In order to remark the AEM gears correctly, you just have to put the stock cam gear next to the AEM cam gear, (or right on top of it) then use a scribe or some other similar sharp pointy metal object to just cut a mark into the AEM gear.
Obviously, make sure you are very careful and do it correctly the first time! You can't erase that kind of mark. You could use a pen or a marker, but it will eventually wear off, which is not good and why I just scribed a new timing mark on mine.
>now you said 8 degrees advance intake....does that only mean
>4 marks on the cam gears?
Yes.
....thats what im confused at.....i
>have mine at +2,-2....(2 little marks) does that mean im
>actually at +4,-4....
yes
im lost now....and how could they sell
>these cams for our cars and them not even be correct
because they ae meant for a Neon. they saw the neon and the eclipse had the same engine, and the cam gears are the exact same size and part (well, except for the location of the timing mark) and just said they will work for our cars too. They do work, it's just the marks are not in the right place, they are off by about a tooth or half a tooth on each gear.

>remarked them....
That's always possible. It won't be EXACTLY in time the way it is supposed to, but the car will still work. When I put mine on the first time, I didn't mark them and the car ran fine. It idled poorly, but once it got above 1500 rpms you couldn't tell the differenc e(except I wasn't making any mroe power).
But once I marked the cam gears correctly, re-installed them and had the timing perfect (car idled normally), I was able to accurately tune them on a dyno and get more power out of them.
If you had the correct timing marks, and everything was timed perfectly, I'd reccomend going about +6 or +8 degrees advance on the intake cam to start with, then go from there if you can get on a dyno. Since your marks are off a bit, the best thing is to take it to a dyno and do all of your tuning there (if you are unwilling to take everything apart, mark the gears in the correct spot, then put it all back together again)
There might be some issues with making optimal power the way your car is now, with the exhaust cam being off (since the cam angle sensor magnet is attached to the exhaust cam), but if you adjust the exhaust cam gear the correct amount to compensate, (don't ask me what it is, I have no idea, you'd have to compare where the AEM mark is tot eh stock cam gear, figure out which direction it is off, measure or estimate how many degrees it is off,t hen adjust the AEM gears that much to compensate) then you should be fine.
