I advanced my timing
I;m sorry, i was talking about disributors. Rob at Pineapple changes the curve on his, and says 20/10 is best for performance/daily driving. Also he says that the car will make more power if you bring closer to top dead center at high rpms. CJ

I shouldn't say a thing since I can't get the printer for this computer to acknowledge the printer port, but somehow I flat lose you when you talk about the pin and 10 degrees and how it makes 18 degrees and all before top dead center. Normal timing is 5 degrees AFTER top dead center so if you advanced it the timing 18 degrees then it would be set at 13 degees BEFORE top dead center. Talking LEAD here. I don't know, I'm on drugs right now.

I didn't mean to sound like a ***** about the measument thing...
I was just going to make a degree scale to stick to the pulley so I could be more accurat.
sorry.
and to answer any erlier statement, I wasn't advancing the timing to fix the hesitaion. I did it for power gains. I did everything else for the hesitaition. I thing it might get better after I change my exhaust for the trird time since it came back with this current one.

I came, I saw, I boosted.

HAILERS- Thank you for clearing up what the pin is!!!!
So stock mazda recomended timing is 5 degrees AFTER top dead center.. interesting.
I was assuming I was 18 degrees advanced because an ealier post put the pin at 10 degrees BTDC.
And I have heard that you can bet better high end power with less advance... That's what the aftermarket chips do-
They increase advance like CRAZY in the midrange, it gives better power in that area, but then retard it a bit as RPMS climb high.
I am not sure what the fuel map modifictions are though.
Word of advice- If you are planning forced induction on an N/A motor with stock computer, DON'T use a chip!!!! The major increase in timing advance in the midrange is enough to bring serious detonation issues!!!
The turbo versions of the chips actually retard timing more, to allow for more boost.
Curiosity- Anyone know what the stock advance curves are?? With a strobe I've seen advance at LEAST 20 degrees while revving it a bit...
