Active Fuel Management disabler for GM vehicle. Chevrolet, GMC, Cadillac 2007 - 2021 Review. Parts Needed Range Technology AFM Disabler - amzn.to/2X5arXD Range Technology Website for more details. www.rangetechnology.com
I've been using this unit for 6 yrs and I've never unplugged it in that time...never had a problem with battery drain even when parked for 1 to 2 weeks at a time.
I have a 2017 GMC and had no lifers issues now I only have 36000 km.. I have purchased the Range chip and have had it plugged in for 2 days and I can definitely feel the difference as far as I’m concerned it’s preforming better!!! Very impressed and it’s only been 2 days 👍🙂
hey guys is you RANGER chip or plug.!! when you turn off truck is the chip turns off.?? l hear people said the chip stay on all time even when truck is off.!! how your works.?? please
Thanks. I got a 2008 sierra 5.3 with high miles and looking at getting one while i get ready to do the whole afm delete process. How is everyones running long term?
They are great for longevity as well. Your transmission and lifters will last a lot longer because the torque converter won't be locking out and the lifters won't be collapsing and expanding causing wear and tear on everything.👍
Hey Chris, great video. I just bought one of these for my 18 G.M.C. 1500. Watched your vid and a couple of others before installing. Just went for a ride after plugging it in and could immediately tell the difference. Throttle response is way better. My truck has a Flowmaster on it so I could always hear when it went from V8 to vacuum cleaner mode. Thanks again for your clarity in the video.
I had one on my 2017 HC 6.2L it worked great. Also the truck sits for months at a time and it never drained the battery, just wanted the public to know. I sold Range and did a Trifecta tune and had AFM deleted. Great video. Cheers
This little plug and play is a God Send I put this on my 13 Suburban with 143k on it now has 174k on it and even without doing anything to the afm lifters it's greatest plenty of power its best thing since sliced bread! If you've got a 5.3 made after 06 You need to get this today you wouldn't be sorry!
GM had the 8 - 6 - 4 cylinder thing on some Cadillacs years ago and it was nothing but problems then. Can't imagine why they tried this again and are STILL using it. It's a trash system that can cost you a TON of money when it fails. EPA needs to get their nose out of everyone's business.
I have been using my Range for several years now and it does do the job for deactivating the AFM system. The only issue I have is that it seems to prevent the emissions drive cycles from being completed as well as preventing certain check engine codes from being turned on. You have to pull it off and run it to see the check engine codes.
I have one of these in my 2020 Acadia, Works Great! I just pop it off when it goes to the dealer. I permanently was able to shut off the Cylinder Deactivation in my 2016 Silverado with the programmer. Truck is so much smoother without it. Neither the Acadia or the Silverado are sitting around trying to pick how many cylinders first, and then a gear, I hate AFM!!!
I've had mine installed for a year now and not an issue! Hopefully this is some preventative maintenance for lifter failure as well as the infamous torque converter issue, and i do 3000-3500 mile oil changes. I plan on this 2017 Silverado to b the last truck i buy! Lol. With a prayer and a lot of hope
Or just the day of will be fine. You just don't want to have anything plugged into the OBD2 Port when taking it in for inspection. Great comment! Thank you!
@@cdarnau i have unplugged mine in the parking lot of the inspection station and it wouldn't pass. I have to put a few drive cycles on it for the computer to clear everything so it will pass
@@dwa3093 I wonder why that would be. It does not change any of the program information in the module itself only sends an input that doesn't allow the system to enter 4 cylinder mode. I am very curious now to see why that is. I am calling my contact at the company to find out why. I will update you when I have more information.
Thanks! I am sure you are going to love it! I have one on all of my farm vehicles and my in-laws vehicles. They really are a life saver! Thank again for watching!
What was your first symptom that you got. I am getting a flashing check engine light and it goes away now I have a light. Did yours run super rough? Mine sounds smooth still but the auto start won’t work
Yes its your lifters going to shit mine just went to shit i didnt no bout this v6 v8 mode shit with gm lol so now im disabling it getting the delete kit from texas speed performance in Georgetown tx only 30 mins away so yeh 188 for the main kit and they got a sell labor day
then i would enter maximum speed :( I can shift it into M4 to disable the AFM but it disables the Overdrive sun gear so i lose like 2 city-7 hwy with out the Sun OVERDRIVE gear.. so the engine runs at about 2,000 RPM at 60mph instead of 1400 rpm with the SUN overdrive gear (this gear is worth 7MPG on the highway)
I have a 2014 with a six speed. Will the truck still go in 6th gear for the best gas mileage with the range plugged in? Just want to be sure it will limit my gearing and keep me in 5th gear. Thanks
Great video and channel, I subscribed. Just got a 1500 2012 with 57k on it. I love this truck and I want it to last. Has the device been reliable after 3 years? Thank you for your time!
