Hi, this site is for all that want to repair, upgrade, or swap to EFI.We can all find small articles and buy many thick books but until now there has been no one stop on-line site for EEC questions.After reading many books and finding all the articles (on-line and in magazines) I started to answer question for many people.These questions made me realize that there were no good on-line help sites; I hope everyone can come to this site and feel comfortable with their EEC vehicle.These pages will primarily detail Fords EEC-IV (with Ford Trucks), but will include principles from other EFI control systems and vehicles.I also plan on turning to EEC-V in the future, just as carbs are being swapped for EEC-IV, EEC-V will be the future.Lets not all start sweating, I've already started my EEC-V research, and I’m kind’a excited.The Ford EEC is very special, tested, and proved around the globe.It has been estimated that Ford has sold more computers than IBM & Apple combined.The EEC has been tough enough to survive Desert racing 125+MPH into rocks, and quick enough for Indy racing’s 200+MPH @ 14000 RPM.Enough facts, lets get to the reason your all here.
Every one say hello the EEC.Once hated by many, if understood properly she could be your best driving partner.Unlike previous technologies that would be affected by environment changes, EEC looks for these changes, reacts, and uses them for tuning.

EEC.What is it?
Electronic Engine Control.Remember this is the quick explanation for more click above.EEC-IV is a computer, it has a memory and chips and stuff inside.It “listens” to all the sensors, decides what the environment you’re driving in is like.It also listens to what the driver is doing and what you want to do.It decides what the best air to fuel mixture should be and what the timing should be at.It continues to listen making sure the outcome is what you and the EEC want it to be.Example, you smash the skinny peddle, she puts the mixture to around 12:1 and the timing around 32° BTDC.The engine revs up and you fly down the road, she checks to make sure the engine makes it to 4-5 thousand RPM and the car is speeding.Click below for further EEC philosophies and how to start:

Sensors.Do I Need All of Them?
Umm?Yes and no.This is dependant on where you live and what you are trying to do.I do not use all the sensors designed for the EEC-IV system.But I’m not you.Sensors check tons of stuff:
·Engine position during rotation
·Whether the engine has too much timing
·The temperature of the incoming air
·The temperature of the engine
·How far you’re pushing the throttle
·If you’re pushing the brake or clutch
·What Sea level you’re at
·How much vacuum the engine has
·The amount of air it’s ingesting
·If it’s running rich or lean
·How fast the vehicle is going
·If the Air Conditioning is on
·If you’re using 1000 AMPS from the Alternator
WOW, that’s a lot to think about every 0.000001 seconds!OH wait, we don’t have to, EEC-IV will do all this for us.She decides what is happening now and what is going to happen 3 seconds from now.That’s smart, too bad it doesn’t always work as planed.Hmm, now we have a reason for this site.Click below for further sensor uses and testing:

Actuators.Acting a Fool?
Ford Eec Iv System
Actuators are the thing-a-ma-do-dads that gives fuel and spark to an otherwise really big paperweight.After sensing what is going on we now have to act on it.We need fuel, not just poured in, but measured amounts.We need timing advance, not just adjusted with the unreliable engine vacuum, but pre-planed programmed limits.What about pumping the throttle to keep it from stalling?HA, that’s covered too.OH NO, the government called, we have to make the exhaust smell lemon fresh.Now we need some exhaust recycled in the engine, the catalytic converter to burn more toxins, and the possibility to use cleaner fuels.CLEANER FUELS!We ain’t burning rice here kids; we’re talk’n Methanol, Natural Gas, Propane, and 100+ octane fuels (remember I said EEC-IV Indy cars).Click below for further Actuator uses and testing:
Tools.Does a hammer count?
Umm.Not unless you’re testing the knock sensor.You can’t change the jetting on these things.First we have to under stand why I said; “she could be your best driving partner.”EEC-IV listens to all the sensors, acts on them, and wants to tell you what’s wrong with her if there is a problem.There is already a great article about reading codes from an EEC-IV and I’m gon'a leave it alone.I've submitted some extra pictures and a more in-depth list of codes.Click here for that page.
Ford Eec Iv Schematic
Most of the EEC-IV engine can be repaired with normal tools; there are only a few buys necessary for repair.There is also a wide verity of professional tools that are on the dream team list.Some can still be bought today while others are better found used.Remember that EEC-IV is OLD, EEC-V is the future, and probably outdated as I write this, an EEC-VI will be on the way in a few years.EEC-V is harder to deal with, but once the right tools are had and Ford releases some of its locked files, it will be a lot easier to use, trust me.Click below for all the cool tools:
