I'm considering a cam, exhaust & emanage setup & I'm wondering...
What is the best way to tune for this setup? Timing, A/F ratio or both?
I've searched quite a bit and it seems that there are a number of opinions regarding timing and piggie backs.
One opinion is that cutting back air/fuel ratios will cause the ECU to advance timing. Is this true for a very modest, say -5% cutback durring open loop operation? I wouldn't think the ECU would react too much to -5% A/F ratio under wide open throttle. Also, I don't have to monkey with A/F if going all timing is better. Or visa, versa.
I guess my question is, what combination of timing vs A/F ratio is going to give me the best power gain on a N/A setup with cam, exhaust & 94 octane?
Also, my SOHC distributor doesn't rotate.
