Range without any issues or unhooking it so far. I only had it not work for a few seconds one time in all that driving.

Will it work on a 2017 silverado z71 ? I cant stand the initial slow when I start to drive it seems like it's stalling and rpms don't go

Yes it will work on your 2017

[@roysadler4384]

The AFM/DFM Disabler does not work with the GMC Sierra 1500 6.2L 10 speed transmission at this time. Per Range Technology they have a few kinks to work out before they can support this model truck.

[@KeithHendrickson1981]

To my understanding the 6.2L V8 doesn't have fuel management system so you don't need it. The 5.3 and below have it.

[@danielbarrios7420]

Great video man!! What muffler do you have?

It is from a little shop in town called Inman Muffler Shop and it is their custom muffler called IMS Bullet.

So far so good. No major issues to report. Rarely it will not engage but will reset when you cut the truck off and start it again. This has only happened a few times in over a year.

[@KevinsAutoChannel]

I have had my auto start stop engage a couple of times recently and you will feel those surges sometimes. The range and the ECU are fighting with each other for control. The range seems to constantly override the engines computer.
