Qzucar

Qzucar is an aftermarket gadget designed to disable the Active Fuel Management system in certain General Motors (GM) vehicles. AFM, also known as Displacement on Demand (DoD) or cylinder deactivation, is a fuel-saving technology that allows a V8 engine to operate on only four cylinders under light load conditions.

While this can improve fuel economy, some drivers experience issues such as rough engine performance, increased oil consumption, and unwanted noise when the system activates and deactivates.

How Qzucar AFM Disable Device works

The Qzucar AFM Disable Device seamlessly integrates with your vehicle’s On-Board Diagnostics (OBD-II) port, functioning as an intelligent override to the Active Fuel Management (AFM) system. Once connected, it blocks the activation of AFM, ensuring that the engine runs on all cylinders continuously, without the intermittent deactivation that typically occurs. This results in consistent power delivery, improved throttle response, and an overall smoother driving experience. The device is designed for effortless installation, requiring no modifications to your vehicle’s engine management system. It provides an efficient, non-invasive solution to enhance engine performance without the complexity of professional tuning.

What people say about qzucar

Customers reviews

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.

Installed after repairs to a ’13 Yukon 6.2 with collapsed lifter. Is working great,fuel mileage is actually increased. Simply plug it in .

Works as advertised,didn’t change my gas mileage very satisfied

This made my 2018 Silverado 5.3 V8 actually a V8! Buy it and don’t worry or wait. If you have looked at them just get it. Its awesome when you press that pedal and there’s no lag from 4cyl to v8 and no awkward shifting back and fourth. That alone is worth the money if there was no mpg saving but there is. I get 1-4 mpg better depending how I drive and even saw 6 mpg better on one trip I made.
