Hi guys,

I dropped my entire spark table 2 degrees to see if it would remove the seemingly random 1 degree knock retard spikes that I see in my logs or if my knock detection might just be too sensitive (the latter seems to be the case since the knock retards still happen).

Auto-tuning with this milder spark table resulted in a VE table that has slightly less fuel in some areas and slightly more in others.

What's the significance of this? Is more fuel to hit the same AFR always more desirable or wouldn't it necessarily mean more power?

Thanks,

No idea what you're asking, but yes less timing requires less fuel and your autotune works off the target table to adjust ve table how you want it.

I reduced timing. That led to a reduction in fuel to hit the same AFR in some areas of the VE table. In other areas, it seems to want more fuel to hit the same AFR.

Is this because I ran too much timing in those areas to the point where I am loosing power or would that be jumping to conclusions?

That would be my impression, although I'm sure there are more factors that go into it. If it was knocking then it's certainly reasonable to think that you may have gained some power from pulling a little timing.

This is why you rough in your fuel map, then tune timing.

Then fine tune fuel again. Yes.

Just hit with hammer and run 10:1 at all times
