The distributor uses a 24+1 gear setup and this is the hardest part of the whole build to get correct because the MS will come pre assembled with only one VR circuit installed and you need two (one for the wheel with 24 teeth and one for the wheel with 1 tooth).

there are ad on boards avaliable however that carry a few extra circuits that you might need such as the extra VR circuit, boost control circuit, extra coil circuits to run COP or wasted spark, water injection and others....

as stated every thing else is quite easy to do... its the building of the extra circuits to run the distributor that is the hardest part of the build...

what most people do is adopt the ford 36-1 VR wheel and sensor to the 4efte to make things easier and run the stock ford wasted spark ignition system.

this may prove easier to some who may not want to add on the extra circuits and such.

some people (like me) modify the teeth in the distributor to give a 12-1 signal which can be handled by the one VR circuit on the MS board...

obviously these also take up a bit more experience and time to setup

edis-4 was my first choise but after discusing with some members here says that is no need for edis and trigger wheels and extra vr sensor and ms can take control of the standard ignition easily by no mod in the distirbutor or the board.
Was on a beta code tho...

Have some rep for your inputs!!!:rockon:;)

thanks...

the new stable code that is now out can handle running the stock distributor...

i'm about to try it, but due to mine running so well i just cant seem to find the time to take it apart to add in the extra circuits :)

ohh BTW the idle valve is mechanical so no need for any electronics there.

From of the top of my head i believe it is an on/off switch type and you need to on the valve till the point the coolant reach the operation temp.
Am i wrong there mate?
It is nice someone seems to want to share infos about ms installation.

it is mechanical.

it is at the bottom of the throttle body with two coolant lines running into it.

once the coolant is cold it stays open and when it gets warm it closes....

the idle valve is that thing on the left of the plenum as far as i know :|

i found a pic of my board fitted with the extra circuits in the top of the case

S6301854.jpg


heres one with my jumper harness which allows me to run the stock wiring
(basically plug and play)

S6301859.jpg


S6301860.jpg


i broke apart an old ecu to get the connector then basically traced each wire from the MS to the connector using a pin out diagram

that is used to stabilize the idle but it has nothing to do with the fast idle valve...

the fast idle valve increases the rpms when cold to about 1200rpm and then drops to about 900rpm when warm

if you look at the bottom of the throttle body you will see it with four black hoses running to it... two of the hoses are for the power steering fast idle valve and two are for coolant.... :)

BTW the valve on the left of the plenum is not needed when running the MS

i have looked into my EMS(no MS, but KMS).
i have choisen the DIS ignition, with it's own trigger pich-up.
Triggerwheel is 36-2 with hall sensor
accoring to my info stock is hall sensor on the camshaft.

single coiled ignition.

idle is 3 wire, open - ground - close(could be wrong by mistaking it with 5E one)

EDIS option could be nice

only big problem i'm running in to now is not working RPM meter, wrong kind of signal.
i have taken out the oridgional ignition/distributor.

thats what im planing to do :)! cheers bud... any more info you can share with us??

well i'm using all stock sensors... apart from the auto throttle body with the variable TPS...

some newer 5e engines and the newer 4e engines use a 3 wire idle valve none of the 4efte comes with those..

the signal from the distributor is a VR signal

the rpm meter wont work since you changed to a DIS setup you need to get a tach adopter from MSD or the like......

so i can work with all sensors and just source an auto tps?! thats great! :)

sure :rockon:

i'm even using the stock GT map sensor :p

even though its only limited to 1.1 bar :(

the map sensors in the kit can handle up to 1.5 bar
you could even order the kit with a 2.0 bar one as well ;)
