[@alondraz2836]

Who did you get the tune from?

[@neil9503]

I have a 2017 ltz z71, and she is getting a lot of love soon! Thank u, stud. u did these videos like I would do! I always get pissed at the time people spend explaining shit that is not relevant to the situation at hand, U didn't do that great job... I was that guy in Georgia who used to build 3" & 5" down pipes for Grand Nationals for So. East Turbo, so I know how difficult it can be to create a perfect picture out of your mind for someone else to understand with basic instructions.

[@bradycaroll2198]

You answered my prayers this is why I love your videos ❤

[@MuscleVsTuner]

Man this video was so helpful you have no idea. Great job brotha!

[@nombr]

Good video man, I don’t have a l5p but always enjoy your diys. I really do like the cruise/tach for sotf. I used to run a switch for my 6.7 psd but got rid of it because i thought it was causing issues (also never took it out of 5 lol)

[@darkirondiesel]

Haha ya the temptation is real. I’m just running a single 75hp tune on my Cummins for that exact reason.

[@briang7870]

​@darkirondiesel I'm running a 75hp ccs tune as well and get really good mileage on my ho but vgt position doesn't close all the way during cold weather warm up.

can i flash the stock read file back into truck or do i need a delete file? i just want to remove the factory speed limiter for now

[@philipneville3172]

Awesome video man

[@thesebootsride]

I’ve had a hp tune for about 6 months now in my 2020 l5p. Is there anyway to get the idle changed. Mine starts are 600rpm and after about 30 seconds goes up to 900rpm and will not change unless I go into gear. Once back in park it goes back to 900. Pretty frustrating for such a expensive tune

[@zachary2417]

What’s your thoughts on the gmc ? Should do a compare video on your 5th gen and this l5p pros and cons etc

[@darkirondiesel]

I’ve always liked duramax engines. They are fast and I think they are reliable. But now a days they are all nice and reliable for the most part. So if I were truck shipping I’d just go drive them all and pick the one you like best. My next truck will either be a duramax or powerstroke just to switch things up a bit.

[@EliasStonehocker]

Can you drive the truck after tuning but before removing parts I would like to do at the house so I have WiFi but my shop is a couple miles down the road would that hurt? I have a 2018 3500 L5P

[@daltonbuck4502]

Awsome video, thank you so much man! Very helpful

[@DanielGomez-mm5no]

Why does my truck not have the same fuse box it’s a 2019 Silverado. It has a completely different fuse box. I don’t know why.

[@cooperlauck186]

To do the" resync interface" @ 7:25 , do i have to have the mpvi hooked into the truck? I got it all hooked up to my computer, but the program isnt picking it up. I dont have the truck yet, but was wanting to get everything ready that i can before hand

[@bryanspanjer3213]

Thank you so much. Well done

[@joeb.8625]

If anyone could answer this question please do- I’m already unlocked and I have a towing tune. I would like to get sotf . Since my ecm is already unlocked do I still need to get 8 credits? I would also like to get trans tune I have a 2022 Duramax dually

[@fireflyraven2760]

Um quick question say you are doing this to more rhen one vehicle.do you have to reinstall this update in oreder to continue the proccess or is it just it is now o .the computer so no need

[@westcoastwaterman]

I have a truck that already was deleted with a HP computer but the computer showed the wrong vin and year and all of a sudden acted like it wasnt deleted so I replaced it with a new HP computer and now I have to delete the new computer, but emissions are already off. I bought the vcm with credits.

[@lilcradio]

Great content love it bro. Did that check engine light ever come back after driving it around though?

[@keithjeffreys4244]

So I’m looking at doing a DPF/DEF Delete. Can you do a video or comment here what the different types of delete there is. Is it required to remove the EGR? Or can we do just this tune and the exhaust? Or is the tune all you really need?

[@matthewenderle8880]

You mentioned the level of the DEF is important. How does one see the actual level? My 2017 just says "Good".

