This device works. My mileage actually improved a bit, someone at GM should explain that one to me.
Color: Grey/black
This unit really works. My new 2018 Silverado 1500 ("e" model) was running well before I plugged it in the OBDII socket, but I wanted the option of disabling this V8-V4 mode because of what had happened to my friend's 2011 Sierra 1500 (excessive oil consumption between scheduled oil changes due to worn rings on an otherwise meticulously maintained truck. This was traced to a lack of proper lubrication in V4 mode, an issue supposedly fixed since in the newer models). I just couln't afford to take any chances at having to go through an engine disassembly so soon in my truck's life. I mean, how long have they been messing with V8s? They should have left these engines alone instead of messing with cylinders 1, 4, 6, and 7. Since I do mostly highway trips, my mileage has actually improved, not by much, but it shouldn't have if you believe the GM hype. You really have to wonder why all this V8-V4 complexity was added to a perfectly good V8 if as, in my case, my mileage improved!!! The ONLY thing I miss at times (easily fixed by shutting down the truck and just unplugging it from the OBDII socket) is some engine compression braking in hills from the V4 mode. It helped me maintain a set cruise speed going down some hills with a light 2000 pound trailer load, and the fact that the engine no longer shuts off at stops or red lights (the "e" model has the Lithium battery pack and induction motor to spool up the engine under these conditions but it won't do any of that while this particular unit is plugged in). Other than that, I have the V8 I expected now, the mileage is fine and hopefully I won't have issues with failing parts in cylinders 1,4,6 and 7. The added complexities of these otherwise old V8's should be a cause for concern. They use a special camshaft ground differently just for cylinders 1,4,6 and 7, they have a higher-volume oil pump, and a pressure relief valve to handle the incessant oil/computer controlled operations of the intake and exhaust valves in these 4 cylinders and this device just stops all this from happening without reprogramming anything. I could be wrong of course, but I think the pressure relief valve should have no issues handling the changes for the life of the engine. The rest is literally put to sleep while this device is plugged in. If you want to take your truck in for maintenance, say while it is still under warranty, just remove it before going into the stealer. They will never know. Hopefully I'll never have to go in for expensive repairs due to failures with cylinders 1,4,6 and 7. Make sure you get this device with the latest firmware as it is now totally stealthy to Onstar's big brother monthly reporting. Range Technology has done its homework. I don't work for them, I'm just a happy customer and would recommend this to anyone just wanting back the V8 truck they thought they bought.

This thing saved my 5.3 Silverado!!!!!
Color: Grey/black
Researched the oil consumption problem on my 2008 Chevy Silverado 5.3 with Active Fuel Management, and found that when truck goes into 4 cylinder mode it begins to use oil to the tune a quart every 1500 miles. Decided to buy Range AFM disable module and it works great! Oil consumption is virtually non existent with 85K miles on the truck I change oil every 5 K miles and surprise the oil is still there. It runs strong in constant V-8 mode which has not effected overall mileage one bit. One thing I noticed that you have to check on information center once in a while to make sure unit is working because after I let the truck sit for a few days with module plugged in I noticed it was not working. I then unplugged the unit and plugged it back in and it worked, this occurred twice in a 6 month period. If vehicle is not to be driven for more than two days I unplug the module and haven't had the problem since. This unit is well worth the money spent to save my engine from damage from the GM blunder of Active Fuel Management, which in my opinion is inexcusable disaster inflicted on what in my opinion is one of the best trucks ever made."Product Update 11-23-16 my truck has 93k on it and today the truck began shifting very hard... I thought maybe transmission was letting go but remembered someone commenting on how the Range module was causing this with their truck. My solution was to disconnect Range module, then connect code reader to scan the system no trouble codes found. Then I cleared system just to be sure and installed Range module again. Everything is fine shifting perfectly I assume there is a firmware update for this problem.

