I have a 2010 yukon xl denali, plugged it in, it turned on and works great. Super affordable and does what you need it too. I'm in V8 mode the whole time and it increased my fuel milage.

Works really good . I just bought this 2018 esv and noticed that at idle it has a slight wobble. I am already aware of the lifter issues with these years. So i got this day 2 . Big difference in power and response . Haven’t monitored the mph just yet but ill come back and let yall know . Also yes i do have the 10 speed transmission and it worked for me

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.

A lot cheaper then the bigger named ones, and so far it works great.

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.

Worked very well for roughly 6 weeks then it no longer lit up or disabled my active fuel management one day….paid almost $90 for absolute garbage. I plugged it in before each use and unplugged it each time I turned my truck off, following the manufactures directions perfectly. I can’t return it to Amazon because it’s been over 30 days & I can’t get a hold of the seller. Don’t buy this brand AFM delete from anyone. Period. Very disappointed, I will not buy a replacement from here (which is now half the price I paid a couple months ago. Complete rip-off, definitely not made to last much beyond the bs warranty. On the verge of being a scam, do yourself a favor & stay away

I have heard in the past that DFM/AFM systems on my type truck will have damaging effects. I conformed this with my Auto Tech. Since I have installed it, easy as ever. I have seen V8 power all the time and my MPG average has gone up buy. 2.5GPM. Highly recommend.

I am a professional mechanic. Put this in my wife’s Cadillac Escalade. It works as intended. Why pay four times this much when this one works great.

First thing is the price, I just couldn't bring myself to pay more than $300 for the Range unit. Just wasn't worth it to me. However, at this price point of $62, it is a no brainer.Works great, truck feels smoother, overall better than it did with AFM turned on.I recommend that you also purchase the cable with an on/off switch to cut the power when the engine isn't running. This will make sure the unit is not drawing power from your battery.Cable:https://www.amazon.ca/dp/B0B417611M?ref=ppx_yo2ov_dt_b_fed_asin_titleI routed the cable from the OBD port towards the right, along the underside of the dash to the center and zip tied the cable / unit there so I can access the on/off switch more readily with my right hand.I also purchased the extended warranty, I typically never buy a warranty but in this case, for just over $5, I protect myself for 3 years from having the unit fail after one year, which some buyer had noted in the comments.All in all, at this price with the warranty, it is a steal compared the the overpriced Range unit.

I I purchased this item in Sept 2024. I worked as intended for a period of time but suddenly and for no apparent reason it stopped working. Additionally, when it failed I noticed my tachometer and speedometer needles jumping up and down which caused me concern. I immediately removed it from my OBD port and stopped using it. Now I can't seem to find a way to communicate with the seller to discuss the issue
