Which ECU for 1996 Legacy?

Featured Replies

I'm trying to pick an ECU for my EJ22 swapped Legacy sedan...and there's a ton of choices for a 1996 EJ22 Legacy:

 

22611AC271

22611AC431

22611AC910

22611AC930

 

Is there anyway to find out, does anyone have a parts catalog, or does that not even show the differences?

Is your car a 5spd or an automatic? I'm assuming you swapped a 2.2 in place of a 2.5 I did the same thing and swapped in the ECU from the 95 2.2 I installed and it causes a slight issue with the trans shifting. The 95 2.2s have a lower redline rpm than the 2.5s. with the 95 2.2 ECU you can hit the rev limiter in 1st gear for about a second before the trans shifts, because the TCU thinks it has another 500rpm to go. This only seems to happen in 1st and it only happens during a foot to the floor pull out, but it does happen. Other than that you're fine, but not gaining anything. I swapped mine hoping I would get better fuel economy but it didn't make a difference. The stupid 4.11 final drive ratio just kills it.

Keith, yes I sort of swapped an EJ22..it's an EJ18 with EJ22 electronics on it. It's an automatic (FWD, I swapped that in too).

 

What was your swap...what year is the vehicle? A 96 ECU might be better....read on.

 

A 1995 ECU would not work in my car for some reason (and it was a late model 95 ECU). Wouldn't start. The EJ25 ECU runs fine and the 1996 EJ22 ECU works fine.

 

I had slight hesitations with the EJ25 ECU. When I swapped to the 1996 ECU it seems to be smooth now, no little quirks like it had. And yes, gas mileage is lame. But I got a nice cruising, bulletproof EJ with leather seats, lots of big brake and wheel upgrades, and a sunroof!
