Range Technology V8 AFM Disable Module

yea I would use a voltmeter and check it at park and then when you come back out in the morning to confirm if it is the battery or not.

Thanks, I might actually just get rid of the Range unit. I've been driving without it the past two weeks and really can't tell much difference other than seeing the V4/V8 on the screen change..

Keep eyes peeled for a for sale thread.

IF they have the oil burn/lifter issues properly fixed, you should be ok running a sometime 4 cylinder...

I was not really concerned about that issue. I'm confident the AFM issue has been resolved in these motors. It flips back and forth between V4 and v8 flawlessly. I just wanted to try the unit for a while to see how it operates in V8 mode all the time. Putting my Range unit up for sale today.

My inside sources tell me that was fixed back in 2010/2011. Also my boss has a 2011 Tahoe with 132,000 miles on it mostly highway which is when V4 mode is mostly engaged and he's not consuming a drop of oil. Also remember GM puts AFM in every truck engine now on the 1500's, not just the 5.3L. That's a lot of trucks on the road burning oil if it's still a problem which leads me to believe they're confident in the fix as well.

Bingo. Which is why I am not concerned!

Yes that is what I have been told. Late 2011s on. Hope you/they are correct. If I replace my 09, the afm will be tuned to stay off. I am waiting for sure till these new engines have plenty of miles. Once one pays 45,000 for an oil burner with a trans that is programed for crap, one is a little gun shy.

I kind of wish I knew about this range unit when I still had my 2007. I love my 2014 but the 2007 was paid off and $200 for this unit may have solved my oil consumption issues. At least buy me a couple more years while they get the kinks worked out of these newer trucks. Oh well hindsight is 20/20 and can't go back now.

I hear ya. I would have done the same or tuned out afm if I had known. But the oil burn issue hit like a wave. Suddenly the GMT-900 trucks were drinking oil. I too think they have solved that problem. However I will wait, unless the stage one fix on my 09 does not work. Will be waiting just to see what else may pop up on the '14s. Ford has had serious issues with the variable cam etc...Figure GM will have it right..

Besides the 09 oil burner, I also have a '90 GMC suburban that was painted twice by GM for bad paint. Neither repaints did any good. Just gun shy right now. For our run around when in town cars, we have a V-6 accord and a TSX. Both have over 100,000 miles. Each doing just fine for now. But trucks and fast rwd cars are much more fun.

My 1996 Silverado with 175k miles drank a quart of oil every 3-4k, and it didn't have AFM. My 2003 Yukon with 170k miles drinks a quart every 5k miles and it doesn't have AFM.

Just saying...

Those are just old motors yo...prolly got some gaskets leaking.

Nope, neither one leaks/leaked any oil. The 2003 is clean as can be on the outside. The 1996 did start leaking up front and from the pan, but I replaced both gaskets which fixed the leaks. They both just burn a little oil, which is my point. Older engines tend to do that. I'm not convinced that AFM is cause of ALL the oil burning problems as people claim.

My guess would be the oil rings, or the valve seals. Compression may test good, but the oil rings or valve seals could be leaking..
