Just thought Id throw this up for any tips you guys can give. The maft calibration is off a little but the butt dyno tells me its pulling harder than it did last year. The second log I zeroed out my timing. It felt about the same but got less knock. Let me know, thanks

6-17 was a whole lot better. Look at your timing advance on the other log. Average if you ask me. Put the timing back and either lean it out or add some boost. You can go to ask much as .7-.9* of knock retard before it pulls timing. I really like the 6-17 log.

Your big timing it at 2.6g/rev. Just kidding. But, try leaning it out and see what she does. If not, give it another degree or two of timing. But I think another pound of boost or so and a little less fuel and your golden. All looks great otherwise. What fuel pump are you using, it doesn't say in your porfile. Those 650's have a bunch of room left.

Thanks for the reply. Im using a 255 fuel pump, must have left that out of the profile for some reason. If you display the plx wb youll see that it goes rich at about 4800 and stays that way. Ive tried to lean that out and i get some knock. Ill try to pull some more fuel out there this weekend. Im still pretty new using link and messing with timing.
edit* I should add that this is on 114

Ok, didn't see the wideband. Pull timing back 2* from 4500rpm and on. Then try leaning it out and see what happens. I would shoot for between 11.5-12:1 AFR. You have too much timing advance to go any leaner. Pull the timing back and lean her out and she will start flying. You may not get as much advance when you do that, but you won't be flooding the motor with fuel and should yield some positive gains.

Your getting as much as 25.8* advance at 5952rpm. So pulling timing back 2* shouldn't make much of a difference there. But, taking away fuel will make a good size difference.
