I am swapping a 2001 R/T Magnum IM and Head into a 2001 SE. If I use the R/T PCM will that work to operate the IM valve actuator or will I still need to use a window switch, etc. ?

The wiring and relay are not there, so the PCM cannot operate the MTV solenoid.

If you add a pin socket/wire to the PCM connector, and wire it to a relay, then it will operate the MTV.

The other issue is most if not all R/T PCM's are SKIM equipped. You will need to add the SKIM module and have the keys from the donor car to make it work.

You can try to just plug the R/T PCM in and see what happens. You might get lucky. If your '01 is skim equipped, you will want to disconnect the SKIM module first.

If you have the PCM, it is worth using, if it plugs in and runs the engine.

Thanks. Maybe I'll get lucky with the R/T PCM. But would it be easier to just use the SE PCM and wiring and avoid the SKIM problem?

Yes, there is a way to do operate the intake butterflies with a window switch and there is a how to somewhere on here.

Thanks guys. I know about the window switch method which I can use with my existing PCM but was hoping that using an R/T PCM would be easier. So what is a SKIM module and how will I know if my SE PCM has it?

The SKIM is the Sentry Key Immobilizer Module.

In longer words, it looks for the correct chip in the key whenever the vehicle is started. If it exists, it's fine, if it doesn't then it shuts the car down.

Easiest way to know is if you have a black key or a gray key. Gray key means you have a SKIM because there is a chip in it. The black key is much thinner and is just a key.

The R/T or ACR PCM has a better tune than the stock PCM. It is part of the 18 hp gain you get from the IM, exhaust header, cam. and R/T muffler. You aren't going to get quite the same amount of power by just installing the top end parts without the the PCM.

Whether or not it is simpler is basically a wash. If the PCM works, it is less wiring and a cleaner look, as far as the relay part. But without the engine harness, you still need to wire the MTV solenoid.

You can use the spare fan relay socket holes in the PDC to keep a clean look if you desire though. But you would need to remove it and run the wires from underneath.

I got lucky, and the R/T PCM I bought works due to a communication bus error keeping SKIM from functioning. The downside is Torque will not connect to it.

Unless you're good with factory wiring diagrams, you'd probably be better off getting a Syked PCM and running a window switch. More power, too.

You could also send it to sidepipe87 and get it reflashed to your Vin if you can wait for a few weeks.
