hey read!!, well... Options

on my celica i have a few mods and my cuisn tweaked with the timming a little bit and if u know what im talking bout the timming was set at 16 and it used to be at 5 and i noticed it gave it a lil more power and it kinda sounds a lil like its "caming". but it drives better and i have not noticed any problems at all..
what do u guys think about this i would like ur info......

bringing this one back from the dead.. ive done the seaches (i have 18 pages open on my desktop and i've read them all)

I LOVE!!!! all of the info that you all have provided here on the board reguarding advancing timeing on the 7afe (in particular), and it seems that most of you are running @89oct for the 5sfe w/ 15* advance, and @91 oct for the 7afe w/ 15* advance...

my question that has not been answered by reading all of these pages, pertaines to the fact that all i use is 93oct Shell V-power.. thats ALL i use (and when i do long road trips, where there is a chance that i cant get it, i always carry octain boost w/ me.).

so. with that in mind does any one els here run anything more advanced than 15-16* advanced on 93oct fuel? i was contemplating going to .. say... 18*advance.. but was not sure if that would be too far off the peek of the optimum effect of the timeing parabola... (did i lose anyone yet?) i do plann on taking it slow, and doing a test and error tune, starting at 15*advanced. and going up from there.. but as we all know, the but dyno is'ent exact.. probably not even enough to feel the diference between 15* and 18*..

has anyone dynoed on 93oct @ 18* advanced???
or 17, or 16, or even the concensused 15*???

i doubt that i would get any knock or pinging w/ 18* on the 93 oct fuel... but i guess what im REALLY wondering is... even IF the fuel suppressed the knock, is the timeing parabola small?

( a 10* spred factory setting of 10*advanced to say 20*advanced,... which coud explaine the common 15* advance to feeling like its right on the point of the parabola thus producing the best power.. and takeing this to be true if i set to 18*advanced im actualy falling off the other side of the peek and 18* would do nothing better.)

or large?

(with a 20* spred factory setting of 10*advanced to say 30*advanced,. and takeing this to be true if i set to 18*advanced im actualy still climbing closer to the optimum ignition timing point of the parabola peek and 18* would do something better.)

????

Any more proof (dynos and dyno charts) personal expiriences, advice, constructive critisysm on my theory, ect ANYTHING!!! would be greatly apriciated...

thank you in advance <<lol)
