Frequently Asked Questions
How does that Work?
The CylinderGuard module plugs into your OBD2 port and sends a passive signal that prevents the ECU from engaging cylinder deactivation mode. It doesnot reprogram or write to your ECU— it simply interrupts the AFM/DFM trigger so all cylinders stay active every time you drive.
Which vehicles is it compatible with?
CylinderGuard is compatible withV6 and V8 GM-powered vehiclesincluding Chevrolet Silverado, GMC Sierra, GMC Yukon, Cadillac Escalade, and more. Supported engine sizes:4.3L, 5.3L, 6.0L, and 6.2L across model years 2007–2022.
How to install? Do I did a Mechanic?
Not at all. Find your OBD2 port (under the dash, driver's side), plug in the module, and start your vehicle. The entire process takes under 60 seconds with zero tools. To remove it, just unplug it, no trace left behind, vehicle stays completely stock.
