Hello, 

 

I have a 21 with the 3.0 Duramax and so far am very happy with it other than the occasional crank no start that others have experienced. I've found very little info on if they're able to be def deleted and tuned or if anyone has done so with luck? I'm only at ~16500 miles and wouldn't want to do anything prior to my warranty being expired but assuming it's a reliable motor and be a long term vehicle, I would consider it with the hopes it would improve efficiency, performance, and sound better. 

 

I'm new to the diesel world and know very little about this so more of a curiosity question than anything. Any info or insight is much appreciated.

Take it for the programming update to get the crank timeout / no start corrected.

There are still no real tuning solutions for these engines and since this is the case, no way to do a def delete yet. You've got a long way to go before your warranty is up!

I was under the impression I had a 3 year/36K bumper to bumper warranty and that the 5 year/60K was optional. Am I wrong or is there a specific powertrain warranty I'm not aware of? If so great, but on Chevy's website I only see this and looks like it only applies to 2020 models.

If you’re looking for something that will change the way your truck responds I would look into getting a banks pedal

monster. I just installed one on my 3.0 and I really enjoy the results. Install was about 10 minutes there are plenty of YouTube videos on it. This module is not a tuner that gives you more performance but it does change the throttle response and you can adjust it to your specs. I found that the Duramax lacks a bit on instant power that I would like and this module takes care of that. Banks also claims the module doesn’t leave a foot print so you can disconnect it when you have to take a trip to the dealer for any repairs. Banks is also developing an actual tuner for our 3.0’s and you will be able to stack both mods without any problems. Hope this helps GL

This does not correct the issue. I took mine in this past Tuesday (1/25/22) for PIP5823B Intermittent Extended Crank No Start. Then 4 days later it did it again. Those of you have have had the shim installed, did that correct the issue? Or has anyone else had this update performed and still had the issue?

Going by what my dealer told me, they have to check the integrity of the wiring harness and would need to keep the truck for 2 days to accomplish this task. I don't know how factual this is, but that is what I was told by the service advisor. I will be trading my truck in for a refreshed 22 diesel, so I will let them accomplish that task once I receive my new truck.

They don't have to spend two days checking the harness before applying the update. 

(maybe I misunderstood what you're telling us)

 

Mine was in for something else today and the did the update while it was there.

Less than an hour total. 

 

Perhaps extended diagnosis if it it does crank/no-start after the update?  

If one is still doing and has already had the update, then that could require more diagnostics. 

 

Most have reported programming update corrected the problem. 

 

 

Otoh, it wouldn't be the first time a service adviser was wrong about what the techs do / need to do.

I order a 3.0 duramax in 2019 and i was one of the first to get my hands on and i drive 100k a year no problem, right now i have 156k and had no issue whats so ever the whole time, except now its in the shop and waiting for timing chain and belt parts, crank chain was streatched about an inch" dealer says its from using old oil, who in the crazy world would use old oil? I ask the dealer, i told them to pull up my history purchases and look for oil change records, all done by the same dealer, BANG back fire no longer was the issue of old oil, so warrenty is fixing the whole nine yards,

Any vehicle I purchased new goes to the dealership for maintenance. They can’t pull out the excuse book it’s all on the record. You don’t have to do everything they try to up sell, just get familiar with the manual. Some people say they have a kid doing oil changes. Well he does more oil changes in one week than most people do in a lifetime. I’ve been using the same couple of dealerships for 30 years. Sometimes spending a few more dollars, it’s paid off in the long run.

      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.
