Works just like it says it should.
Installed in my 2018 chevy Z71 Texas Edition. Works great. Never kicked down in V4. Improved throttle response. Turning 1500 rpm at 65 mph with 22 mpg. Now all I need to do is the transmission bypass and program so the torque converter doesn’t engage until after 2nd gear.

So far so good!
I own a 2007 Chevy Avalanche with the Active Fuel Management system. Every time I would slow down I would get this shudder or vibration throughout my whole vehicle. I had no clue of what could be causing this but did some research. I lubed my calipers, checked and lubed my drive shaft. I changed my spark plug wires, throttle body and was to the point of changing the wheel hubs and the torque converter. After reading some online threads I found the information about disabling the AFM by using an OBD II plug in. I figured what could it hurt. So I ordered this little device, disconnect my negative on my battery, installed the disabler, reconnected the battery and an immediate difference was noticed. V8 mode is now constant and no more vibration/shudder when slowing down. This saved a lot of money I would have spent trying to figure out this issue. Because of V8 mode your vehicle will burn more fuel but at the same time lengthen the life of your engine. I haven’t noticed a significant battery drain but it’s possible it your vehicle is not driven for long periods of time. This device doesn’t delete AFM, it just disables it.

Do not recomment
Bought a few months back and it worked well, on my way home today started the truck up and heard a chime- wasnât worried started to drive home(hour long) and my whole dash lit up like a tree, gauges stopped working or they were just all over the place, pulled over n didnât see any issues, made it 1 mile and it all started again, trans wouldnt shift, gauges, buckingâthe whole 9. Pulled over gained and u plugged this item. Drove home almost no issues. Trans now bucks some times. No lights on and ran codes- found multiple. Kept driving and codes gone but still a slight buck in the trans . DO NOT BUY!! But a reputable company . Attached is a video and a screen shot off my obd2 scanner2010 Yukon xl 6.2l

Great value! Works as-advertised.
This is easy to use, seems to work as-advertised, and the price-point is better than I’ve seen anywhere else. Great value!I haven’t been able to do a highway mileage test yet but on my commute to work I get the same mileage as before, but have the benefit of all 8 cylinders all of the time.

Stopped Oil Consumption
Waited for 2 oil change cycles on my 2013 Sierra 5.3 before reviewing. I change my own oil and filter. I was getting “low oil pressure” because of Low Oil Level with anywhere between 20 to 35% left on the oil life monitor. I would have to add 1-3 quarts to get level back up, and make it until oil change. Also would notice only 2 to 3 quarts left in oil pan upon draining (not counting filter). Reading fourms online my symptoms led to my diagnosis that I had an “over active” Active Fuel Managment lifter creating too much oil spray then burning through the PVC system. Since this device disables the AFM system, as well as reading others online, I decided to try this device.After 2 oil change cycles, I have not received the “Low Oil Pressure” message, AND noticed almost a full 5 quarts drain from oil pan (not counting filter) so almost the full 6 qts added.I am also hopeful this will lessen the chances of having damaged lifters/cam, which is a a common issue with these engines.I also DID NOT notice any difference in fuel economy.I also researched and this device DOES allow overdrive/converter lock up (which is a hack by leaving truck in M5 gear range) I purchased this for my particular issue, which MAY NOT be your issue. Many variables can create excessive oil usage/burning. I had 25 years of GM dealership experience before retiring 8 years ago into the high voltage electrical field. I also use ONLY Dexos approved oil as well as Delco filters. I also change oil with between 10-0% on oil life monitor system depending on when I can get it done.Thats my review. I will update if I notice any huge issues, but for me, for now this device far exceeded my personal expectations.

Works great
I was a little skeptical when I bought it. I ran my GMC pickup truck for a week without it and kept track of the the mpg. Then put this in and ran it for a week. With it in and running all 8 cylinders it’s literally 1% difference in mpg. And my truck runs smoother with it in

Good for a while
Purchased in late 2021 and worked ok, as of 2024 noticed it was going back into V4 afm mode and only one light on the afm device was on. Tried unplugging and plugging back in, same thing. Guess after 3 years they go bad but they use to cost 115 bucks, now 40.
