OBDAFM Active Fuel Management Disabler Device, AFM/DFM Disabler Compatible with Most GM V6 & V8 Motors

Bought for my 2017 Corvette. Ever since new the cylinder deactivation has driven me crazy. Seemed to constantly engage/disengage and had detonation when it did engage. At first thought I had bad gasoline until I started researching. (So dumb for such a feature to be in a performance vehicle).This device has made a world of difference in drivability. Had the opportunity to drive the car 60 miles or so yesterday 05/12/24 and very pleased with the improvement. Now the car is smooth as silk on the road and no more detonation.Highly recommended. Wish I had gotten one sooner.Only thing I don't like is having to unplug when not in use as it stays powered. No big deal though.

Works perfect

Day 1 with this device and so far it has worked flawlessly. Just plugged it in, the left light flashed a few times, then the right most light went steady state, no more annoying afm turning on and off when putting through my neighborhood, or at a steady cruise. In my case it made a huge difference. AFM kicking on and off jarred the car, added obnoxious drone, and added lag when stabbing the throttle a bit due to AFM needing a moment to turn off and then the transmission to kick down. Just didn't feel right at all when cruising around and throttle input could be varied often. This car has a custom tune for a morguson supercharger, headers, high flow cats, full exhaust and this device so far works like it should and doesn't appear to have messed with anything else in the tune. (Bought the car this way, previous owner left AFM enabled.)I will still do a cam swap to get rid of the AFM lifters, but this made it more enjoyable until I can make that happen at a fraction of the cost of other recommended options.Also the unit comes in packaging that I feel is easily returnable, and resellable, if it didn't work for your application. The unit I received could have been bought and returned multiple times but in this case I see it as a plus.In my application the lights face straight down so don't bother me at night, and I have seen posts about how other brand devices would hit you in the shin requiring a cable adapter to relocate it, I am 6'1" and 200#'s, this device doesn't get in my way at all.Hopefully this holds up to time, I will update if I run into any problems.

Simply plug this in, and it disabled, the four-cylinder AFM We’ll see how long it lasts but for right now seems to work fine perfect, no issues

Love how it sounds, drives and runs now!! Have read warnings if not driving the vehicle frequently to unplug due to wearing down battery but have had no issues! Love this, would definitely buy for another vehicle or recommend.