[@frederickcarrozza1408]

so you tuned first before the delete, when you deleted it did you need to upload a different tune for being no emissions? how is your truck not throwing codes for the emissions is it the can bus plugs?

[@darkirondiesel]

The tune that comes with it I did on the other video is an “emissions off” tune which turns off the emission system and blocks any codes from popping up.

[@kiingmccoy6383]

Does hp tuners send you a tune once you do the unlock and does the tune automatically have the regen cycle off or is that different?

[@darkirondiesel]

If you are deleting your truck this is the kit you need shrsl.com/4ke0x it comes with everything I used in this video along with tunes that disable the emission system.

[@slidewide1999]

Originally the L5P you had to do an ecm swap right, similar to ‘22 and later Cummins trucks? Do you think this unlocking procedure will be available for the Cummins?

[@darkirondiesel]

Great question, and to be completely honest, I don’t know. I’ve been hearing tuning companies saying their close to figuring it out, but I’ve been hearing that for over a year now. It took them quite a few years to figure it out for the L5P so hopefully one day they figure out the Cummins, but I wouldn’t hold your breath.

[@panic4949]

Was going to ask the same question. Really don’t want to pay $4000 for an ECM and Unlock.

[@aden6128]

It its 😏

[@tannerparrent8490]

What’s wrong with downloading latest stable version ?

[@EdGrizzo]

Any word on 2024 L5P delete?

[@JoseMedina-jt7ip]

What do you mean when you said Emissions on and off. Im doing a full delete on my 2017 DURAMAX. My service exhaust fluid light keeps blinking and the Engine light is on. Will the tune take care of all the emissions codes (the light that keeps blinking) or will I need to do a force regen or something to make the light go away before tuning?

[@darkirondiesel]

If you get the kit I used shrsl.com/4ajh9 then it should remove the emission light but it might take a couple tune revisions to get rid of it. That’s why you always tune first and confirm the tune was successful before removing any parts from the truck.

[@GregMyers-WWK]

Mine don’t have the read ECM button? On the VCM

[@warrenaparicio5707]

How much is it to delete one of these new L5P's in CAD? Did they figure out how to unlock these ECMS?

[@andresauve4878]

After tuning I was getting code P0700 and others that wouldn’t clear. Luckily disconnecting the battery reconnecting and checking no codes appeared.

[@BigBlockSpence]

Does the unlock Box come with the delete kit? I have mpvi3 but there’s no ‘unlock box’ that came with that.

[@darkirondiesel]

Yes the kit I linked comes with the mpvi3 tuner and the e41 upgrade kit (unlock box)

[@Anonymous-wu8mg]

If you wanted to do transmission tuning would you just enable the TCM option where you said not to when selecting ECM? Only thing holding me back is I wanna do it all at once

[@darkirondiesel]

I believe you need an unlocked tcm for transmission tuning which you could contact gdp and get that as well

[@hauto383]

I know they were having some major issues with the SOTF on the L5P. Have they got the kinks sorted out with that now and its not longer bricking ecms?

[@darkirondiesel]

I’ve never heard of guys bricking their ecms on an L5P so yes I’d say it’s sorted out.

[@lylenelson7446]

I'm running motor ops sotf running. I usually stay in tune 1 which is the 85horse tune and might occasionally use tune 2 or even 3 for a smile. Never use tune 4 or 5 because I don't have a built transmission. I've had zero issues just pure joy and peace of mind

I have a question. Why did you tune with HP Tuners? Dosent the kit from thedieseldudes comes with the tune plus all the parts you need?

[@darkirondiesel]

All this was from the diesel dudes.

[@tandr06]

Here's a burning question from me with a brief background. For the 2nd time in 6 months, it appears my DEF tank needs to be replaced due to a faulty sensor. I currently have the "Service Emission System" code up with the limp mode mileage countdown starting. Do I need to have the dealership resolve this, or will the tuning process clear this out? Ordering this delete kit in the next week or so, can't wait!!

[@shawnsaenz]

So..if i buy the "HP Tuner kit" i have to buy tune credits? Are tune credits from HP Tuner as well or from a seperate "Tuner"?

