V10 swap questions
My question to anyone still doing v10 swaps or may know something about pcm from these f150..will the factory 4.6 pcm run the v10? Ofcourse after the extra plugs were added for the fuel injectors and COP's..I've heard the drivers for the v10 are already in the late model 2002-2004 f150s..So that would mean once all the wires were rerouted and in correct location we should have good start up,in fact the pats system would all be unchanged..Just thinking...I have a factory v10 engine harness that came with the motor so I could get the connectors off for the injectors and other sensors..My truck has a 4r70w in it and would like to be aby to drive the truck for a minute to work the bugs out before I think performance..Any thoughts on this subject would be great..Thanks in advance..

The 4.6 PCM won't run the motor because the program does not know there are 2 more cylinders in the 4.6 version.
The crank sensor can't supply the correct timing info to the PCM with 10 signals from the crank tooth gear, cam position sensor will have extra pusles not expected etc.
Even if the 4.6 PCM was equipped with extra firmware, the program won't run, timing, extra fuel injectors or coils without complete reprogramming.
4R70 was not designed for the extra torque if your planning on towing or hot rodding the motor.
Pats might be an issue if the truck the V10 came from had it.
You have bunch of things to address before the motor will ever fire.
Good luck.

Have you read completely through the other V10 swap thread that you posted in?
Here's another V10 swap thread that may answer your questions:

Very good info! Yes I've looked through ishootstuff's thread and Camden's too..Ishootstuff was awesome and sent all his extra data he saved up during his swap..I have the motor on a stand right now not going in til it warms up..I think i'll just send it to 5startuning or somebody that knows v10 tunes..
Now that you say it,ill go with the 4r100 because building up a 4r70w would just be a waste,lol...
I will take lots of pics of the swap and try to post them..Its going into a 2002 2wd short/reg cab truck..It is a sport version and I ran the vin on my FMC programa and it has 3;55 gears and LS..Rear-end might explode too,who knows..its just a toy..Thanks again guys for the post..

Rear end should hold up unless you really beat on it.
Without reading the whole threads again, I think the computer is going to be an issue - a 4R70W uses the ECM but the 4R100 uses a separate TCM module if I remember correctly.
Now - you could always put a 3" body lift on it and swap in a ZF manual! There's a thread around here somewhere where a guy swapped a ZF into an Expedition. If you do that, you will need a custom driveshaft anyway so you might as well swap a 9.75 rear into it.

The biggest problem with such a project is you have to have high self confidence that you can handle it.
There is no one to help. You become the expert and engineer on all that goes on.
If you make a mistake, you are still in a learning curve and may have multiple issues all at the same time.
This is where you need to know how all parts of the system works and be able to relate to the issues presented.
Just this makes a lot of people abandon the project after awhile, then what's left is just parts.
Good luck.

Talked to trans tech today and he said the 4r100 and 4r70w use the pcm..Each have different drivers for the vss sensors..He said the pcm will freak out on the varibles and will probally go into limp mode.
option 1: reflash stock pcm from outside shop for v10 drivers and build up factory trans to handle v10..As far as speed this is the best way to go because of less rotating mass vs 4r100
option 2: Build up a 4r100 and use a stock pcm from a 2wd e250..reflash and reset pats and match my cluster to the pcm..
Lot to think about..
