Making even more progress! HMI has been updated to the newest software, which means Wifi compatibility ! OTA updates are enabled, meaning you will receive all future software updates for the HMI over a valid network connection! Also, the ability to download apps from the shop

That's awesome!  I just ordered my 2.5 hmi on Ebay just now. Cant wait to get this installed.

For anyone interested I believe I will have the ability to do programming very soon. I have made quite a bit of progress and hope to have the reprogramming method refined and ready within the next few

For anyone following along I am once again waiting for parts. I was having issues with the radio module I had originally ordered. A new module is on order and should be installed and ready to go by the end of the week. Once I have full audio for everything I will make a post here, signalling we're good to go! 

 

Again, thank you so much for your patience in this. I appreciate it!

Curious question, What module owns the different color combinations between Chevy and GMC? Is that programmable to whatever module you can get your hands on?

Color combos in what aspect? The colors on the screen? 

 

For the most part, everything you see on the infotainment screen is handled by the HMI. From 2017-2018, GM scrapped the red color scheme and made everything chevy blue, regardless of if the truck was a sierra or silverado. That's why in the new screenshots the scheme is blue. They did this with backlighting and cluster colors as well.

GMC still had red lighting in 2016 and Carplay/AA was already out. So finding a 2016 GMC 2.5 HMI is needed to maintain the red GMC lighting.

Correct, if it bothers you that much. Personally I'd prefer to have the updated interface.

By red lighting do my mean on the clock and temp at the top of the screen or is there more to it? I'm guessing this doesn't mess with the dash lighting.

Yes, plus the general radio/phone/nav/weather layout will also be in the blue theme.

That's not a deal breaker then. I don't even notice what the screen looks like half the time but I like the dash accents in red. Didn't see any reason this would affect them but had to clarify.

The HMI can be updated to an older build with red accents but you will have older software and the circle icons. It's your choice!

I forgot to ask this Monday, what are the odds that the bad module was an isolated issue and you wouldn't run into it with one that we provided?

That's what I'm trying to figure out! I have a strong feeling the module I have is defective, however I need a second one to test against to make sure everything is working out as it should.

Just trying to understand the situation. What exactly does the radio module do? Is it just a tuner? To make CarPlay/Android Auto work with our trucks do you have to program anything other than the new vin? ( regarding radio module only)

The Radio is responsible for all things MOST. It is the MOST Bus master. It is kind of like the middle man between every module who uses a form of media on board.

 

It also has hardware in it, like an XM receiver, AM/FM tuner and HD Radio module. 

 

As for what the EXACT change that happens in the HW between a 2014 module and a 2016 module, I can only assume it's either a calibration set in newer modules to allow ACP and AA to work properly or a physical change in hardware. I don't have a concrete answer for you unfortunately.

That explains a lot, Thank You. I did have to google most bus master lol

      Sugar Bears 2015 GMC Terrain SLE-2 2.4 AWD

      286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔

      cam upgrade in CA

      By AidenVorpagel · Posted

      hello I recently bought a 2012 gmc 1500 with a 5.3 and have a AFM disabler on it I'm interested in doing a cam but I'm worried if I remove the AFM system I will fail smog does anyone have info if they are able to detect that or a work around to it (not talking about hot smogging) please let me know thank you

      Possible lifter tick after DOD delete

      By B14Sierra · Posted

      Update. I started chasing down my symptoms. Started first with pulling valve covers and looked at everything. Everything looked good and couldn't hear or feel anything different. Then a compression test. 240 psi or really close on each cylinder. I was worried I was a tooth off of timing. Not bad for an engine with 173,000. Granted I did put new heads on. I sprayed water around the injector area to see if I could hear a change. Nothing. I hooked up my new hp tuner which I should have done in the first place but I don't really know what I'm looking at just yet but am learning. I noticed the fuel trims were way off so that told me I have to have either a bad injector or exhaust leak. New injectors, so I did the shop vac on blower and in the tail pipe. Sprayed soapy water and found the exhaust flange on the drivers side was leaking. I didn't think it would be that considereding I pulled the heads and left the manifolds attached. I did have the transmission replaced not long ago. They must have not seated them properly but I guess I didn't notice. I put in new gaskets on both sides. Which by the way isn't a bad job but I had a hard time getting them to seal right. Took two attempts. Reset the fuel trims and the ticking is gone, engine runs smooth and acceleration has improved. Got to feel the real difference with that stage 1 cam. It's not that big of a difference but it does add a little more. It feels like how the truck should have been from the factory.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.
