Alright, those marks mentioned in the web-site are on my pulley. I suspected that they meant +2, -2 degrees. So, if I read the article right, I should line up my marker with the bottom notch to advance my timing?
Uh, oh... I spotted some contradicting instructions. "The one closer to you is another -2 from your factory setting" and then later, " Everyone seems to recommend 18 degrees BTDC so that would be the mark on the crankshaft pulley closer to you assuming your standing in front of the car." Egad, which is it?
Ok... so I set my timing so that the marker was lined up with the top notch, reset the ECU, and took it for a spin. It quickly became obvious that I had retarded the timing because my car was sluggish. I pulled it onto Admiral Wilson Blvd. (a 4 lane road with a speed limit of 40, although everyone agrees on 90) and floored it. Acceleration between 60-90 was unbearable... I never even made it to 90 although I had plenty of time to under normal circumstances. I got home, adjusted it so it was on the bottom notch, took it for a spin, and it was much peppier. Now I'm resetting the ECU. So, anyone who reads this post in the future, set it for the bottom notch to advance it. Thanks for the help anyway.
I wouldn't say it's entirely psychological. When I was trying to figure out which way was advance and which was retard, I set the timing to retard first, and took it for a spin. Nothing was noticable until I hit the open road 60+ acceleration was crap... I gave up trying to get up to 80 after a decent amount of time of flooring it. When I got back home, I sent the timing the other way and the acceleration came back and was slightly improved over normal timing advances but it was definitely better than when it was retarded.
