    • SHORT LIFESPAN & SUCKS BATTERY
Bought it 8 months ago. Worked great but I kept having battery problems. Now the unit does not even work and the listing now states to unplug when not in use. I have had my battery dead dead dead multiple times and have been carrying a booster and jumper cables around JIC. Didn't realize it was the fuel management until I went and read the reviews again and others have had same issues. Bottom line is you can't leave it inserted so what's the point. It will keep draining your battery.. It's $39 now and 8 months ago it was $85????????? ... show more

    • This Here DooHickey Seems To Actually Work..
Having read all the horror stories about collapsed lifters and premature engine rebuilds caused by the Chevy AFM system, I opted to get a bypass widget. Installed it after disconnecting the negative battery cable then fired up the engine (2018 Chevy Silverado 1500 w/ 5.3l with 24k miles). Device worked as advertised and I never had a V4 drop off on a 450 mile round trip pulling a small enclosed cargo trailer carrying about a ton of weight. Mileage dropped from 22 mpg to 13 mpg on highway but it was all because of the poor aerodynamics of the brick shaped trailer. Also had several bizarre prompts on dash--Roll Driver Window All The Way Down Then All The Way Back Up, Open Then Close Driver Side Door...odd. Did enjoy the quicker response when pulling away from stop signs and red lights and ridding the truck of the unnerving floating feeling when going from 8cyl to 4cyl. More precise shifting from the tranny too. ... show more

    • 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. ... show more

    • 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. ... show more
