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.

Interested in it shipped to 28327.

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! :thumbs:

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..

      2027 GMC Sierra: Official Discussion

      By Jsdirt · Posted

      Spot on. The government makes ridiculous mandates, and this causes manufacturers to jump through hoops for every TENTH of a MPG. Main reason quality is in the toilet and prices are in the stratosphere.   The gov't tightened the MPG requirements so much 5 years ago that the only way manufacturers could meet these absolutely ridiculous numbers was to go all EV. Hence the push.     Nobody hates good MPG, Atlas - nobody is "whining". Your side has that trait all locked up. What a stupid argument attempt!   What I particularly hate is the government meddling in the free market system. Had this system been allowed to work as designed and intended by our Founders, cars and trucks would be hitting numbers that would blow our minds, all while costing 30% LESS. Not only that, but engines could probably hit 150k miles again without needing major internal surgery.   My forty year old Ford 302 has 312k on it. Wonder what changed?🤔

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By revmanii · Posted

      The BORA 3/8" spacers arrived yesterday along with the extended lug nuts. I got the front wheels changed out today, but was overheated and covered in sweat so bad, I figured getting both front wheels done was a win, and took a cool shower. Hopefully, I'll go out tomorrow morning before it gets into the 80+ temps and do the backs. After getting the first wheel snugged up, I backed out one of the lug nuts then hand turned to count threads. I believe I stopped counting around 12-13, so I think I'm good there.

      My fullsize truck is averaging over 26mpg so I'm pretty happy with the increased fuel economy targets. When I had my gas Silverado (2020 5.3) it was averaging 21. Again, for a fullsize truck, that's very different from the 12-15 these things used to get 30 years ago.   Whine all you want, increased MPG is a good thing.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That is a fair point, and I think an OBD-first proof is probably the right next step. I agree that the value is not the hardware box by itself. The marketable part would be the software: always-on capture, baseline learning, event reduction, system-specific reports, and alerts. Also agreed that if an OBD device is always plugged in and has local storage, it should not miss the event in the same way that a scanner plugged in after the fact would. The only thing I would not want to assume yet is that an ELM327-class device gives all the late-GM data needed at the rate needed. Standard OBD live data, DTCs, freeze frame, Mode 6, VIN, and calibration information are definitely the right starting point. GDS2 also proves that a lot of useful ECM data can be viewed through the DLC without needing a DTC first. The question I need to test is whether the data needed for a useful GM V8 event report is actually available through the DLC, and at a useful sample rate: - misfire counts / roughness by cylinder - AFM/DFM state - oil pressure and oil temperature - fuel trims - voltage / reset context - U-codes and communication events - calibration / software information - whether these are standard PIDs, enhanced DIDs, Mode 6 data, GDS2-only data, or not available So I think the right benchmark is: 1. Build the OBD-only version first. 2. Keep it plugged in and logging locally. 3. Compare it against GDS2 / freeze frame / HP Tuners or another higher-end logger. 4. Measure which parameters are available and at what update rate. 5. Only justify ECM-side hardware if it captures useful evidence the OBD version cannot. So you may be right: the consumer product might simply be an always-plugged-in OBD event recorder with much better reporting. A question for you: when you say ELM327 devices can already deliver all the data needed, do you mean generic OBD Mode 01 data only, or GM enhanced data as well? For a useful GM V8 report, would generic OBD data be enough, or would you expect the tool to include enhanced items like misfire by cylinder, AFM/DFM state, oil pressure/oil temp, U-codes, and calibration information?
