You're entitled to your opinion.. but don't forget a big part of this forum is customizing/modifying owner's trucks exactly how they want them.

 

If you have HIDs in anything but the Sierra SLT or Denali, permanently disabling DRL's is highly recommended. Using the knob to kill them often means a quick start up then switched off, which is bad for the HIDs.

In my truck the Auto DRL's only come on when put into gear so how would that put a load on the hid when starting?

I don't mean to offend anyone but just don't see the point in adding a feature that already comes with the vehicle?

not starting a heated debate just asking questions..

"I was a firefighter for 30 years" sounds like a qualifying statement.. if not intended that way, my mistake. And I never said you were evil. I clearly stated "everyone should be free to choose if the

Why? They're for safety. Not sure if you've ever seen the result of a head on collision... I bet you would change your tune if you did.

I'll take paying for a bulb over getting smoked by someone that isn't paying attention any day. Lots of people are too clueless to turn on their headlights in low visibility conditions.. I personally

I gotcha. I think it just comes down to convenience. A lot of the auto features on the truck aren't necessary and could easily be done manually but we still like them automatic. With DRL's, members just want the choice whether or not to have them auto on.

FYI I can program those out of the BCM.

I bet it's not cheap and you'll need my ecu?

 

Im curious to know what hardware and software you're using to program.

I wonder how difficult it would be to disassemble the headlight switch and remove the spring feature that prevents leaving it in the OFF position?

You lose the auto on feature because your essentially turning off the light system.

I think my 99 1/2 GMT800 had a position for OFF. If so, it'd be interesting to see if they are interchangeable.

Well if your like me and the truck is parked in the garage all the time then it would be a benefit as I have HID's as it dark enough for it to trip the headlight sensor to make it think it is dark out. I just leave them on when it is parked in the garage, but when it sits out I turn them off.....when I remember to.

turning the headlamp knob to the far left will cancel all running lights (headlamps included) when desired. of course you likely knew that.

 

there are times when I turn mine off but seldom, just too easy to drive as designed and live with it IMO. after all, its likely only you that will be aware of them being turned off or even disabled.

Anyone ever figure how to disable DRL's? Does a tech have to do it through BCM and will they do it? Thanks

A tech can't do it but my company can through custom bcm programming.

If G (wire) in the headlight plug runs the DRLs, couldn't you install a diode in that wire to render them off all the time..........or (cut the wire and tape it up, if you desire)....?

 

Also, the wiring manual shows G to be the wire on both plugs (right/left)....

      Some Assembly is Required

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.

      Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.

      Software Update

      By Chuck FB · Posted

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.

      Software Update

      By Chuck FB · Posted

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