Thank you man! I really appreciate it! I have not had an issue at all with mine. I also have them on my wife’s vehicle and both of my farm vehicles. No issue to date.
I ave a 2012 Avalanche from new, and I have been putting mine in manual for city driving. While it works, I am getting tired of doing it, and of course, on the highway, even in manual and you put it in 6th gear, it will still activate AFM. So this will do the exact same thing without doing that manual trick? I dont think I have any lifter issues, etc since I have no engine issues that I know. Would I cause any issues to my truck if I install one now after 10 years of ownership? Truck has 175K on it, and plan on keeping the truck for many years.
I promise you GM does not want to have AFM on their vehicles. This is what they have to do in order to meet government regulations. GM would rather put a non AFM engine in a vehicle and save the money on the programming, expensive lifters and all the components required to operate it properly and still sell the vehicle at the same price. This is what GM and all manufactures have to deal with to meet EPA / Fuel Mileage guidelines. It's really quite sad.
I had an oil leak from the shaft of the vacuum pump, so I was planning on taking it off and plugging the holes in the block. I installed the Range afm disabler , and the stop leaked. I'm still gonna delete the vacuum pump, but I wanted to ask if disabling the afm makes the vacuum pump not be needed any more? Why would the leak stop? I checked the engine oil level, and it's well in the normal range.
Since GM created all these expenses for thousands of people. Perhaps they should send a free disabler to every customer. But that would cut into their hey we wanna screw u profits
This doesn’t keep a lifter from failing. If the VLOM fails, a lifter will fail anyway. I’ve had two failures on a 2016. None on a 2010 and I’ve run the range on both for years.
Does GM have shares in Range Technologies? Sad they can not produce an engine without complications after so many years in business. Make work project!
So which one is it the ra003g or is it the ra003 model im confused the one u got is 198 and the one u added rhe link too is 189 but not the same as the one u show in ur video
Question. My Tahoe has a failed lifter 167k on the motor. Obviously it’s the afm. I keep hearing about the delete. If I change all the lifters myself and then installed the range device would that work? Or do I need to do the delete? Thanks
It tricks the ECM into thinking there's a higher engine load than their really is. It won't affect your gas mileage but it sure as hell makes your throttle response snappier
I bought one to save my lifters but ic alot of people saying this range ruins your transmission so idk what a pain. Why cant thry just make things to last anymore
I have ever heard that. I am not sure how the AFM could cause your trans to fail. Not saying it couldn't. Many things can cause your trans to fail. Heat being the most common thing.
@@cdarnau hey thanks for the reply. Yeah I'm not sure either im no mechanic that's for sure. They all they after plugging it in it makes the truck shift much harder.idk the logic behind it idk how it how works but seems to be the only complaint ic about range. Is the hard shifts and ruin the tranny. Other than that I haven't seen any other complaints researching this item They also only complain about the down shifts no issue shifting up
@@RednGold10 No problem. I love learning new stuff and if it causes a problem I have a direct line to the company I can call to give them feedback. I haven't noticed that and I have it on all my vehicles. I am not sure if I am just use to it or what. It's possible that they were having issues with the trans prior to install and this just makes it more noticeable? I have been running mine for the last 3 years and my trans still has not failed. Watch me walk outside and drive today and the trans fall out. Lol
@@cdarnau lol well gives me more confidence to use mine when it comes in the mail. Cause it definitely saves the lifters per everything ive seen. So I guess hopefully I have no issues with downshift!
Lifters can always fail for any reason. This device keeps them from activating and causing an AFM failure which is what the title and information of this video is about. My facts are 100% spot on. Your English and grammar on the other hand… But please, go back and watch the video again. Make sure the information is 100% spot on. Show it to your friends and family. Make sure they agree with you that my facts are incorrect. Whatever Social media you have please show your limited angry audience to see if I am incorrect. When you're at work... show them and have them come on here as well and let me know how incorrect I am. I really need all the feedback I can get to make sure my facts are correct. So please... get some more opinions, come back and let me know. Thanks again for watching!