BUY FROM RANGE TECH WEB SITE ONLY....Watch for 3rd party/out of date units!
Color: Grey/black
Does not work on 2015 Silverado nor a 2009 GMC as bought AFTER TURNING TRUCK OFF. HOOOOOOOOOOOOOOOOOWEVER, after finding out the item actually came from a 3rd party (Zennith Performance) and may be OUTDATED (old software version) according to the actual maker, Range Technology...I sent it back to Amazon and said 3rd party. I thought I had purchased it from Range but that was not the case even though Range does sell on Amazon they say. I was unable to find their page and have since purchased one from the actual RANGE web site (also has choice of 3 led color's) and after speaking with them, was told it would be the latest and greatest version and would work with my 2015 Chevy. I will update more when that gets installed. Check Warning on Authorized dealer/sellers on Range Technology web site! ACTUAL PRODUCT USE: after installing the unit "AFTER" trucks were started, I got a blinking light and then a steady light. Unit seems to work very well in solving my AFM vs. 6-speed fight on whose in control problem and truck ran very smooth and was pleased. It worked good in the 2009 GMC also BUT when trucks were turned off, unit would also turn off. Once trucks were restarted, Unit DID NOT restart and that forced a disconnect/re-connect of unit to wake it up with truck running. I will update this review once I have the up to date unit from range Tech... Add't Notes: You also get your out of date unit, older units updated for Free, see Range Technology web site. UPDATE: Got my new unit from Range with Version 8 loaded. Installed it and went down road and truck went from V8 to V4...WTHO? It then went back to V8 and hasn't changed since, stays in V8 with steady blue light. Goes off when truck is off, comes back on when truck started. No faults are showing on dash or anything and truck run awesome and smooooth1 So far so good. A winner I think and ONLY BUY FROM RANGE!!

Color: Grey/black
Shame on GM for putting an 8 speed transmission into a 5.3 Chevy Silverado with AFM! I've owned a 2016 Silverado 1500 with a 5.3 4X4 for about 6 months and I totally hated it. That was until I found this little gem. I was going to wait to get a programmer, but I didn't want to go to that extreme. I've made a few observations pre and post Range AFM disable. Before the symptoms I had were a lot of throttle lag, the transmission would jerk in and out of gear while in v4 mode and when switching to and from V8/V4 modes. There was a slight shutter on light to moderate acceleration. It was like the truck did not know whether or not to go into the next gear or in or out of v4 mode. I spend most of my time driving on 45 MPH roads and the drive-ability with the Chevy at these speeds was horrible. While the truck was in 8 speed driving around at 45 MPH and in traffic, the engine and drive train was always in a state of lag or being lugged down. There was virtually no throttle response. The only way the truck was drive-able was to nail the throttle to get the RPMs up and change into a lower gear. Can someone please tell me in the infinite wisdom on GM's part how that saves on gas???? Enter the Range AFM disable. Now I can drive around at 45 MPH and if I need to gas it, the truck will easily go into another lower gear and move. Mostly now I can drive around and in traffic and the truck stays in the 8th or 7th gear without any problems at all. There is one anomaly I have noticed, and this I think is the reason for some bad reviews, is that this did throw a check engine light already. What I figured out was, as soon as I let my wife drive the truck, she throws the thing in gear and hits the accelerator before the starter barely finishes turning over the engine. Every time I've gotten into the truck to drive it I've took my time and gave the Range plug enough time to initialize. I am totally sold on this device and it has made thew driveability of this Chevy 300% better with the AFM disabled. Gm should take some notes here and learn from their horrible mistake. This is causing them to loose sales. Consumers should not have to purchase devices to make a truck run better. They should make this a switchable option from the factory!

RANGE V8 FTW!
Color: Grey/black
The Chevrolet Camaro SS automatic (L99 engine) was built with AFM (active Fuel Management) which puts the car into 4 cylinder mode when the car is under light load. While in theory this seems like a good idea and helps GM meet the Federal CAFE standards. In practice, for a high performance car such as this it's horrible! You can hear and feel when the car goes into 4 cylinder mode. There is a slight lag when needing power to pass, or just accelerate a bit to keep up with traffic and a HORRIBLE "Farting" sound as residual fumes are detonated when the car comes out of 4 cylinder mode. Until now, the ONLY way to disable AFM was to have your car tuned that can and will void the 10 year, 100k mile powertrain warranty. I wasn't ready to do that so begrudgingly decided to keep driving a FART car!. Enter the RANGE V8!!! This simple device plugs into your OBD-II port that fools the car into believing current conditions are not right for the car to enter 4 cylinder mode without reprogramming the ECM. At first I was a bit skeptical. But after reading some initial reviews from early adopters I bought one. IT ABSOLUTELY WORKS as advertised! I Plugged it in and took my car for a quick test drive. IMMEDIATELY (before I even got out of my subdivision) recognized that AFM was not engaging. A longer test drive confirmed this. At a later point, I removed the device and AFM began engaging again which proves to me the ECM was not reprogrammed. This is truly the best of both worlds. I can used the RANGE v8 when I want. When I take a long highway trip and am interested in keeping my MPG high, I simply remove the RANGE V8. For my daily driving (when AFM bothers me the most), I keep it plugged in. Simple two minute (if that) install. Unbox, and plug into the easily accessible OBD-II port. Highly recommended to anyone that is bothered by the AFM. I understand this works on ALL GM vehicles with AFM.
