13 Chrysler 300C 6.4 Swap Issues.

[Hippo]

Swapped a 6.4 from a 12 Challenger into a 13 Chrysler 300C. It runs but it throws p0013, p0335 and MDS codes for all four solenoids which throws it in limp mode. I changed all the parameters in the ECU to match a 6.4. I've tried using the 300 and Challenger engine and MDS harnesses. The issue doesn't change no matter the harness. Any one have any experience with this?

return the cam setting to stock and retest

the cam doesnt know what cam it has in it, and engine hard coded degree for 5.7 different than 6.4

[Hippo]

I offset all the cam values by copying the 6.4 values over and subtracting 10. I think my issue is I have a 13 chassis and a 12 engine. I'm gonna have to pull the damn crank out and swap reluctor wheels.

I don't think so. Look at my sig. Check wiring.

Keeping my eyes on this one, I'm doing a 12 Challenger SRT 6.4 (forged internals) swap into my 13 M6 5.7 CHallenger. I'm curious to see what sorts of issues I run into. I did swap all of the sensors from my 5.7 on the 6.4 just to try to minimize any issues. I'm thinking I will have to copy many of the 6.4 tables into my 5.7 programmed ECU.

I am curious if the SRV will work if you are using the 5.7 PCM? I have seen lots of guys swap the 6.4 intake on the 5.7 but they use the MSD switch. Always curious to see if you enable it on the PCM and wire it to the PCM if it works?

I have seen it done - not sure what all it took to make it happen. It might be some of that secret sauce magic.

Seems simple enough but have yet to hear of anyone on the CT forum successfully doing it without the MSD switch.

Even the plug can be bought as a kit from mopar.

The signal is PWM, eventhough they are using an on/off switch to run it.
We just hijacked this thread.

OP - make sure your grounds are good. You're getting a VVT and a crank position sensor code in addition to the mds codes.

12 and older hemis use a different thickness crank trigger than 13 and newer. This is an older 6.4. I checked all of my grounds. I even swapped back to the 5.7 harness and the issues persisted.

[spoolboy]

Well, if you're sure, go ahead and pull the motor and get to fixin.

[Homer]

Ah crap, accidently deleted my post trying to edit over the phone. Anyways, here is some additional info on the differences between the crank relucto.

Here is another post the supporting that there is difference.

I stand corrected then. Sure seems odd they would do that.

I had a friend do this and ran into a few troubles. Took the PCM and had 6.4 OS put on it and the car worked flawlessly after. So if you are still using a 5.7 PCM, I would look into that. Oh and before the had the PCM done, they tried just copying tables over... never worked right.

That makes me think there is a pin issue at the PCM. Has anyone compared pinouts between the two applications?

I would certainly try this before yanking the engine, especially if you can just put in the OS that is looking for the early crank trigger.

[Homer]

Pinouts can be found here. Would be nice to know where the engine came from and where the PCM came from?

Although if you look up a PCM for a 2013 300 it is used on a 5.7 and 6.4.

That is correct, but that doesn't necessarily mean that the pinout would be identical.

How is that, the P/N for the PCM I show is for a 5.7 or 6.4 so how can it be different?

Pull up a 2012 6.4 Challenger and a 2013 5.7 300C and lets see if the pin-outs are the same.
