If you're willing to hose your warranty I found the BEST setting is to disable it in the tune below 65mph. That's what I do. That way on long highway cruise it kicks in but doesn't annoy me in town, doesn't growl, doesn't shake the belt, none of that nonsense. Basically you're looking for the "MIN VSS" setting if I recall correctly.
It's the best of both worlds and the way GM -should- have done it, but doing so will void your warranty.

Be aware that the Range AFM module constantly pulls power even with the car off; the mfr recommends that the device be unplugged if your car sits idle for more than a week or so. It's possible to install an off/on switch with the device so that you're not constantly inserting and removing the device.

The revisions they HAVE made were to eliminate, or reduce, instances of a CEL.

Not according to the device manufacturer. They still recommend unplugging it if the car will be not run for a week or more.

I have no idea why anyone would want to pass up such a wonderful and generous opportunity from the General.

Range AFM battery draw
As they put it on their current and website:
Support
Battery Draw
The Range Device does NOT draw much on the vehicle battery during normal operation. If you drive your vehicle daily (or almost daily), then this will not be a concern. However, if you drive your vehicle infrequently (i.e., only on weekends), please remove the device. It is best practice to remove the device if your vehicle will sit for anything longer than a week.
To add some more detail:
- The device will go to a VERY low "sleep" state after the engine is off (within 3-10 seconds of the engine shutting off)
- In this state all the LEDs are OFF and it hibernates at about 1-3mA
- Every 7-25 seconds it will wake up to a "light sleep" state to check to see if the vehicle is running. In this mode, there will still be NO LEDS lit but current draw will spike for < 0.1 sec to about 7-10mA.
- If the vehicle is NOT running (i.e. RPM < 500) then it'll go back to deep sleep. Rinse and repeat until the vehicle is running, at which time it'll fire up completely and you'll start seeing LEDs light again.
A healthy battery with decent capacity should be able to go much longer than the recommended length of time but it worth it not to come out from a 3 week vacation and find the battery dead in the airport parking lot!

Safety Car
Try the Search function (your friend)
A DS 'tuner' will not run down your battery so you can forget about it and if you remove the tune before going in for "any" type of service you will not have any problems. Like I said, do a search, you can use the tuner just to remove the V8/V4 mode from the stock tune if that's all you want but go to their site to check things out before buying.

Changing a tune? IIRC, that will void your warranty.

As part of this beautiful V4 technology GM includes a special feature to ensure that your torque converter lockup clutch doesn't last too long by continuously modulating it on and off during V4 mode to reduce the transmission of engine vibration to the rest of the car. This ensures that you will get to visit your GM dealer during warranty to have the torque converter serviced and then it is even better after the warranty runs out because not only do you get to visit the dealer for the exciting torque converter repair you also get to pay for it.
