Ford Fuel Injection
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.
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:
����������� Go to SENSORS
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:
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.
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:
