How to install the new GM E41 ECM Upgrade Kit | HP Tuners

[@TireSmokin1]

For anyone who is new to the HP Tuning game. HP Tuners is a hardware company that allows the ECM (engine control module) to be modified from factory. They do not modify the tunes. You will have to contact a tuner and send them your stock tune to be modified prior to mechanical modifications. Such as larger 67mm turbo, larger injectors or any and all forms of delete. I recommend Duramaxtuner for the 150HP 5 way compliant tunes and then see if you feel the need for something else. Just my 2 cents.

Thank you for this comment, I want to delete my l5p but am new to this. I understand the process but do not understand how to acquire a tune file....credits? Where to load it? Etc. Any advice would be much appreciated thanks!

Will this also unlock the TCM on a 2021 L5P? I would like to be able to both.

[@patbramble8958]

Does this tuner allow for a gearing change for larger tires and retain the OEM cruise control? That is the functionality that I want to know.

Does this also help unlock the tcm for transmission tuning for the 6 speeds '17-'19

Can I write my stock tune off my ecm and still use my truck while I wait on custom tunes. 2020gmc 2500 4x4 6.6

Can you manually uncheck the ecm codes for emissions deleting

[@MrWeaponlord]

Any news for the GM e46 unlock cables?

[@moso240]

Is the upgrade module reusable? As a shop can we use the same module for multiple vehicles?

[@timevans3541]

Assuming you will have to purchase tunes(credits) first?

[@HPTuners]

Hey Tim! 👋 Yes, during step 5 of the upgrade process, users have to license the vehicle to their interface. The instructions are linked in the description if you want to check them out. Thanks for watching!

[@SinistaWs6]

Is there a link on the hardware I need to buy so I can tune my 2021 L5P?

Any answers?? I have the same question.

Yes, this is what allows for that. I’m getting my stuff this week for it. This is the first step before running “clean emissions”
