any one on here know anything about ford eec-iv engine controls 1990 (maybe used in a project car?} need ecm  or source for rebuild. checked local parts stores ,no longer available! Thanks gerald

My encounters with them was in Speed Density systems, both on 302 and 460 equipped cars. Best bet will be junk yards.  The distributor has a module attached to it with a muti pin connector, again both 302 and 460 applications.  No idea if that ignition control was used on the later Mass Air systems.

Rockauto recently had a remanufactured OBD 1 computer for my '95 Lincoln 4.6 dohc, so maybe........
I had looked there a number of times before I actually found it. I just wasn't looking in the correct section.

Google - ECU reflash service - You will be surprised how economical this service is.  If you use a shop that is close to you, go over and talk to them with photos in hand.   Then gather up what you need.  Mount what you can yourself.  Then make an appointment with them, and have your car towed over.  Yes, spend a few bucks to do it right, and do not hand them a mess or stand over them.

Also, remember that OX sensors are directional.  If they go in wrong, they will work...for a little while.

This will be money well spent.

The 1990 year the op posted would be OBD1. Most "local" shops cannot work/modify/rebuild the obd1 system ECUs. OBD 2 started in 1996, and got more complicated in '97 with the Passive Anti Theft inclusion.

OBD1 does not need to be flashed.

hey all.thanks to kultulz for the link to eec-iv systems. got my unit rebuilt by an outfit in south florida. after two other companies looked at it. not a lot of support for those early systems. first rebuilder said "missing parts" can't rebuild. charged me 275.00 dollars!! ended up costing 675.00 from south florida. but, whatyagonado?. still turns on check engine light randomly.never had that problem when i first built the car.thanks,Gerald
