How To Tune And Unlock Your L5P ECM With HP Tuners

This goes over the procedure to tune and unlock the ecm on your 2017-2023 L5P Duramax with HP Tuners.

***Underneath the VCM Suite BETA download you will see "Application Prerequisites: Net Desktop Runtime Windows x64" click that link and download it first, then download the VCM Suite BETA.

If you need credits you can simply purchase them online, just create an account with HP Tuners, add your mpvi3 device, then purchase credits for it. Once credits have been purchased just go into the vcm suite editor and select “resync interface” and they should be automatically applied to your device. See video below:

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)

Gonna do mine once i get my parts in a bit here, this should help out quite a bit.thanks a lot

[NorthernHDrider]

Do happen to have an instructional video for the transmission tuning process? Thank you!

[joenowe]

[guillermotaboada]

The video was perfect man, thanks a lot 👍

[zachary]

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

[rsbreeze]

Duramax Tuner and PPEI are both saying they are working with HP Tuner on the ECM hack for the 24s. Until that happens, no go. I just messaged them August 25, 2024.

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?

[lilcradio]

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

[daltonbuck]

Awsome video, thank you so much man! Very helpful

[matthewenderle]

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

[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"?

[Ruffles]

How do you know if emissions on tuning? And emissions off tuning?
The tuning will tell you? Or the tuner company?
