2010 5.7 PCM/ECU Swap

[Christian6090]

I have a 2010 Dodge Ram 1500 5.7 2wd. I need a new ecu/pcm. what year models are compatible with my truck so i can find the part at a salvage yard.

any information helps thanks!

You are most likely going to need to find one out of another 2010-11 2wd match the numbers up on the ECM its self you will have to reprogram it aswell its not plug and play. What is wrong with your current ECM they really dont fail on these trucks very rare unless you shorted it out or something.

the ECM does not send signal to the alternator to charge, I’ve sent it out to get fix but they said it was unrepairable. Thanks for the information, I’ll look at those years than

For a rebuilt reprogrammed PCM, call 1-800-225-5345 and give the VIN of your truck. close to 300D I remember.

Is it possible to swap a pcm from a same year and Drive train that has been tuned to go into my 2009 laramie ?
Also what steps are involved and what guidlines or rules are there when swapping a pcm from one truck to another ?

Just curious, but the guy you quoted, posted that answer, to someone else, a year and a half ago... His answer, that you didn't like, occured a year and a half before you asked the question? Or am I missing something?




Anyway, to answer your question, Yes, another PCM from the same year will swap right in, physically.

But, it needs the VIN and vehicle information programmed into the PCM or it won't work.

AlfaOBD has the option in the Engine Computer - Active Diagnostics tab, to program the VIN and to write the vehicle information to the PCM. I can't verify that it works though, as I have not actually done it myself.

Or, alternatively, aftermarket companies, like the one in that year and a half old post up above, can program it for you.

I have an unlocked pcm in my 2017 and a Diablo tuner. I bought a cheap pcm on ebay and sent them that for my pcm swap since mine was still working. I paid less than $100 for the pcm that I sent them. If you go that route you have to send them a working pcm. Otherwise they'll charge you a core charge which was expensive.

If you send a pcm to Diablo, and a photo or fill our their form for your current pcm, the will make them swappable for a $100 plus you have to pay shipping.

Great service. I had them do a pcm for my sold 16 that I only used to up the idle rpm. Truck ran perfectly

Don't send your PCM to Diablo for unlocking send it to HP instead.Lots of guys claim Diablo has ripped them off,and says their pcm is junk,and then tries to sell them one of their pcms,and never sends back the supposedly garbage pcm.
I wouldn't give Diablo any money or PCM these days,ever since Holley bought them out,they've went downhill

My swap went smooth, but I didn't send them mine to unlock. I sent them a fleabay pcm same as mine and they sent me the unlocked pcm. Works great and have my original if something were to ever happen. I've had the pcm swapped for a while now and tried a few tunes. I know vehicle specific tunes are better than canned,but I like the 91 octane CAI tune with my kn CAI and flowmaster flowfx exhaust. Also have the performance trans tune which is actually pretty good in its own right. I'm sure HP may be better,but for my needs the Diablo has been great. Only thing I don't like is how slow and clunky the tuner interface is when completing tasks. I was going to get a hemifever tune,but don't know how long I'll have my 1500 5.7, next truck will be a 2500. Our campers keeps getting bigger and heavier. Loading up now for 6 day trip.

No the guy replied to my PCM question with a sales pitch answer. Like , "Here call my 1800 # and pay me to unlock your pcm" Aaahhhgoooof !

I bought a pcm from a pull yard that has a bulldog tune and was thinking of swapping it into my truck and see how I like it. I have no idea what actual tune the truck has except that it's a bulldog tune.
I do know the truck had the same 545 rfe and the 5.7. It also had long tube and true dual exhaust. Guy at the yard told me that when he drove it to the yard that it ripped like hell.
I got there after the engine and tranny was already sold.
Can you also swap a tipm the same way by rewriting the VIN also ?

some tipms dont need to be programmed its hit or miss I just swapped one into a 17 durango didnt have to do a thing. But yes you can program a TIPM with a good scan tool

The last time that guy was on this forum was a 11 months ago, so probably was not replying to you.















Maybe you are new to forums and aren't familiar with the function of these two buttons?

 

[DripJust]

I never quoted the guy in the first place. I asked a question at the bottom of the thread and he replied to me.
Are you like the forum hall monitor ?

If it is only the alternator charging problem, the most cost effective approach is to wire in an external regulator. Get one from the late '80s / early 90s. It is easy to do, I've done lots of them but not recently.

You must be reading a differant thread then the rest of us,as i don't see anybody reply'ing to your question . The way i read this thread Ken's right ,unless there's a hidden reply the rest of us aren't seeing.
Post #4 is January 3rd 2024,then post #5 which is your post,is a 1.5 years after post #4 on June 5th 2025.
The last time the guy you quoted was here was Aug of last year,so not sure how he seen or replied to your question

I just kinda thought I saw a minor, easy to fix, misunderstanding. That after I pointed it out, he'd go back, re-read post#5 and fix it with a quick edit. I didn't expect that he'd double down.

Unless of course, there was a private message or hidden post. But that seemed unlikely, given the other guys 'last seen' date.
