ej22t swap making it legal

[Zendriver]

I'm going to call CCR Engines tomorrow. They said they'd find out some details in regards to this ECU coding/data that the BAR referee was talking about. This is what I found out so far, kind recapping...

1. The BAR doesn't know what year your engine is unless you supply them with a document stating that it's the correct year for your swap. They will not look up engine block production stamps or research anything when they do your inspection. You need to provide the documents. You just need a document that says it the correct year. An invoice that says it's the correct year is good enough. That's what I was told.

2. You need to pass a visual, functional, tailpipe.

3. The ECU will tell them what emissions standards your car should have. I believe anything from 96 down will follow the same standards. This is the part that needs some more researching. Exactly what does the ECU tell them?

4. Also,the ECU will tell them what engine you have 2.2 L Turbo or NA.

5. You need to keep everything stock especially in the emission area. You need to have all of your catalytic converters. I believe the BAR guy said that the turbo legacy should have 2. Is that right?

Hmm, supply a document? What if someone was to fire up office and visit the Microsoft template site http://office.microsoft.com/templates/ to create my own company and put whatever the heck I want on an invoice...


The engine in the junk yard might not be in good shape. The intake had black chunks in it. The connection for the oil filter got snapped off (I took the cooler) The timing cover is broke. The headers got ripped off the engine. I took a good portion of the intake and the electronics from the strut tower. I also grabbed the LSD and rear brakes. The ECU is gone already. The hood is destroyed, plus it was a replcement from a previous accident (no emission stickers, shipping tag still present on the replacement bumper beam). The shift lever is gone and so are the sun visors. The seats arent in good shape.

I could go on but basically its not worth it. The junk yard that its in is actually a Pick & Pull dedicated for imports only. On whole row dedicated to subarus. They even have a Brat with bull bar.

THAWA: Dont think your the only one to know about the Legacy's in the junk yard...

Here's the issue though. There is no way for the BAR to know this unless they have a select monitor.

I highly doubt they are going to keep computer diag equipment for all the cars out there. That is why they standardized with OBD2, so they could read different cars with one scanner.

Pre-OBD2, everything was proprietary. Unless they have a select monitor or fancy computer scan tool, they won't be able to tell.

I am with Josh on this. I couldn't find any definitive documentation on this stuff, but here are so old testimonials from Honda guys. It was kind of nostalgic reading this stuff that I saw as it happened 5 years ago *sniff sniff wiping tear*

You can see from these thread that some of these guys had aftermarket parts on their cars and passed. And the refs. were pretty easy to work with. These guys are not cops! And as mentioned some sort of reciept makes it all a lot easier...I don't think you are going to have a problem if you have the ECU for a Turbo Legacy and all your smog stuff...

[THAWA]

I dont think that, I was just suggesting it to him, Good to see most of the parts went to a good home, I jacked the alt though . I wish they could get more soobys though.

CCR Engines just called me to confirm that the ECU will tell you what MY legacy turbo it came out of.

Dead cars do tell tales. Damn. There is hope because if you find a 93 ECU you're good to go regardless of the engine year, 91-94, it will still work.

[Matt Monson]

That may or may not matter. If you read the testimonials I posted, those guys do not talk about them running an OBD-I reading off the ECU. But with the changes in emmissions standards getting tighter, they may be doing it differently 5 years later. Regardless, your Vin is a '93 so you are cleared for take off(see other thread)

The Legacy Turbo ECU did go through several revisions. There are five part numbers: 22611AA690 through 22611AA694.

If my information is correct, 690 through 692 were used in 1991. 693 was used in 1992, and 694 was used in 1993 and 1994. I will double-check this, but I'm pretty sure it's right.

So the part number of the ECU can give away some info about the model year.

I don't really know much about OBD-I readers for Subarus. I know a few companies made them, but that is all. The Select Monitor is the only scanner officially certified to properly interface with our ECUs. When you use the appropriate cartridge in it, mode F00 of the scanner displays the year and engine, "1993 2.2L TURBO" for example. It does this by reading the 3-byte ROM ID from the ECU. Like Josh says, it's unlikely that the BAR would have a Select Monitor on hand. They might know the part numbers though. I don't know how official-looking a part number sticker has to be...

This is independent of the Federal/California issue. An ECU sold in Maine is the same as an ECU sold in California. The wiring harness is a little different, as I said in another thread.

All the turbo ECUs are interchangeable, so you could certainly swap in (temporarily or permanently) a later ECU. In fact, if you were to go to a dealer and ask for an ECU for a 1991 Legacy Turbo they'd order you part number 22611AA694.

I do have an extra 694 ECU that I've been using in my experimentation. If someone has a 690 through 692 ECU, or maybe a 693, I might be willing to trade for the cost of shipping...

[vrg3]

Okay, I double-checked it, and I was almost right.

690 through 693 were all used in 1991.

693 was also used in 1992.

694 was used from 1992 through 1994.

Most Select Monitor cartridges are only applicable for one model year, so they'll always report that year. For example, I can hook a Select Monitor with a 1992 cartridge to a 694 ECU and it'll read "1992 2.2L TURBO" but the same ECU and monitor but with a 1993 cartridge reports "1993 2.2L TURBO."

Also, as far as I know, there is no 1994 cartridge; the 1993 cartridge is meant to work on 1994 models as well. So I don't think any Select Monitor will ever say an EJ22T ECU is a 1994 model.

There is supposedly a cartridge that handles all BC/BF Legacies, but its existence has never been proven as far as I know. :)

So, anyway, some 1992 EJ22T ECUs could pass for 1993 ECUs.

I know this is an old post, but I thought I would give my two cents. I spoke with Thawa recently about his car. He had a 91 LS, he swapped in a turbo legacy engine, turbo, ecu and the like. He later then put in a TD05-16G, and an ecu from an EJ20G. What I don't know is if he had the 20G ecu in there when he saw the ref. He have had the stock one in there.

Point of the story was that when the ref went to check the codes, he didn't really know how. Thawa told him about the connectors, they hooked up the connectors and the computer started spitting out all kinds of codes.

He asked what they were and Thawa basically spouted out that one was the neutral switch (since he changed from auto to manual) and a few other things that weren't really emissions related. I don't think it was all accurate, but the ref took his word for it and gave him a sticker.

I don't know what the rest of the process was like, but it sounded like it wasn't as big of a deal as we fear it would be. I wouldn't bank on being able to BS your way through it all, but if you look pretty stock, pass emissions and things pretty much line up, you are probably most of your way there. A few little things here and there (like getting an engine from an older car) may not matter. You just need to show that the engine you have was sold in same make (not model) car of your year or newer. OBDI definately makes this nicer as less information is used directly from the ecu for testing and diagnosing.

[Legacy777]

You can pretty much bypass or fool the OBD1 ECU's so they don't spit out codes. You just need to know the specific information on the sensor you're trying to bypass. Even something like the neutral switch is pretty easy to hook up when you do a MT swap.
