I am doing the same with my 4ktq conversion. I plan to use a FMS ECU
(www.fms-oem.com) with the VW digifant injector insert, and a TPS sensor to
replace the entire air metering plate (yipeee!!!). The only other  sensor
that really needs to be added is a hall effect sensor to pick up two pulses
per rev off of the cam sprocket. The FMS unit can use all of the other sock
sensors from the MC w/o a problem. The ECU fires in batch mode as opposed to
multipoint. Graydon Stuckey already did this conversion on his old 5ktq, so
I'm not treading in unknown water.....just shallow..... I'll be fabricating
my own fuel rail, and the only other hiccup was that the throttle cable cam
(on the MC intake) was quite close to the #1 injector, so after a lot of
staring and thinking I found that I could (relatively easily) move the
throttle cam over to the other side of the TB. Looks stock even! That freed
up quite a bit of room for the injector and rail. I'll have pics posted
(maybe even later tonight) at: www.mswanson.com/~nstuart/4ktq

Here is a _very_ basic run-down of the parts needed (I will be creating a
website in detail for this, and maybe even make up some kits of some sort if
there is enough demand...)
-FMS LS-12 Ecu
-5 Digifant injector inserts
-5 EFI injectors from a Ford T-Bird Supercoupe, or a Buick Grand Nat.(I
think) (these cars used the largest bosch injector for the US market, I'll
probably be using some more common injectors for now, until I find a squshed
T-Bird SC in a yard or somethin' working on a budget ya know....)
-Fuel rail, and pressure regulator (custom fabbed)
-TPS sensor
-Hall effect sensor (custom fabbed trigger setup off of the cam gear)

For now I will be using the Mac-11 ECU for timing and boost control, but may
at a later date switch over to an after market setup (though I don't see
much need).

There are also other setups out there that work quite well, like Haltech for
example (www.haltech.com). They also have a  tech mailing list (e-mail me
personally if you want to subscribe).
