With gas prices the way they are I'm sure some people will opt for this.

I agree, did not buy a high performance vehicle to have it run in V4 mode, would have bought a Camry. The reason to buy a Range Device to keep it out of V4 mode is to improve performance and do away with the shudder that is created from jumping back from V8 to V4 mode and to prolong the life of the lifters, engine, transmission and torque converter by taking the AFM out of the operation of the vehicle.

Quite a few threads on this forum about the use of an AFM disabler device, specifically Range, mostly positive.

There are times you want to save money and times you are willing to spend it. Paying this much for gas kind of feels like punishment. My GS is my spare car so it’s not such an issue but for folks who daily drive their Corvette I can see how saving some of your weekday gas money to allow for more gas money for the fun times might be a nice option to have. As performance cars go the Corvette is pretty good on gas but if you are paying $5-6 a gallon and are stuck in bumper to bumper traffic that’s going to get your attention.

If AFM can cause shudder, TC and valve train damage when operating some of the time imagine what it can do when operating most of the time! All for the sake of a couple of miles per gallon? Is it just me or is this just *** backwards?

I just checked Range Technology website to confirm that this is a real thing - yes it is. Correct name is Range AFM+. Claims to keep your engine in V4 mode up to 80% of the time if cruising with a light load. Seems to me this would be MORE detrimental to your engine than occasional V4.
NOT something I will do, I'm keeping my Range and running V8 100% of the time.

Range + may work for some, but I installed the Range AFM Eliminator to keep the car out of V4 mode - when I drive it I want V8 all the time.

Same here, with a Borla X-pipe and a NPP fuse pull, quite happy with the exhaust note.

I'm not sure what can help you in bumper to bumper traffic except a hybrid or electric car. Does AFM help much other than cruising? If not, it won't matter if you are stuck in traffic. I think later on, I will get the ECM reprogrammed to have the AFM out so I don't have to deal with the AFM clearing codes all day long.

Question: What do I do if I have to do an emissions test?
Answer: As with any device that plugs into the OBD2 port, you should REMOVE THE DEVICE AND DRIVE IT SEVERAL TIMES/MILES before taking it into the center for testing. This will force the vehicle to reset all the "OBD2 READINESS MONITORS" and to be prepared for the emissions testing (whether it be on the rollers or just an OBD2 "sniff" test).
The Range module doesn't affect emissions but because we take control of the AFM system, the vehicle may have an OBD2 Readiness monitor show "Not Ready" because it wasn't allowed to run (no V4 mode with the V8 module, for example). The easiest thing to do is just unplug the module and run the vehicle a couple of days without it to be absolutely sure that everything gets a chance to run.
Another good thing to do is top off your tank and drive 50-100 miles total before performing the test (this has nothing to do with the Range module). This allows the EVAP system to perform a proper "purge test" and pressure cycle, which will allow the EVAP OBD2 READINESS MONITOR to show "complete."
