Range Active Fuel Management Disable Device Reviews


AFM disabled without reprogramming the PCM

Reviewed By Francis C (Allen, TX) Reviewed for a 2013 Chevy Suburban —2/27/2015 3:01 PM

The Range AFM disable device arrived very nicely packaged. Installation is simply plugging the device into your ODB II port. The off-idle stumble completely went away and the instant MPG display confirms that the Suburban is now running on all 8 cylinders, all the time. Gas mileage did not change at all in the past week. The only oddity is the bright blue LED that shines into the floor. It is not noticeable at all during the day, and I started to ignore it after a couple of days.

Suburban runs like it should.

Reviewed By Robert W A (FREDERICK, MD) Reviewed for a 2011 Chevy Suburban —1/12/2015 10:07 AM

I purchased this more to disable the fuel management program and recalibrate speedo for larger tires, but decided to do the full tune. I am very pleased with the outcome! The truck doesn't lunge while downshifting (because of AFM), it shifts smooth and confidently, performance is improved, gas mileage stayed about the same as w/ AFM, and it doesn't require 93 octane. Even w/ an exhaust system and cold air intake, the tune went smoothly and never any check engine lights. Very Happy!
