ignition timing and A/f Options

[ncgalant]

Alright, lets get down to it. I'm looking for power. Given that, which is better, a little richer and more ignition timing, or leaner and less timing? Currently I'm working toward the latter, but want some input from some that run fast.

Also, which is better for spool, lean or rich. I can't get my pre-boost #s into the rich range. If I do a 3rd gear pull from 1500-6500. My O2s will read .08 until 3500 or so when they jump up to .8 and then .9 around 4000. My setup is working, but I want it to be the best it can be. I can post up my SAFC settings if you guys want too. Their F'd up.

I'm not seeing the timing flatten or drop. The good thing about running 10 degrees is that when in the worst timing bracket(most load), the ECU pulls timing at a drop of a hat. When I am pulling the load and getting more timing, timing doesn't get pulled as easily.


I guess you guys are also thinking in terms of 1g ECUs. For a 1g, 17 degrees is quite average, for 2gs that's pretty good.

Not sure what you mean by that first statement: it seems to me that you're saying that with more timing, it's less apt to get pulled. Is that right? That suggests to me that you'd want more timing. Unless I'm misunderstanding

Hmm, actually 17 is a little on the high side for a 1G. There are a lot of guys w/2Gs that have 22-24* timing advance at WOT and seem perfectly happy w/that. Seems like it's kinda high to me, though.
