Swapping Navigator 5.4 DOHC in S197

[2BlownStangs]

What are you asking for the heads?

silly thing popped into my head, now the older 4.6 2v/4v used the same heads now i know you can't use the 3v heads on the older 4.6's without a lot of modifications, i'd assume this would be the same for the 5.4' 4v's

Bringing this thread back up because I want to make this happen...

Talking to Tanner today and he brought up the fact that a stock 3V harness could potentially be able to run this, does anyone have confirmation if there are any additional sensors on the 4V motors?

This setup has 3v pcm running a 4v.

I still have my navigator bottom end, timing cover, and cam covers *cough* buy em *cough*

It will run it. It's really just a head swap, that uses the same sensors.. Remember our discussion?

Yes Tanner, I do lol. PS: In the thread lightblade linked the guy had to add an extra cam position sensor...

Trying to figure out the intake manifold situation.

Yup no way around that really since there are 2 more cams.

I think jpc make a 5.4 manifold.

Already have a JPC 5.4 3V manifold, I would most likely do the Reichard racing plates and a 4.6 4V manifold. Spent about an hour and a half bullshitting with Tanner on the phone and learned a lot, but still don't know which manifold I should go with.

Funny that the 4v doesn't have VCT and it would require more than one cam sensor when it doesn't from the factory..?

Just saying..............if you keep the stock harness and computer, what are you going to do with the either cam sensor on the engine and in the tune?

Good info here

I guess you know better than Mike Bowen and I.. Interestingly enough the GT500 doesn't have 2 sensors and it runs off the same PCM with a different strategy.. That tells me that the PCM is capable of running the coils and the single sensor. If I had my laptop (sct-adviii) in front of me, I'd tell you exactly how to do it.

So, what did you do with the other cam sensor?
We all can wait until Tuesday.

Subd great info

 

[Kuro!]

Tanner, so what you were saying was that the PCM would be unable to use one sensor with both tapped in because they PCM thinks they are in different locations at different times?

 

[Natural1]

So here's the deal.. I still believe it can be done with one sensor. From what I can tell, the PCM uses one sensor to monitor cam position for actual engine operation, like the 4V does. It also uses the same sensor to monitor and adjust the VCT for that same bank. The other sensor seems to be used only for its respective VCT operation. It's possible that it uses and adjusts for both banks for not only the VCT but everything else as well. If that's the case, then it would pose a definite challenge but is not impossible by any means. Like I said, I'm positive it can be done and the PCM could run it this way but I don't own an IDS/VCM. I will have to agree that adding the other sensor to the sensorless bank on the 4V would (no doubt) be easier.

Mach1, is the coolant head temp sensor still located in the same place on the 4V heads?

Nothing changed there.

I don't remember the tweak though in which the data is used in the 3v computer though.
