idosubaru Posted April 18, 2008 Share Posted April 18, 2008 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?

RallyKeith Posted April 18, 2008 Share Posted April 18, 2008 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.

idosubaru Posted April 18, 2008 Author Share Posted April 18, 2008 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!
