Default Timing belt not done right? Timing off?

I'm not sure what might be wrong with my EJ20G, but I'll go thru what's happened. For reference, I'm using the Apexi FC.

Got it started up, ran for about 10 minutes with an idle around 1300. It was a real steady idle and the engine sounded good, rich though and a very very small shake from the engine. After those 10 minutes, it started going up and down between 700 and 1300 and then it finally bogged down and died. Now when I try starting it, the idle is so rough, it just dies. Especially when I go to open the throttle, it'll just stall.

The Apexi FC tries to correct rough idles for the first 10 minutes of it being plugged in and being ran. That's why I think it ran fine for 10 minutes and then died.

I know how to do the EJ20G timing, it's just that it was hard to line up the lines on the gears and belt cover because I think the covers were a little bent.

So if my timing is off a tooth or 2 somewhere, how would the car run? Any way I can check it? What kind of count can I use to count the teeth?

timing belts can be a bitch.. A tooth or 2 the car can still run.

I've seen some toyota's with the belt as far off as 4 teeth, and it ran.. barely.

I've seen timing chain engines off 2 teeth, and it ran, but horribly at idle.

So it's definately possible? How can I tell for sure? My Apexi FC shows ignition timing.

here ya go. rotate the crank till the key way is pointing straight down. take the crank pully off and look at the gear. It should have a little white slash mark poiting straight up towards the notch on the guide.
the passenger side cam gears have green notches on them. There is 1 single notch and 1 double notch. line the double notches up to each other. Those gears you can rotate by hand.
the drivers side has the same set of notches. BUT DONT JUST TRY AND ROTATE THEM BY HAND. they will not move.
Take a 10mm allen and rotate the intake cam (upper) clockwise till the 2 notch mark is at the bottom.
Then rotate the exhaust (lower) COUNTER CLOCKWISE till the 2 notches line up with the intake notches. At this point use a set of needle nose vise grips and gently clamp the two gears together and re-install your belt.

Yeah, like I said, I know how to do the timing belt. I just don't think everything lined up perfectly. I'm looking for some support on that theory.

only way to find out is by pulling off the end covers and checking the marks with the crank position mark...there's no other way to tell

Yeah you need to check all the cam markings and belt markings and make sure they are aligned.

a mirror helps.

I figured out a new trick when installing a new belt on a 4 cammer. take a piece of tape for the lower cam gears and line it up on the timing belt line. Let the tape hang off toward the front of the car so you can wrap it around the front of the pulley...it tells you immediately if the line on the belt is aligned with the cam gear.

I'd just do the job over. pull it all apart, take the belt off (the marks shouldn't be worn off yet) and start again.

If it was right, the marks on the belt would have matched the marks on the gears. Bent covers wouldn't have mattered if you paid attention to the other indicators. Need to pull the covers and crank it as suggested to check it...

Personally I think it is related to the PowerFC and getting it wired and/or tuned properly...

I agree with Matt, your trouble is FC related. My car ran a 12.1 with both Intake and Ex cam gears off 2 teeth. The car ran ok just had a miss up high. If you are a tooth off you might not even notice it. But you still need to check that the timing is right. A genuine subaru timing belt with the white lines makes the job almost idiot proof, just align the lines up with marks on gears.

Timing is all good now and I'm starting to think it's the FC also because of how rich it is. I don't wanna lose my maps but I guess I'll reset it.

I bought the car with the FC and maps on it but I've changed the performance mods a little, so that's probably why it's doing that. I guess I'll reset it and cross my fingers.
