beat my idle issues...I think
I went at it again.
Changed my OFL scaling to 550/550, (I was Dynoflashed with 680s).
Added 30% fuel at 0% load from 500-1500rpms, added 20deg timing in same zones. Did a few log runs, tweeked my fuel and timing, now I have no knock, and 11.25:1 afr across the board.
I just started it up after letting it cool for 3 hours, started right up. Idle was a little shakey, afr was 17-18:1, I added another 10% at idle (now 40%). Now it idles well at 14.5-15.5:1, still a little lopey (I have cam gears at -4/-1 with 272s).
I am happy.
I did have some knock at 6500ish, (Al noticed it when we flashed also. He ended up taking out alot of timing there. We figured it was probably resonence (sp?)noise.), I lowered my knock sensitivity from 6000-7000 from 33 to 31. I also bumped my knock count to 4 and max deg of retard to 7.
Do you think this is to aggressive?

Sounds about right to me.. You might want to set your scaling to 680/680 (It nets the same value, but if there are any minor calculations for injector size in OLF it will let them work a little better)
Force an ECU reset so your trims are zeroed out again, then do another bit of adjustment until you are happy with it.. Then once the ECU learns things will settle down a bit more.

I did do an ecu reset, but not because of the OFL tune, because I couldn't get my laptop to handshake with the UTEC.
Everytime I would try to access the UTEC, with UCC or Hyper term, it would only show the tuner.
I finally had to put the 9V battery in it and just turn my key to access. to load my map.
I haven't been happy with this USB connection. I think I need another USB adaptor. To access thru Hyper term I have to do the "feces thing".
