i have a 2015 hd3500 dually with remote start, is there an option to change the duration of run time before shutting itself off ? it only runs for 10 minutes and then i have to restart it. it is the factory option from gmc. also anybody else notice when heat or ac is on high and you open the door that there is a severe "popping" sound. i guess this is from the positive air pressure in the cabin.

I haven't found where you can change the time limit. It's also 10 minutes for my '14 1500. For a gasser I know 5-10 minutes is just right, but for the Duramax I would have set the timer longer being a diesel.

 

As for the popping sound, I haven't noticed anything like that.

If you have a engine block heater for the diesel, you shouldn't need longer than 10 mins. My duramax gets warm within 10 mins.

If you do the remote start process again while the remote start has been activated once, it should keep it going for 20 min. After that it will no longer allow a remote start until a certain time limit has passed. Should be in your owners manual regarding that.

 

FYI- The Block heater will not work at temps above 30F or right around there.. it has a built in thermostat in the cord. Not sure about prior to the LMMs, but on my 08LMM it said in the owerns manual that the glow plugs and engine is advanced enough that it does not need assistance from the block heater for starting and fluid warm up at temps above that 30 something threshold, so you can plug it in at night but unless the temps get below 30 or 32 or whatever the threshold is, the block heater will not come on. Now, when it does get below that temp and the heater comes on, yes you do notice a slight difference in time it takes to heat up but regardless they are good engines and do quite well in the winter. (This is with regards to the Duramax, not sure about the gasser)

You can extend the remote start 10 minutes more by doing the remote start procedure again while its already running. You have to do it before it times out or it will shut off and you have to start it again. Only lets you do it twice before having to put the key in the truck.

There's no plug for my engine block heater. Works on startup.

Yep, but make sure you wait until the time is almost out as you only get 10min. more once you remote start again.

They are zip tied up along the engine I think, passenger side towards the front of the engine.

The coolant heater plug is on the passenger side, generally near or under the battery, tie wrapped so you may have to feel for it. Use a bright light. Then stretch it as tight as you can and you can usually end up running it to just outside the grill if you so wish.

      OCI, not when but why?

      By Atlas · Posted

      On the subject of OLM, Gm's OLM tool may be more "informed" than others brands. I recall OLM's in mid-2000's Chrysler products literally counting down a set number of miles. That's all the OLM appeared to be.    I would actually expect GM to be able to explain the parameters that their OLM takes into account from a high level. No, I would not expect them to disclose their software coding or data analysis around their parameters.   So we're talking about two different topics, so to continue the subject on the other one, I'd be curious to know how much "standard particulate matter" in fresh oil is able to be filtered at first start by a fresh oil filter. How much particulate matter is enough to "matter"?   I.e. how much of a "lever" do we think this equates to (variability in particulate content, in fresh oils, between different makes/brands, some which filter less, and some that filter more).   We can say that more particles = more wear = shorter engine life as a logical statement and use that data with a little marketing to scare people into selecting a more refined/filtered oil. Using a similie, is this like deciding to forego two alcoholic drinks in a lifetime because we're worried about the potential impact on lifespan? Are there numbers which translate the ISO test results into a quantifiable increase in wear for a given engine/use case?

      I'm pretty sure it doesn't actually recalibrate the speedometer it just changes the wheel speed sensor inputs to the computer. The truck still thinks it has stock tires.

      I apologize, I missed this post, at risk of going off CURRENT TOPIC.   I'm not saying it is BS, I'm questioning how much information is being held back. GM is NOT going to spell out exactly every parameter in the algorithm. Liability, intellectual property, etc.    I'm not naive enough to believe that it is as simple as revolutions, coolant temperature, miles, time; are you?    I don't do irrational either, and boiling the OLM down to four simple values that I could code in an afternoon (I'm not a coder) is irrational - unless it suits your agenda to ignore it.

      Chris 21 I appreciate your constructive response. !!  😉😉😉   The 6.6 is gas.  Correct me if I’m wrong but by recalibrating the speedo you’re correcting the shift points of the transmission on these trucks.?.

      That is a huge misconception.     Bigger does not always equal safer.  Modifying does not make it safer either, with exceptions.   Think of this.  Your truck in stock form is capable of emergency maneuvers, proper stopping distances, its handling is designed around the factory wheel/tire packages, etc.   37s and a lift?  Now you've affected your braking distances, handling and ride control.  You've raised your center of gravity higher.  Your front visibility is now obstructed more than stock, same for your rear.  Does it look cooler?  Yes.  Does it now work as good as it did from factory on road?  NO.       As for my mention of exceptions?  Say you had a sedan or crossover.  They typically come with all season tires.  If you swap out for a performance all season or a summer tire, you improve your car by lowering its stopping distance (better braking because of traction) and improve the handling (regular and emergency) of the vehicle.  That is an actually improving modification.  My old 2019 LD 1500, I ran UHP all season tires on 20in wheels in a factory offered size.  It improved all aspects of how it drove over the Duratracs it came with from the factory in the stock 18" tire.
