ECM reprogram/DFM delete?

[JD319]

Looking for those who have done a full DFM delete, IE: New cam and lifters.
where did you get you ECM reprogramed? how much did it cost?

I'm following myself. Would like to know also

According to Donslife on YouTube, he states that putting transition in manual mode, one less than maximum speed, ie: L9 for 10 speed, L7 for 8 speed, M5 for 6 speed - will disable DFM/AFM. He owns/drives a Silverado and says that a viewer has validated his claim with an ecm reader. If true, this is an easy no cost way to disable AFM/DFM. This is just FWIW, so please don’t shoot and gut the messenger.

Yes, this does work...but the question here is not how to temporarily turn off DFM, as that doesn't solve anything. What the OP and many others are looking for is a path to actually cure the DFM issue - i.e. remove the offending lifters. To do that we need a way to permanently remove all DFM functionality from the ECM, and as of yet no one on this site has confirmed that that can actually be done.

OP - I have yet to find any confirmation that this has successfully been done anywhere (DFM specifically, I know AFM deletes have been done), and knowing how difficult any kind of programming is on the T1 and newer trucks, i'm not confident that it's actually possible. But if it is, i'd love to know too.

I did the the DFM delete, but I just use the DFM fooler in the OBD port for now till I get more info and who can do it locally.

Just to update - I now have confirmation that it CAN be done. Several guys on the HP Tuners forums have given step-by-step instructions for how to disable DFM in the ECM. I have not however contacted any "for hire" tuners about it so I can't say who is willing to do it. With those instructions available, I will just purchase an HPT license for my VIN and do it myself.

I've done a DFM delete on my 2020. I started a thread on a recent spare engine where I'm doing the mechanical side of the delete. I'll make another thread in my spare time on how to do the tuning side via hp tuners.

You will have to send your ecm to hp tuners to have it unlocked. You'll need to purchase an hp tuners MPVI3 and then pay licensing costs. For a global A 2019-22, that's about $1000. For a 23+ Global B its a bit more, but the unlock and licensing is currently on sale.

Any HPTuners vendor that tunes (writes or sells others tune) will do the delete...it is not an emissions required part from what I understand. It was meant to meet the mileage requirements Obama set forth...
