Engine Control Module- So many options?

[Chapap]

There seems to be several types of ECMs available. I imagine there’s 4 basic types: California or fed emission, and Auto or manual. But there’s several different codes I’m finding within those four categories. Is there a way to figure out what I need without pulling mine to get the numbers?

‘94, 2.3, 2wd

Just pull yours.

I not sure but I think the VIN would work

That won’t give you the calibration number.

You need to look at yours and read the calibration number off of it. It's on a sticker attached to the ECM. That's the only way to be sure.

Well looks like that’s the only option. Mine most likely is original.
What do folks do if they suspect a previous owner put the wrong module in, or the sticker rubbed off or something?

Edit: just got off the phone with my dealer. They were still able to look up my calibration, engineering, and part number. Will check it with what’s in the truck.
He said my calibration is 449SR00
Part is F47F12A650BGB

I don't know if a dealer could look up the correct one based on the VIN...that might be an option? I guess if what's in there does not match what's available for that year I'd be suspicious... our trucks are getting to the age where it's hard to say what's been messed with unless you have a clear record of owners. I know my old Bronco II, for example, had a flood salvage tag on it from Florida, then went to North Dakota where it sat in a barn for 15 years after the owner died. After I sold it I saw it for sale at least 7 or 8 different times. It's kinda shocking how many times they get passed around and messed with.

PM your VIN and I’ll see if I can find it in OASIS.

Also check the door jam for a sticker that says “calibration”.

I didn’t type fast enough. See my edit in my previous post.

Doesn't oasis only go back 10 model years?

Post photo of sticker on ECM.

Not every time. Wound up with one that was marked with a 2.9 manual part number that had a calibration for a 4.9 auto.

This.



There exists in the internet a list of all available EEC-IV / EEV-V calibration codes. I think TwEECer or some other tuning site has it. It's semi reliable, but not always correct.

You're looking for the three digit code on the ECM that's in your truck. Kick panel, passenger side. Just post a photo of the bar and numeric codes on the 60 pin adapter.

No guarantee that it's the right one in there, though.

Typically, if you're having trouble with an EEC-IV, the electrolytic capacitors on the primary board shit themselves. They are typically only good for 20 years. Lots of instruction out there on how to replace them.

I can look some stuff up all the way to ‘94... not everything.

Is there a trick to getting the connector off? I tried unscrewing the bolt and it feels like the nut behind it is spinning in its housing. No budging from the connector

I had the shop hack the old one out. The new one (BGB) resulted in a no start. The ECU in the truck is ADC though. That’s a relief cause BGB is near impossible to find. There appears to be two ford numbers on the original computer. I assume I’m looking for the one on the sticker.

This is a good thread I found. I’m very pleased that he said ADC is the comp to get as it matches what came out of my truck

2.3L ('83-'97) - Correct ECM to get? '93 2.3 manual.

Heading to the junkyard soon for an ECM (or four) to try on the "SPOUT issue" 1993 2.3 manual. My understanding is that we'll need a 1993-1994 unit that comes from another 2.3 manual, and the last three digits on the box are the specific programming. 2wd/4wd doesn't matter but EGR does. '94...
