Best Place to Order an Unlocked PCM

4108 Views 17 Replies 10 Participants Last post by  TheBlasterMaster
I'm wondering where is the best place to order a new unlocked PCM for my 2022?

If I were to install it and tuned it would I be able to go back without screwing up my warranty? Even if I have to wait for my warranty to run out I know things get more expensive with time so I still want one. I plan to keep this car forever.

exactly what dan said. yes, your warranty would be shot. if you got a 2nd pcm that was modified, do you really want to go through the hassle of installing and then removing the unit every time you went in to the dealer?

No. Once you tune it the BCM stores a code (P1400) that stays in memory and, should a significant drivetrain repair become necessary that P1400 code is going to be the reason Mopar denies your warranty claim. You can put things back to stock all you want but the code will still be there. Mopar will not approve any significant drivetrain repair without a full data dump and that's where they'll see it.

You cannot swap back and forth because the Vin# and exact mileage are required to get an unlocked PCM and that mileage changes as you drive and add miles to it. The catch is there is more than one computer on board that keeps track of the cars mileage and if that mileage does not match, the car is automatically red flagged.

There are many things you can do to your Scat without tossing your warranty out of the window on a brand new car, changing the PCM to tune it, is not one of them, think this over very carefully! Ry

Once you install a Unlocked PCM your Warranty is no longer good and no you cant just swap it back. Since 2018 the Dealers Data Log the Challengers
and the Cars BCM records data as well and it will show its been changed when they scan it. Id not risk a Warranty on a Brand New Ride.

As Per Steve White Motors ...

Anything that requires tuning will affect your warranty, basically cat back and cold air only, cosmetic mods etc are allowed.
Do not let any tuning pcm unlocking vendor tell you that their way can be hidden, it cannot.......
The manufacturer is now requiring dealers for any major components to induce a computer fault, which creates a scan report uploaded to them
Its good to know that I can't swap PCM's without them knowing. I actually thought you could but I guess not anymore. I won't void my warranty but I will tune it eventually when it's expired.

Yes, if otherwise all you had was, for example, a 93 tune and no physical modifications.

That way, you switch back to your OEM PCM when going to the dealer for routine maintenance. That way, (1) if they scan your car via OBDII port, it will (on the surface) read as factory, and (2) if they flash your unit without your knowledge, at least they won't be messing up your tune and/or brick your modified PCM.

It only takes a few minutes to switch PCMs, and well worth the effort to protect the nearly $1,000 spent on a cracked PCM and tune.

unless you bust the clip that is holding it, but like was posted by a couple of members, there are a couple of pcm's and it will note that the mileage doesn't match.
as for spending the money on the pcm, when i paid for mine and all the mods that i have done, my warranty went bye bye, and i knew that going into modding my car. that is main point, if you don't mind the warranty getting dropped, go for it.

Actually, it is not possible to simply switch back to stock ECM and go undetected. Once ECM is changed for any reason a P1400 code is locked into the BCM and cannot be unlocked by anyone, not even dodge but it's info can be read. ECM can go bad and a new one required. It will still throw a P1400 code but service records will substantial change and warranty remains intact. Unlocked ECM will be noted in P1400 code thrown by BCM even with stock ECM in place of unlocked one so warranty will be lost with either ECM in place.

Also Dodge is not the only company that did this all Ford, GM also have a variation of this type of PCM / BCM setup.
That is to reduce False Warranty Claims or those caused by Modding.
Fellow I know owns a Scat Pack that developed the dreaded Hemi tick at 43K miles. The dealer replaced the cam and lifters under warranty. But did not check the bearings for damage from metals. Two thousand miles later the engine developed a rod knock and the engine sized up. Warranty's are a good thing to have. Wanna go faster ? Buy a Hellcat is Dodges answer to that question, POS !

Never claimed you'd go undetected switching ECMs. However, I do believe pre-2018 6.4L did not register a code in the BCM when the PCM's were switched.

Regardless, my suggestion for switching PCMs (a/k/a ECM) wasn't to pull one over on the dealer, but rather to protect the investment in the cracked PCM and the tune, by eliminating the chance the dealer flashes the PCM unbeknownst to the car owner. A dealer flashing a cracked PCM is a surefire way to brick it.

Correct in that 2018 was the first year for revised BCM. Misunderstood your reasoning. One way for guaranteed protection for sure. Thanks for the clarification.
HP tuners
I have a 17 T/A and waited until the day it was out of warranty and added headers, cam, and of course, unlocked my PCM ($200.00) and ran a dyno.
