AFM/DFM Disabler Active Fuel Management AFM Disable Device Compatible with V6 & V8 GM Motors

Works as avertised. My Colorado doesn't go from V6 to V4 anymore. No more hesitation while my truck switches back to V6 when I floor it. My Colorado has been using around a quart of oil per 2k miles since new. When I plugged this in and stopped the cylinder deactivation, it stopped using oil.

This plug keeps my 2010 Silverado in V8 mode. Certain GMs have the feature that was supposed to save gas by turning 4 cylinders off. There are apparently a number of issues that pop up as the engine ages, such as lifter issues and oil consumption. Also, there was a bump I thought was a transmission or rear end problem in city traffic but seems to have been the truck switching from V4 to V8 abruptly. Works as advertised and has bright LEDs to let you know it’s on. There are way more expensive ones, but for around $85, this is the most economical choice to alleviate the issues that arise in older vehicles with a feature that might have been a good idea, initially, but apparently doesn’t age well.

Highly recommend and easy set up just plug it in and you’re good to go

Works great on 2011 5.3 tahoe. Just plug it in and crank it up.Fantastic product. 8 cylinders all the time. Perfect.

I bought this to address a stabilitrack error I was getting that seemed like it might be related to the AFM issue on 2007 GMC Sierra 1500s. When that error happens, the engine runs really rough and it shifts hard. When I first started using it, it felt like the engine was still riding just as rough, but I wouldn't see the check engine light or error pop up, and the shifts felt normal. After a while it felt like all the cylinders were banging again, and the truck was running great. I drove it a handful of times, and it felt like it might be a permanent solution. But two rides later, I felt the engine running rough again. Still no stabilitrak error or hard shifts, but it definitely felt like i was down a cylinder. Then I got a new battery and put high octane gas in and the truck has run well in the week or so since. So I think it's working? I'll need to pull it and see what happens at some point. Even if it does work, I wish I'd have put the money for this towards a tuner that could shut down AFM for good and also give me performance options.

We had to rebuilt part of the motor in our suburban. Told we would probably have to completely replace. Husband did research. Found out about this transmitter. It’s did its job. We’ve actually showed it to our friends and even orders it for a few. Our motor is 2 yrs later and going strong

This saved us after having to change out stuck lifters and now the truck runs in V8 mode at all times while plugged in. I don’t mind losing gas if it fixes the common problem GM models have with lifters. Questions if all 4 lights aren’t on while being used is the device ineffective?

Enable your vehicle to operate on all eight cylinders at all times. Stop the computer from changing from eight cylinders to four. It could save your engine from future problems. Make sure you read the description before you purchase.
