Carburetor swap

I posted a thread awhile back on the 05 pcm swap. And it’s been nothing but problems. I’m about to give up. Is it possible to put carbs on the gen 3 hemies. How would I control the ignition. Could I just use the msd hemi 6 ignition controller with the same coil packs?

I can understand your frustrations and if you choose to run a carburetor thats your choice. But would highly recommend sorting out the truck before making any additional changes. Good luck..

If you go that route you can just get a megasquirt and use it for ignition control and buy this lovely modman 6 pack carb setup I have for sale!

With a carb. You have to use MSD Hemi6 box, re-adjust the timing for the carb. You can still use the oem coil packs.
Is the carb setup for a Ram truck or a 5.7 Hemi swap into a car?

Looking through your threads, I'm guessing the carb is for the 03 Dodge ram... Don't do it... Get with Keith(charged392), Greg(redtruck) on the problems your having with the 05 pcm. Sometimes, the pcm swap isn't as easy as it sounds...

If I remember correctly Waylon doesn't have a pcm swap problem, he has a skim problem. I'm personally not in favor of going to a carb. But it's his truck to do what he want with. Personally I would take the immobilizer and toss it. Send the 05 pcm off to be skim deactivated and flashed with vin. I'd have to re-read the instructions but that should be good to go. But just a warning, with the immobilizer removed an attempting to use a skim activated pcm may lock the pcm. Regardless when a skim lock occurs, repeated attempts to start will lock the pcm. Let us know what you want to do..

What's a skim lock on the pcm? Immobilizer?


EFI is much better than a carb.

All oem pcm it seems are skim capable. Any pcm plugged into a truck that is skim enabled (gray key) with its immobilizer connected will cause the pcm to become skim active. The immobilizer has a ring around the ignition switch that reads the key when inserted. The key has a pin that the immobilizer must recognize. If recognised the immobilizer then transmits a secret pin to the pcm to operate. If the secret pin is not recognized, the engine is allowed to crank something like 5 attempts. Then locks the pcm and prevents it from further cranking. Once a pcm becomes skim active it cannot be deactivated. I posted earlier a link to a place that has stated they can remove the active skim from the pcm. But I don't have experience with doing this. A new pcm is skim capable, but not skim active until plugged into an ignition that has a immobilizer. It then becomes skim active. A skim active pcm can be set to skim blank and I think can be used without the immobilizer plugged in to run properly, but with a DTC secruity fault. At this point all I can say is don't plug in your clean (black key) pcm into a skim enable truck.
HemiLonestar and YeahItsAHemi like this.
