more alky? or add fuel?

[SIXBANGR]

Just did a little test and tune, FAST says I need more fuel. No knock at all at 21lbs. Car ran real good. Should I up the fuel or add alky? thanks

If you have knock, add aly. If your lean.. add fuel.

If your rich and knock, pull fuel and add alky.

Target 11.0-11.2

I like the target number that Razor is suggesting. Just for future reference for anyone that might run 100% methanol, I have been targeting 11.4 with a wide band referenced for gasoline. Any richer and the engine gets lazy.
