The past several months I have had starting/idling/stalling issues. This general is worse when the vehicle is cold. It is hard to start without givin... -
1988 Subaru XT, crazy no spark condition
Hamm3y posted a topic in Old Gen.: 80's GL/DL/XT/Loyales...
I usually don't post to forums that much because I'm pretty good at finding issues and fixing them, but this no spark condition is drive me crazy. I have access to the factory service manual for my car. I was able to use it for the MPFI control unit pin read outs for intense trouble shooting.... -
Hey all, I have an 87 XT coupe with the EA82T engine and i'm looking at tuning options for finer control. I was originally going to replace the ECU with a fully tunable Megasquirt 3, But someone had mentioned using a piggyback Power Commander Tuner https://www.dynojet.com/power-commander/ It was one...

Hi guys, I've recently discovered my XT's ECU was fried inside, I took it apart and saw the burnt electronics. For a long time, it had a lot of sputtering and hesitation. My suspicion is that it developed a short circuit. When trying to start it, it would blow the fusible link, I traced all I could...

Any help on finding a 1993 Subaru Legacy sport ecu to engine wiring harness? MT/turbo. I’ve looked all over the place to find one but no luck. -
Hello all Im hoping to get some advise on possibly reflashing my ECU. My 2007 Outback 2.5 is going crazy and I admit I don’t know enough about the Subaru’s to troubleshoot it without some advise. I just gave it a small tune up to get the engine from missing. But the dash is lit u...

I'm doing long-deferred maintenance and repairs on a 2002 Impreza Wagon 2.5 TS. The car was operated by someone who knows little about cars (but drives like he's still teaching the Offensive Driving and Escape Course at bodyguard school. (Once drove 300 miles in 4.2 hours on roads that DOT would h...

Hi all, I am freshly signed up, and also fresh to Subaru's. Must admit I'm a car freak from way back, so I know my way around most old school Aussie sold cars. But when it comes to computers and other new age electrical systems on most modern cars, I seem to have fallen behind. Now I'm ho... -
Hi all, I've been under my dash pulling my electrical bits apart trying to diagnose something and today while pulling out my ECU to get at my fuel pump relay I noticed a wire coming from one of my ECU plugs that's more than a little janky. The FSM lists the wire as being "Line end cord output" which...

Hi Guys, the last two days in a row now I've had a really hard time starting my '87 GL. this morning it took me about 30 minutes of trying, and I finally got it after about 30 seconds with the starter going, and gently feathering the gas pedal juuuust right. It almost started and then stalled a few...

I recently replaced an idle air control valve and the check engine light is still on and the idle is still rough. Do I need to reset the ecu? Or do I have a faulty wire? I'm a bit unsure because normally I've never had to reset the ecu.- 11 replies

Hello, I've bought a damaged Forester XT Premium 2015 and I'm starting the recovery process. While I'm waiting for the body parts I'm focusing in putting the engine to run. First I sent the car to an mechanic and he told me that the engine ecu is not responding, because his scanner wasn't able t... -
Hey Im new to this forum and a bit new still to subies but i have this 1982 BRAT and i just picked up a almost complete EA82T to swap into it minus the wiring harness and ecu so i am in need of one does anyone have one that they would sell for cheap?-- i need every single wire and the ecu and also t... -
This is really baffling me. Could use help. Pulled main relay and it bench tests fine. Had a crank sensor code, replaced with new. Timing covers off and all looks intact. Can see OBDII readout at port, but when I test probe connectors at ECU per FSM, I am not seeing power consistently at PIN 1... -
Hello all, I have a 2002 WRX and I don't know how i could find out if my ecu is the problem. To start from the beginning, I was trying to find the output of my ECU that could turn it from automatic to manual in the hope of getting rid of p1596 error (automatic tranny diagnosis input signal high... -
I might have fried the ECU on my 2002 WRX. Wondering two things: 1 - which ECU's are interchangeable. 2003 Impreza? Found a cheap ECU in scrap yard. Turbo car vs non make a difference? I know the tranny doesn't make any. 2 - Trying to find the right fuse/ fuses? to the ECU. Just in case...

Hello all, I have been looking for this answer for a long time all over the place. I have a 2002 WRX manual. It was originally an automatic when produced, the previous owner got it switched to manual. The thing is I'm pretty sure the wire to tell the ECU it's a manual instead of automatic h...

Hello, I have a 1992 Legacy Wagon, EJ22, AWD. A few days ago the motor would not fire up and has not fired up since. The wagon has not had any motor work done to it for over 3 years. It ran and drove great over these past 3 years. The wagon has never been in an accident. The timming belt... -
Hey guys, first of all I need to confess: I don't really own a complete Subaru (sorry) ... Last year, we swapped a Subaru EJ25 SOHC engine from a 2000 Legacy (156 hp) into our 1973 VW Beetle. We also installed the stock ECU and all the necessary parts from the original wiring harness. Com...

Hello, First post on this Forum! It has been killing me on my 1997 Subaru outback to get the pin connections out of the baby blue B84 connector. I am trying to ground out Pin #81 to remove the CEL for the egr valve. The previous owner swapped the 2.5 for a 2.2. They changed the original automatic... -
Hi there, So I just bought a high mileage 1990 subaru legacy with the 2.2l and auto trans. I went into it knowing there were some issues to resolve, those being primarily leaking valve covers and some throttle body issues. While talking to the seller he told me that the alternator had recently g... -
Hey guys. So I'm planning on doing an ej swap into my ea wagon this summer, and although I was planning on using an ej22, I have easy access to two ej25s. One is a SOHC with an incomplete harness, don't know what it came out of or what year it is. The other is a DOHC sitting in a wrecked 97 legacy,...

I swapped a 97(?) JDM 2.5L in for a 99 2.5L recently. The 99 was driven about 60 miles with no water in it due to a blown hose, nuf said, it wasn't me. I installed the "new" older 2.5 with new timing belt blah blah blah. Timing set up nicely. Even though the JDM was injected, we transferred the ina... -
