Thread: GM vehicles with AFM
11-24-2012, 04:42 PM #11
Nor am I looking for an argument. *You* stated that *you* have concerns about uneven heating, and having that exacerbated by staying in V4 mode longer. I simply replied saying I don't think it's a real concern. You then replied stating it is, though also stated that there is a lot of speculation on it. Either it's a real concern, or there's simply a lot of speculation. I just want the facts, as I'm sure anyone else would who was interested in knowing about such concerns, and how it would relate to this product.
GM's choice of programming for when to switch to V4 and how long to stay there is mostly the bare minimum to meet the CAFE standards.

I'd be running a little attitude as well. Needless to say, that is not the customer Service you want when buying something that is "one-of-a-kind"Ray

So back to the original question. When should one expect to see some sort of reply after having sent a PM and/or e-mail?

I also have sent a PM on this product called the "Range" I did receive a PM back but nothing to get any contact info ect. I am interested in trying this product out as I feel that I would benefit some with having the AFM stay in just a little bit longer provided that there are no issues. I think that the tuner companies should look into this making it a user adjustable variable if there is no danger in changing the time it stays in V4. With myself having 35" tires I only see the v4 mode advantage at 30-40mph.

Oh I know, not worried about it. The old Envoy used some, they all seem to.

Does disabling AFM actually fix the oil consumption problem? If yes, there are a bunch of after market tuners (Hypertech, Diablo) that will let you disable AFM.
When I had my old 2008 Silverado it used to use about 1/2 to 1 qt every 6K miles with AFM functioning. I only have 1600 miles on my 2013, but time will tell.
