RANGE Technology AFM Disabler - plugs into OBD port - Chevy/GMC.
SOLD.
I bought this new a few years ago for my Denali. Works great! I sent it in to RANGE Technology for a ‘update’ early last year (but I believe they just switched mine out with a newer/updated one). I’ve since bought a tuner to tune out the AFM and no longer need this.
Keep your vehicle in V8 mode; Disable 4 cylinder mode on all GM Active Fuel Management Vehicles
Installs in seconds; Plugs into diagnostic port with no tools needed
Does not reprogram factory ECU; Leaves no trace
