I had to go twice because the first visit, the dealer did TSB 21-NA-228 at my direction but the programming for that didn't work in my truck. When I went yesterday, they did 21-NA-056 and the programming for that one did work. If I would have known about 056 the first time, I wouldn't have had to go twice.

So they charged you for the second one, even though their TSB didn't correct the issue? That's kinda shitty.

Found this TSB released last month stating there is a factory offered "fix" for those who want to do away with the idle time-out.   #21-NA-228: Full Size Trucks Idle Time-out Disable - (Oct

Interesting. I didn't catch that "feature" in the owners manual, but there it is, "Extended Parking" with the timeouts listed. Good to know. I'm fairly certain I hate RKE/rfid fob stuff now. Gimme a d

For what it's worth, you can disable this with WAMS as well... and have tons of other goodies to boot

Isnt it like 800 bucks? I couldn't tell what all was needed and how long the truck would be down for.

Price has gone up a bit due to chip shortages but not quite 800.  300 for tune and 295 for device $595).  Truck will not be down at all though.  You select the options you want on their web portal and then plug the device into power.  It downloads the new update and then you flash it to the truck.  Takes maybe 10 minutes total.

 

Some other things that I use.....  

 

  • Auto close/open for sunroof (no need to hold the button)
  • Enable Fogs and DRL for approach lighting at night (no blinding headlights)
  • Removed door chime
  • Set one touch lane change interval to 6 while towing and 5 while not (3 is default)
  • Emergency strobes/Wigwags
  • Windows UP with keyfob

Thanks. I read it that I thought I had to send them the BCM. You don't have any screenshots of the changes that can be made, do you?

You do not need to send the BCM in.  You just make the changes in the portal as shown-->Plug the device into power and let it connect to your WiFi and download the tune-->Plug it into the truck and start the flash process.

 

Here, you can see I adjusted the Approach Lighting (when you click the keyfob at night).  The DRL, Park Lamps, Reverse, and Turn signals light up.  No eye burning laser headlights :)

 

@GTPprix is the original owner.  Good people

So after my 3rd or 4th time with customer service still no luck getting the idle time out shut off.  The have never heard of a TSB before.  There tech department has no idea what I'm talking about.  Tried to explain that I work as a firefighter and I have chevy's on my department with that feature turned off and they still have no idea how.  I'm ready to sell this damn truck.

So I’m looking at getting the idle timer disabled on my truck as well but my service department told me that this TSB did not work on the 2022 limited Sierra 1500 duramax. Is there a different TSB for the 2022 limited or is it not available at all. Thanks for your help.

Getting the same thing from my dealer on my 22 limited. The TSBs referenced in this thread stop at the 21 model year.

I believe 22 and up has a different programming architecture that is basically locked tight from the factory now.  I am not sure anybody has cracked it yet.

So it appears WAMS is out of the programming business. Is there any other options for this? To anyones knowledge?

      BAK MX4 EZ-Lift Install and Review

      By parthery · Posted

      I've been eyeing an upgrade to my tonneau cover for a bit now.  Intrigued by the BAK MX4 EZ-Lift with the torsion spring and went for the upgrade.  Thoughts and musings during unpacking, install and a few days of usage.   Once my order went into Realtruck, it took about 4 days to ship.  Unfortunately, FedEx Ground destroyed the box and contents and it was unusable upon receipt.  To Realtruck's credit, one email with pictures and an RMA was sent to me to send the first one back, and another unit was shipped out.  It arrived 3 days later, unscathed.   I opened the box and it looked like every other BAK MX4.   Biggest differences are the rails and retaining clamps, and of course the spring attached to the cover itself.     NOTE - if you are upgrading from a MX4 to the EZ-Lift, you will have to replace the rails.  The EZ-Lift rails have a notch cut in them to allow the new style retaining clamps to fit properly.  The new retaining clamps also have 2 knobs/carriage bolts and there are two tracks underneath the front panel. The strap clips are mildly different (more like the Undercover Flex clamps) in that the screws go in from the underside.  Personally I prefer these over the BAK clamps that use the nutserts that are a nuisance to install.  The remainder of the parts in the box (drain tubes, rail clamps, and bumper pads) are standard issue BAK.     I did not replace my front bed seal at the time because it seemed to be in decent shape.   BAK recommends shims on the GM trucks unless you place the clamps on the flanges about 1/3 of the way in from both the front and rear of the bed.  I shimmed the front and the middle, and initially placed the clamps equidistant.  This also turned out to be a mistake, because when I set the cover in place, the new style retaining clamps wouldn't clear the front clamp.   New style clamp inserted in the track:     And the issue which occurred because the front rail clamp was too far forward:     Once I removed the shim from the front of the bed, and slid the clamp back to the front flange, everything cleared fine.     The cover set on the rails without issue and I installed the strap clamps.  After I completed my adjustments, I pulled the pin to activate the torsion spring.  Mistake #3 on my part.  PULL THE PIN AS THE VERY VERY VERY LAST STEP!  The reason is, once you pull the pin, the torsion spring is activated.  If you have to loosen the front clamps and adjust the cover, the front panel will - by virtue of the spring, refuse to lay down.  The only way to get it to lay down so you can reinstall and tighten the clamps is to fully open the panel against the back of the cab, which will then allow the front panel of the cover to lay down and be tightened.  Not a big deal unless you haven't installed the foam pads yet (typically the last step) because minus the foam pads, you will need to place something between the frame of the cover and the back window so it doesn't get scratched.  The next time I install one I will install the foam pads before I pull the pin and activate the spring.   After using it for a few days:   The spring assist is great.  You literally can open it with one hand.  My shoulders aren't getting any younger and this was part of my motivation to swap out. The second panel latches and unlatches itself as you open and close the cover.  Neat in concept, however it took me a minute to get used to closing the cover and not hearing the "latching" sound that would tell me it was locked in place. The paddle handles are a huge upgrade and I wouldn't be surprised to see them become the standard across the Realtruck line.  They effectively eliminate the concern that a thief could coat hanger the cover open and get to the contents in the bed. I'm not sure why the very front panel on my cover has a different finish from the other 3 panels.  I have a request into Realtruck to find out if mine was not manufactured properly or if it was by design.   All in all I'm pleased.  Same level of protection, looks good, keeps stuff mostly dry (they all leak around the tailgate) and easy to install.
