We put 35" Maxxis tires with 22" Fuel wheels on my 2022 Silverado LT with the new, refreshed dash. This required a 3" front and 1" back level. We started having issues with the cameras calibrating after about 6 months. Basically, the system can't calibrate the distance properly so it gives you an hourglass in the upper left hand corner of the screen showing the system is "working", a nice throwback to the microsoft busy icon . This leaves you with no grid lines for parking and no trailer assist. The dealership replaced the front camera and recalibrated the cameras. After working for two weeks, the issues started up again. 

 

Email from GM engineer to dealership stated that the software only allows for 2" of extra distance over stock ride height for the cameras to calibrate so there was nothing we could do and would be left with a dysfunctional system.

 

There are new Black Widow package trucks out there with a 6" lift that have zero camera issues. The reason why is that Black Widow had to develop their own software in coordination with GM to overcome this seemingly simple issue. GM knows their trucks are going to be lifted. They even offer the 2" lift from the factory on some of the packages. So why not just include this extra distance to compensate for this in the software instead of pissing off people who paid for and really just want their truck to function properly. Black Widow won't sell the software and GM won't offer it as a patch. So, in order for your Silverado/Sierra to function properly, you need the $20k black widow package...

 

A bigger issue I see is the safety of the vehicle. Should I trust the adaptive cruise and lane keep assist to work properly if the software doesn't even know how to calculate the distance for some parking grid lines?

 

Does anyone know of software out there that has been developed by third parties to overcome the camera calibration issue?

Unless you can find a company that knows how to do it your SOL. GM isn't going to spend the man hours and costs with doing calibrations for every possible combination of lifts and levels.

There isn't an infinite number of combinations required, it is a static distance from the ground to the cameras. It is an algorithm to calculate the distance and compensate for additional height.

GM won't be of any help here as they don't offer calibrations that comply with aftermarket modifications.  None of the issues you are having should even be covered under warranty either because of the aftermarket modifications and the dealer should have stopped right then and there when you pulled up.  Mods that are not GM that cause issue are grounds for warranty block.    

 

The only compliant lift that GM can help with is the factory Trail Boss lift kit as it has authorizations for camera calibrations.  

 

The other problem you are facing is the tire diameter.  The assist systems are dependent on the proper tire size based on the calibrations in the systems.  GM only has calibrations for factory tire sizes and the new trucks on GM Global B are very sensitive to this.  

 

TLDR:  Remove the lift.  Problem solved.

It's more complicated than that but you are kind of right.

It's really only X,Y,Z, roll, pitch, yaw that can be tweaked and likely it's just the Z to adjust on some of the cameras (not equally but close) but GM and their software will not let anyone touch these directly, like ever.

Actually I'll be damned, someone actually offers a service to reprogram your VPM.

I imagine they could tweak these settings.

Not cheap but probably not many options for this niche.

We'll take a look at that. This is the refreshed dash with the new layout so it's hard to find anyone that is doing any software mods. Hoping to find a fix so we can get everything working as it should.

Modifications on current model trucks have way more factors to consider than before. 

While I understand the issue I cant see how its GM's problem when something is modified beyond their design parameters ?   Its not 1978 anymore.  GM is hypersensitive to modifications causing warranty claims, dont expect that to change.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Progress... sort of.   Intake is disassembled, spider is out, fuel lines removed. Used a torch on the stripped screw with the lower intake off, much easier when I've got the intake sitting on my workbench, I made it talk. Walked right out with a pair of vice grips once it was nice and toasty hot.   New parts are piling up on my service cart waiting to be installed. Distributor, temperature sensor, new gaskets, fuel line kit, themostat, water neck.   My new pickle is I don't want to spend $600 on a replacement spider. I'm not sure IT is bad. I'm probably splitting hairs. Or it's $300 to send mine away and another 3 weeks of the truck just sitting. I have half a mind to assemble everything with the old spider to see if I can get away with just replacing the fuel pressure regulator to be safe. The obvious issue was the gushing high pressure fuel line which will be replaced. Getting to the spider really isn't that hard, and now I know what I'm doing , swapping it would be a breeze should it absolutely need one. Stupid, or smart?   The part that gives me pause is replacing the distributor. Well, it's already out. And I didn't mark it, whoopsie! Engine was at TDC when I removed it, I know that, so upon correct reinstall the metal tip on the rotor should point to the TDC mark on the distributor because that's where it was pointing on the old distributor. Worst case I'm a tooth off and have to re-stab it.   But then, what? I assume the truck will start. It doesn't appear the timing can be set. Here's the problem: These distributors can't be rotated but a degree or two, by design. What I read is Cam ****** needs to be -2 to +2 degrees, ideally at 0 (and checked/set above 1000 rpm). There should be enough wiggle to get that properly set, but checking the reported value is another potential issue. My Actron 9185 scanner says it supports enhanced GM PIDs and Cam ****** is one of them but it's unclear that I'll be able to correctly see it over OBD 1.5. I can see why people end up junking these things with life left in them. They're an absolute nightmare with tweener-year diagnostics/electronics and unobtanium parts.   Fingers crossed it starts and idles nicely. There can be hope, right? I'ma buy a lottery ticket the same day just in case.   Next steps..DO IT. I have not installed an intake before so I've been reading and watching a lot. Some say NO RTV except on china walls, some say DO RTV on water ports but not fuel/air intake. 1/4 or 3/8 bead on China walls? I think my strategy will be, obviously, RTV china walls with overlap on the gasket corners. Chapstick-style RTV the water ports. Leave intake ports dry. The only set of intake gaskets I could find locally are Edelbrock performance gaskets (uh...for an asthmatic 190hp V6? LOL) so we'll see how they do.   #NoToolLeftBehind. It took an hour, but my recovery mission for my deep 10mm socket was successful. It had rolled down the bellhousing and wedged itself between what I think are the fuel lines? I couldn't see it at all, but with a junk antenna I had laying around, I blindly went poking/sweeping for it, heard it clink, raised the truck, and caught a sliver glimpse of chrome with a flashlight way up there in Narnia. I had pushed it farther along the lines holding it captive, but within access of severely improvised tools, poking and cursing at it to finally knock it free to where I could get a fingertip on it to bring it home.    Not much to see.

      2027 GMC Sierra: Official Discussion

      By KARNUT · Posted

      It wouldn’t have happened if the government hadn’t mandated outrageous fuel mileage standards. It does very little for the consumer. It adds cost. Back during Covid there was a chip shortage. They gave a rebate for your truck if it didn’t have the chip to turn on cylinder deactivation. It was 50$ because at best you may see 1/2 a mile increase per gallon. Splitting hairs each fuel mileage trick wasn’t mandated. The government doesn’t do the engineering work and say use this until it’s already in use and they like it. The fuel mileage was mandated. And those add ons the results. There’s a mandate and they are the results.
