  1. I am sure this does disable bunch of features too, but I am wondering if there is a better way than leaving something plugged in. Maybe wire of the ground to something will make it think something is connected.
  2. It will "work" with lots of programming involved according to the community developer using the comma's system to interface with GM's control modules, it is out of reach for anyone that does not have the ability to modify and program ECM or any other OEM modules. I am following the community group for GM, it is doable with vehicles that has only Lane Keep Assist, the openpilot system will take care of the distance and keeping the vehicle in the center of the lane. Having Lane Keep Assist ensures the vehicle has the digital means to be interfaced for steering. I have a 2020 AT4, Adaptive Cruise Control can be turned off, but it actually works really well. I do want to point out, I had my old truck's snow tires on when I first got the 2020 AT4, the Adaptive Cruise Control was acting strange, feels as if it is a little slow to make changes to speed or apply brake. After I changed to 33.5 inch tires, Adaptive Cruise works very well. The vehicle has the ability to stay in the center of the lane, but GM has limit the amount of steering assist it will provide.
  3. I use it like this, keep the load on the stop itself from collapsing
  4. I am following this to see who has behind the grille option, active shutter is nice but the system blocks any aftermarket solutions
  5. Is it a 7 ping you have plugged in for it to detect? I am not sure why this is not enabled by default.
  6. AMP Power Running Boards, the only ones I have used so far that is low enough you dont end up kicking rocker panel's paint all the time.
  7. I am short, ~170 cm (5'8"???). Moved from a 2014 All-Terrain with 2.25" block and bigger block in the rear with AMP running boards and 33's to 2020 AT4 also with AMP running boards but now running 33.5's. It is bigger, bigger than a slight lifted old body style, but I comfortably get in and out. My house is build in 1970, fits the truck fine with the antenna hitting the top. I have removed the antenna and ran a wire to the passenger pillar seam meeting the windshield instead. Funny how old houses garages are bigger, trucks were smaller, new houses garages are smaller, new trucks are bigger...... go figure
  8. Thank you, I will get the MX4 with this info!
  9. I hope someone has installed Bakflip MX4 or similar covers that is tri fold and leans to the cab where it allows the new camera mirrors continue to function without it being covered. If anyone has a tri fold tonneau cover installed and can verify the Camera Mirror does not get blocked, please let me know. If there is any slight obstruction in the image on the camera, I am ok with that. Anyone with any photos to show it not blocking the camera would also help! Thanks!
  10. 6 and the 8 speeds by GM is trash, hit and miss on each vehicle for some reason. I have the 2020 AT4 with 5.3, smooth shift regardless cold warm or switching out of N,P or D compared to my 6 speed 5.3 2014. I worked for a GM dealership as a service writer, lots people complained about the 6 speeds all the time, same thing when 8 came out, no complaints so far with 10 speed customers so far. I am glad Ford and GM worked together for this transmission, really is worth it.
  11. Just read your thread dealing with rpm flucations thought to be a transmission or TC issue.  Wondering what your fix was. Tried clicking the link you shared for the fix but it wouldnt load.

      Yes, ended up to be a cylinder constantly misfiring ending up tripping "P050D" on the odd cases that allowed the dealer to recognize there is a issue. 


      Need to hook up a real time monitor to see the misfires happens when the fluctuation happening, if it is not severe enough, I dont think any code will trip. Took a long time for the P050D to show.


      I was lucky that I have the issue documented and repairs attempted under 60,000 KMS base warranty, I got my GMPP deductible back.


      Keep me posted, I work at a dealer now in Edmonton, email me is easier

  12. Try to get it written off if that is the case. We did a frame swap on a 2016 2500, it was a pain in the ...., Airbags and all the wiring had to be redone. Most of the stuff for powertrain is mounted on the frame, all that has to be transferred after they lift the cabin
  13. You have to call onstar to have it added. i remember someone had the factory remote start onstalled after the fact and had onstar to add it to the profile
  14. Get them to check misfires now! And try leaving the truck with them overnight and have them test the truck at cold. They are going to see misfires, looks like you have more than one cylinder misfiring. They need to replace the injectors as per cylinder misfiring if they see P050D but it will take a while before that code appears How many KM on your truck when this started?
  15. I am in edmonton, I work for lakewood chev now in service, gonna be able to get the diamond kote tdon at a discounted price while I am at work. I have sandblasted the most visible area like right at the rim of the coilover mount, sprayed it with matte finishing rust paint from princess auto. To be honest, looks brand new there. I did blast more area, it is pretty much all the way around the outer edge of he frame. Took me two days after work. Truck will be on a hoist and they will spray diamond kote underbody coating which also adds sound proofing to road noise
