Dumbed Down Dic

Although I'm generally pleased with my 2008 LTZ 3500HD over my 2003 LT 2500HD, I'm greatly disappointed with the DIC.

 

At least 8 features were stripped out, and just one added. The "addition" was to put the tranny temp gauge into the DIC, replacing the previous gauge on the dash, in effect a net LOSS even for that function.

 

Then to add insult to injury, they moved the DIC control off the steering wheel to an inconvenient spot on the dash.

Yes, I'm very disappointed in DIC in wife's new Denali -- are you listening GM!!!

 

Love the fact that I can watch instant economy on my truck as I drive down the road.

 

Of course some idiot probably was watching that instead of road, then hit someone/thing, then sued GM for putting that feature in their truck (hello, personal responsibility!!!).

 

GM: Bring back the fully functional DIC!!!!! PLease.

What all is missing? I guess I am just ignorant of what they used to have but mine seems pretty informative.

 

Funny how you never know what you're missing until it gets pointed out! Now I wanna know!

Search for DIC on 2004 trucks. Mine can show the following (and I'm sure I'm missing something from this list)

 

- standard stuff like odometer, hour meter, oil life remaining

- instant economy (i really like this...up hills = 3-4 MPG, down hills / coasting, 45-50 MPG. Interesting to watch as I drive)

- miles remaining on this tank of fuel

- current MPG for this tank of fuel

- gallons of fuel consumed

 

Oh, that's all I can remember for how. Someone help me finish this list...

That's odd. My Sierra Denali has most of those, but not the instant fual economy. For some silly reason, GM seems to only have the instant fuel economy activated on engines that have AFM. Why they don't give you access to that info is beyond me. You know it's in the computer. So, let me see it!

I agree with this totally!

I use my DIC more than I use the cruise control.Why not put the cruise control switches back on the turn-signal stalk like it was for years on GM vehicles :bs:

And while I'm at it......the headlight hi-beam switch....why do they now make you push the lever forward to turn them on,and then pull it back to turn them off,instead of the old way of pulling it back to turn the hi-beams on & off? :crackup:

Yes, I'm with you there. Blame the Japanese for that, that's the way all their vehicles are, just like the different style electric window switches. After 2002, everything went to the Japaneses style. I'm used to it now but when I get in my wife '98 Buick everythings back to the old style switches. :bs:

Between my 2003 LT D/A 2500HD and my 2008 LTZ D/A 3500HD the following DIC functions disappeared:

 

"Instant" MPG

"Annual Miles" odometer

"Business" odometer

"Business" fuel consumed

"Business" MPG

"Personal" odometer

"Personal" fuel consumed

"Personal" MPG

 

Maybe some other stuff I can't think of right now.

My '05 doesn't have any of those options either... so they (GM) eliminated those things several years ago...

my dic has all of these features plus some, I do agree about the location though

No instant economy here, pretty sure that went away sometime around the '05 MY trucks. I like the DIC, it's quite handy. The best feature is the tire pressure for each of the tires. If they got rid of all that other extra stuff (like how crappy my mileage is) and just kept the tire pressure monitor info, I'd still be very happy. :)

I heard about that loss of features. Weird usually its the other way around, the newer it be the more features. I wish I had the instant fuelk economy thing though that looks pretty cool. Most C6 Corvettes have it now

      No 12v outlets in 2026 gmc Sierra

      By PhilB · Posted

      It is possible to add your own 12v outlet to your truck.  Check out this video:   I verified via GM Upfitters that pin 31 is the same on the 1500 trucks.  The wire is GM part number 84779405.   You can get the GM 12v outlet from Amazon  https://www.amazon.com/Genuine-Accessory-Receptacle-25774623-13549530/dp/B0F1H9YRGF EWAY 12 Volt Power Adapter for GM   https://www.amazon.com/EWAY-Chevrolet-Silverado-Cigarette-Ignition/dp/B0915RRW6Q/ref=sr_1_1?   I just haven't figured out a good place to put the 12v outlet in my truck.   Some people are getting USB-C to 12V adapters  https://www.amazon.com/WYMECT-Cigarette-Lighter-Socket-Adapter/dp/B0F87WNQKB/ref=sr_1_1_sspa? Not sure if they provide the correct amperage that a device like a tire inflator would need.

      Wiring Help, Please

      Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      By Grumpy Bear · Posted

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
