That is the correct place to start, but.....

That's correct.  Good thing you read the fine print before wasting your
money.

There will be soon...In my garage :-).  I am collecting the parts now.
Keep your eye on that new hot rod F-150 pickup.  It uses the 351 and the
E4OD.  I don't know enough of the details yet, but given the performance
it is likely to use a Mass Air processor.  Ford may make a kit available
through SVO.  I have not seen it in the '93 catalog.  Other than this
pickup possibly, nothing has SEFI/Mass Air and E4OD.

My current understanding is that the E4OD has a separate controller, but
it does connect to the EEC-IV engine controller for information.  There are
some sources for "performance" shifting upgrades, which replace the E4OD
module.  Using the incorrect EEC-IV would cause endless headaches. I am still
waiting for new service manuals (that should arrive "any day" now), which
will confirm this information.

I wish you lived closer!  I would provide a personal tutorial, along with
all of the parts you need.  I would not recommend this project for a novice,
unless you have alternative transportation and deep pockets to purchase
"experimental" electronics.  You could start out by purchasing a few hundred
dollars worth of service manuals for your truck.  These would be the
standard service manual and the Powertrain Control and Diagnostic manual.
I have not yet seen a very good publication that describes these electronic
components and their use.  Most just regurgitate what is found in the
service manual.  The best way to learn is by doing...small projects with
help from Performance Engineering (tm) magazine.

>Thanks for any help

I will keep your name on file and send any information that I collect.
