Has anyone installed one of these? If so was the connector wires under the dash hard to get to? I’m going up to 34” tall tires is this the best option? Thanks

Pretty much the only option unless you wanna spend $$$ on an ECM swap like HP Tuners or the 3 new entries to the market with Diablo/SuperChips/Edge.

 

Word of caution with the Hypertech inline.  If you have to have ANYTHING reprogrammed on the truck by the dealer, unplug it.

Easy to do, easy to get to, I've been running it for 2 years with zero issues.

Just reduce the amount over the speed limit that the truck is run.

One was already installed on my Tuscany ZRX edition . It seems to work perfectly.

I know this doesn’t solve the problem, but when I run Waze (probably all map apps), my actual speed is displayed.  With Apple Play and Waze, it shows my speed right on the infotainment screen.  Seems like you could use that.  Also seems like after awhile of using it, you’d get a feel for the difference between your speedometer and your actual speed and just be able to do the conversion in your head on the fly.

I just figured out the CarPlay ...... for some reason , I had it off on my phone . 
Today using waze , my speed was right on between truck and waze .

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      Howdy folks,   Recently I pulled a heated steering wheel and clock spring out of a 2015 Sierra All Terrain (part numbers coming soon - will have to disassemble), and just installed it on my 2016 Sierra WT (as base model as it gets).   On install, I noticed that I’m missing the connector often tucked behind the dash for the heating element.     No problem… or so I thought.   I used an “Add-A-Fuse” at my heated steering wheel fuse location, which has voltage, but no wires. I ran it to the positive of the heated steering wheel (Violet/White), and took black to ground.   Hooked up the battery, turned the truck on - no heated steering wheel. No button backlights. Was pleased to see that my cruise control was working though.   Read a post suggesting reversing polarity, so I gave it a shot. Violet and White to ground, Black to power.    Aha! Heat! But I seemingly can’t turn it off AND still no backlights on any of the buttons.    Checked all fuses, everything is still in good order. I’m stumped.   Does anyone have any insight? If so, please share!

      Brake Pad Warning Message

      I'm about 1800 miles into my last oil change, and yesterday a message appeared saying oil life was at 77%. Not sure why it popped up but I think all of these electronics could be susceptible to solar flares or somesuch. I change my oil right at 3K each time, and that was the first time in 10870 miles that message came up. Strange thing is that it showed on the screen at all since I don't drive with that sort of info displayed on the DIC.

      Checked the pads today and there's plenty of meat on them. If the message keeps coming up, I'll just answer YES that the pads were replaced and wait for the squeal.