[@1Bagged17]

I used to have a 2018 l5p and deleted it myself and I traded it for a newer 2021 l5p can I reuse my e41 unlock device on this one? Or do I need to contact a tuner?

[@shawnsaenz]

What about the DEF tank? Can it be removed? Or does it have to stay ?

[@darkirondiesel]

You can remove it

[@jerrt22]

I bought my kit from spelab, you need to buy your can is plug kit separately which they sell and you’ll have to buy the unlock tool from hp it’s like $350 I believe, It says it suppose to come with credits but I’ll find out here in a while I’m working on download all software now

[@clark8534]

Dumb question but if you had to revert and put the emissions stuff back on....can you upload the stock tune back to it and put everything back in place?

[@darkirondiesel]

Not a dumb question, but yes you totally could do that.

[@darkirondiesel]

I definitely recommend adding that plug kit if you’re thinking you may have to do that in the future, just because if you don’t all your open sensor plugs will corrode from moisture

[@dustinshepard3166]

So these tunes will work for deleting the truck right? Because I wanna do a full delete and also these tunes are directly for HP tuners?

[@darkirondiesel]

If you get this kit shrsl.com/4ke0x it comes with the mpvi3 tuner and e41 unlock kit AND it comes with the delete tunes. It’s everything you need to delete the truck.

I just finished delete and tuned my truck, this also happened to me without any codes prior to install. I have a 2018 Chevy. I am currently contacting Diesel dudes and HP tuners and waiting for response. Did you have any luck solving the issue ?

[@Noslackk]

So I have a 23 L5P and I had previously installed the Edge Cts3 Evolution that had the unlock for TCM and ECM. Being that I had already unlocked the Modules would that cause any conflict with the HP tuner software when I want to T&D in a few months and if not would I still be able to use my CTS3 as just a monitor since it has the Evolution tuning software installed in it? Thanks!

You can get emission compliant tuning but you’ll still use def and your emission system will function normally. If you are wanting to delete the truck you have to tune it then remove the exhaust at the very least.

[@dylanbenner3446]

After upgrading the ECM and uploading the tunes, is it okay to still drive before doing the delete?

[@darkirondiesel]

For a little bit ya but they don’t recommend you drive more then 200 miles like that. It can damage your engine. And keep it on the lowest setting.

[@CallMeTheRealE]

What if the reason I’m deleting is because my DPF is having an issue

[@darkirondiesel]

Then make sure the tune works and you don’t have any lights before removing any of the parts. You might have to try a couple tune files to reset the emission light/message then tune the delete tune on. Just don’t physically delete the truck until you’re 100% sure the tune worked. I’d unplug everything on the emission system first and make sure the truck starts, runs and drives with no engine lights or messages, then do the delete.

I can’t be the only guy wondering if you can just tune the egr and def systems from working? Why does the egr system have to be removed? Imagine the valve would just remain closed. leave everything in tact but remove entire dpf system. is there really no way of accomplishing this with a tuner even now? Hypothetically speaking

[@darkirondiesel]

The egr can be left on the truck, you just need to unplug it. The exhaust NEEDS to be changed though. If you wanted to keep a stock look you could drop the factory exhaust, take it apart and punch out all the internal filters then bolt it back up under the truck. The main thing is getting the restriction out of there.

Left it alone on this truck. It’s a completely separate module so if you want you can buy TCM tunes from a company of your choice and use the mpvi3 to install them. I think you need an unlocked TCM though.

[@darkirondiesel]

If you have the mpvi3 device that programmed your truck the first time you shouldn’t need to buy credits. If you are buying a new mpvi3 device and using that to tune the truck then yes I believe you would need credits. The credits link the vin of the truck to the mpvi3 device. So if you use a new mpvi3 device you have to buy credits again. At least that’s my understanding of it.

@ my tuner did it so it was his so I don’t have one, but do I need all 8 credits since the ecm is unlocked or that doesn’t matter it’s 8 regardless
