Range Technology
Hi everyone:
I have a 2017 C7 base stingray with the A8. My wife primarily drives the car. After reading on this forum issues people were having with their A8's and the AFM system I purchased the AFM disable module from Range. I also purchased OBD1 on/off switch cord. My question is this. How did you guys/gals, install it without having a cord hanging down and still being able to conveniently use the switch? My wife is already annoyed about the need for the switch (this is her car), I am trying to make it as effortless a process as possible. Thanks for the help. |
I think you overreacted.... I have several friends that have the A8 and have had zero problems in cars that have already accumulated more than 60K miles.....
Yes, I know that wasn't an answer to your question - jus' sayin'..... |

This is now the 5th range thread on the home page. lol

Yea, there are a few of them. Do try the search. I would say though if you want to make this as easy as possible, eliminate the switch. Review this post, someone used the switch lead that you have and tied it to an accessory power so it just turns on and off with the car.

I did do a search before I posted. I only saw postings about how Range works, the pros and cons, etc. Unless I missed it I did not see any postings about what I am asking. I did review the above link but I did not want to make any modification if I can help it.

I posted some where asking how people have mounted theirs. I'll try and locate the thread. I used velcro and tucked everything up on the panel by the port. It's out of the way and easy to reach

Right get on top the obd2 port using velcro. But I have since gone to a relay setup, no switch! How To: Range AFM Disabler – No More Parasitic Battery Drain via Relay in Cord Also waiting for a forum member to post a review of the Diablo equivalent unit to see if they solves all the Range issues. |

Draped the cord over the steering column. The switch is right on top. Plug and play.

Why doesn't the manufacturer just redesign this thing with an on/off switch? problem solved..

I think I am going to stop using this altogether. Yesterday, I took the car out and other than going in reverse, the car stayed in D4. No matter what I did it stayed in D4. From researching this forum I know others have had this problem also. I did not get any CEL's but i ran a OBD1 scan and noticed some permanent communication codes. After restarting the car a few times, the car would go into different gears. However, it seems like the car spends a lot of time in 4th gear before shifting down when slowing down. I can't recall if it did this before, but I think I would have noticed it. Is this normal?

The car normally will stay in 4th gear until a very slow speed and under light acceleration it will upshift into 4th between 21 to 23 MPH (depends upon your rear axle ratio); it will hold 4th under deceleration to much lower than this speed range before downshifting to third and then directly to first as you come to a stop. Currently for 2016 or later (maybe the absolute latest version works OK for 2016 models) the best solution is to either manually turn on the Range module a few seconds after the car is started or build the delay relay circuit so that it automatically turns on a few seconds after start. It is an inconvenience but it still beats the hell out of GM's screwed up V4 torque converter strategy with its associated RPM fluctuations, wear, and ultimately shudder. I would much rather deal with switching on the Range module when I am not using manual mode instead of dealing with a disassembled C7 while the dealer service tech hopefully does a good job of replacing the torque converter and getting everything back together again only to be repeated again in the future. I wish Range had a module that worked perfectly with no user intervention but for now it is something I will deal with in order to have full automatic mode without the downside of V4 mode. |

What you experienced is typical of what happens when the Range module causes a communications error between the ECM and TCM at startup. Fourth gear is the default "limp" gear for the A8 when it cannot establish communications with the engine which allows it to protect itself during shifts. If you remove the Range module and do a restart you should instantly get all of the gears back or you can unplug the Range module, start the car, and then plug the module in while the car is running which will reset the error codes.

I noticed when turning on the Range that it takes about 5-10 seconds for the blue light to stop flashing and go solid. I start the car, let it idle down then switch it on. When i park I turn it off before shutting down. Haven't had one problem with mine, works perfectly. Running in V-8 for 1200 miles last week noticed fuel economy at 27 as opposed to 31 with Range off on previous trips. I do use the throttle so no hyper-miling for me.