@@rcan08 Anything can fail. The roller on the lifter can go bad. The spring could break. The oil passage could get debris and block. This keeps the AFM from activating. The reason AFM activation causes failure is because some times they will not reopen or expand because of an internal failure on the AFM system. This keeps the AFM mechanism from operating so the lifters do not collapse and fail which is the most likely failure in an AFM system. If you purchase this could a lifter fail. Absolutely. Will it be AFM related which is a higher percentage of failures than a roller, spring or oil passage failure? Absolutely not. This will keep AFM from causing your lifter to fail.
@@cdarnau thank you for the answer. I have a 2020 Silverado 5.3, I looked on the Range website and they only showed up to ‘19. I’ll keep checking back I guess.
I'm about to tear into a 2010 Silverado i just bought for $1500. Has the collapsed lifters, after I fix it... hopefully. There's a range on fb marketplace but it was used on a corvette... would that still work?
No, but I managed to fix it and it's still working almost a year now, according to this post. I disconnected the brake booster electrical lead as per some other web info.. I think that canceled the afms. I don't notice a lag or here a weird humming sound from the muffler.
@@342boss I'm really not sure. I just plugged it in to a new body vehicle and it didn't allow it to work when I had it. Maybe it was a fluke? Not sure.
I spoke to RANGE and they don't have one for the 2021 models yet. My GMC Sierra at 4800 miles already needed a cylinder, valves, rod etc replacement :/
@@cdarnau I thought that too, but contacted RANGE just to be sure, their CR said nope it won't work in the 2021. They are currently working on one for the 2021 year. Just wanted to let folks know what they told me. Thanks for the video!
I’ve herd this will help on oil usage as well . If you have plug that has be changed more often. Like once year . Is that a lifter problem ? Number 1 plug I just bough AFM disabled want make sure safe to use
@@cdarnau Thank you sir . I bought truck used 2012 model I’ve had 4 years . At least once year have change first plug on left side it will foul out have oil around it lot build up corrosion . I just put AFM disabler in it . It sure runs better . I just ordered new valve cover comes with new pvc valve . Had small oil leak I tracked it down it’s the left valve cover gasket so good time to change all . Thank you very much
Does this have an affect on transmission temps? Because to my understanding it tricks the computer to think it’s under load so it won’t drop the cylinders. On the HWY it’s good but in the streets it shoots my transmission temps pretty high
@@cdarnau so I just got it back and it’s been great. I don’t know what the temps would be without a cooler since I installed a mishimoto 13 row cooler. But nowhere trans temp sit about 125° on a 70° day.
I got one for my 2020 Chevy Silverado so I could put an exhaust on it now that I put on the exhaust I can hear it still shifting into v4 or what ever it’s doing . It starts sounding like a helicopter inside at slow speeds
No mine is the 8 speed and I had this problem with the range disabler so I called the company and they said they’ll send me a new one and the new one is doing the same thing so idk I just put my truck in L7 now and it stays in v8
Going to try it out but worried about the antifreeze smell I have when exiting my 2019 Silverado no leaks just strong smell .Had same thing happen on my 2019 ram antifreeze smell engine was toasted on it .
Someone else did a vid on the same product and he said to have it turned off and wait to turn it on until it stops blinking and the light stays solid or it will cause the check engine light to trip. I'm wondering if it voids the warranty after installing.
@@undertow4629 I don't have any problems with the ones I use and I have them in 3 vehicles. Have not had a check engine light yet. BUT, I leave them plugged in all the time.
Why don’t people complaint the GM to start making this damn motor fuel management is the shit or at least GM should have a switch in the vehicle that allows the owner to decide if he wants it or not if I could afford an Escalade I don’t care about gas
If the cylinder is skipping and you remove the valve cover with the engine running. (be careful not to put your hands near any moving components) the cylinder that has a collapsed lifter, the rocker arm will not be moving.
@@cdarnau Well when doesn’t work and stuck, even one cylinder, that cylinder doesn’t fire thus feeling like a miss. Maybe you call it a skip. But if it’s doing that and the ignition system is in order, one to four cylinders will not be firing…
You will have misfire. If you've never experienced a misfire, it basically feels like ur engine is choking, no power, a lot of vibrations and CEL turns on. Believe me, you will know. I had a collapsed lifter, removed head and replaced. 2 weeks later, another lifter collapsed, did the same job all over again but bought the range afm disabler this time. Have never had an issue again. Definitely recommend.
The engine on my 15 silverado blew up at 75k...I went n bought an 18 silverado n traded it in. If I knew about all these lifter issues back in 2015, I'd be driving a different vehicle. No more Gm vehicles for me.
