Unless youre on flat terrain the cruise is not your friend while towing heavy with these gassers. It doesnt have the predictive ability to compensate for a drivetrain that hasnt got reserve torque. I did notice on my 2021 6 spd that the towing sweet spot is around 64 MPH. Over that the torque becomes a bigger issue and it picked between gears more with much lower MPG.  Since thats typically the MPH I run its a non issue for me. 

As for the adaptive cruise I likely wont even try it on the truck. We have it on our Equinox and I leave it off. Too many braking and harder accelerations than I would use. It lacks the ability to think ahead, I try to stay ahead of things and coast rather than brake. I think on balance it actually drives the car harder than I do. 

I will have a Scangage 3 on my 2024 before I tow with it. The gauges (oil, coolant temp and Volts) are wholly inadequate and I believe designed by someone without any serious large pickup experience. The lack of an actual numerical value is unforgivable. They should ALL be like the trans temp gauge that can be placed in the center of either side. I noticed the Volts goes away when my truck is placed in Tow/haul ?  Who greenlit thats mistake ? Its already an inferior gauge but when I need it most its gone.

I tow our race rig (10,500lbs) with my fathers 6.6 gas 6 spd and not for nothing Ive never once wished it had more gears. It rarely revs over 2500rpm at 70mph. Its pretty hilly around here too.

Just curious, what gear ratio is your truck?

Agreed on the gauges on all points.  I found myself looking for the voltmeter when towing too to see what it said when I'd get a "check trailer wiring" message.  The digital gauges on my 2016 Denali were less customizable yet still far more useful than these.  Hoping a software update will make this cluster more usable.

For whatever its worth I flamed the gauges (or lack of) when GM sent me the survey about my truck. From what I hear my sentiment is pretty widespread. I dont hold much hope for a substantive change though. I think the more likely scenario is they get a mid run update and leave us in the dust to fend for ourselves. Nothing the Scangage 3 wont fix. 

 

On another note. I drove our new Equinox last night for the first time after dark. I am impressed with the LED headlights but I have to say I love the automatic bright light switch. It works flawlessly. 

I am pretty sure the lights on this vehicle might be a little harsh on the people in front of you. I noticed a number of times that people were tapping their brake lights for no reason other than I think they figured I had my brights on when I didnt.

Having just come back to gas from a 6.7 Cummins I will give my 2 cents. 1st off I loved the Cummins but all the emission issues and dash lights slowly drive me insane LOL. Anyways I traded it for a 2020 Chevy 2500 6.6 gasser. I love it. It tows my 9-10k camper nicely. I love the 6L90 6 speed. It's a fantastic transmission imo and does great towing. My rpm towing 65-70 is around 2300-2500. It only downshifting on a grade and then it's around 3k. I lock out 6th because that will just build up extra heat. 

 I also have a 2022 F250 with the 7.3 Godzilla motor and the 10 speed. It was bought to be my retirement truck to go see the country in a few more years. However there are so many cases of lifter and cam issues with the 7.3 that I ordered a new 24 gmc. If you don't compare the gasser to diesel then you will be happy with the 6.6 gas in my opinion.

I tow a toy hauler weighing 12k-13k through the Rockies with my gasser. It does just fine. No WDH either, just bags. High RPM is expected. Been on 8% grades with it.

I don't wish for more gears either. But I will like the added torque from that Whipple SC as soon as they officially add support for my 23'.

I am still completely stumped at why someone would greenlight a dash design that makes the already virtually useless voltage gage disappear when the truck in in tow haul mode ?   To my thinking voltage is one of the top 6 things that need to be monitored when towing, I have a ton of lights on my trailer that are now part of the load. This really illustrates what I have been complaining about with GM not putting a serious truck person in charge of the dash instead of some art school graduate thats never driven anything bigger than a Trax.

Did you get your scan gauge 3 yet?

I have to wait until next month to get it in the budget, The RV is getting a new Dometic 320 first. Priorities 😎

Sounds like the 6spd is still great for towing and they just missed the programing with electronics on the 10spd maybe?.......haven't had a chance to tow yet....only some pretty heavy loads in back (which is primary reason for me).

 

1/2 tons and 3/4 tons aren't even really comparable in way they feel driving.....totally different in every way

Glad to read this. I just moved from a 2023 1500 AT4 with the 3.0 to the 2024 2500 AT4 gasser for my 30 foot travel trailer. The wind was too much Nebraska’s for the smaller truck. I hope the 6.6 does about the same as the 3.0. The 3.0 drank def like crazy - less than 900 miles a tank though I think I had a def gauge issue.  
 

Did the 2500 solve all of the handling issues with the trailer compared to the 1500? Trailering across Nebraska and South Dakota with 20-30mph crosswinds even got me wife approval for the upgrade with the expectation that the ride will improve.

I run a ProPride hitch and put load range E tires on my half ton along with Roadmaster Active Suspension, so I never had issues in crosswinds.  I mean the whole rig would move around but it never felt sketchy.  I still run the ProPride hitch on the HD but with far less weight distribution than before.  It's considerably more composed in crosswinds, going down mountain grades, etc.

I can't get over how big and bulky the ScanGauge 3 is... making me think about getting the new Edge CTS3 unit since it is slimmer and a little better layout.

Edge CTS3 is almost twice the money the SGIII. I'd need more than a 'slightly' smaller footprint. 😏

I’d never heard of this one but they both look like black garmin gps units to me? And I concur with grumpy. That is literally over twice what I paid for the sg3 for the same functionality. Not sure how long that edge company has been around but I believe the sg has been making the gauges since the very early 2ks.

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

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
