well i recently accquried a logger and did a few runs with it..the only tuning device i have is a S-AFC2 and i wanted to get some info on how this log looks to anyone who has gone down this lovely road of tuning

this log was @ 14psi on a FPbig28...there is a small dip in timing in the upper 4k area but only by 1 degree(which is prolly 2-7 counts of knock) and after 5k my a/f curve balances out and timing begins to advance again..the dip was bigger but i messed around with my afc settings and got it down to 1 degree of retard(3% correction @4600rpm)..my o2 is very erratic but im not tuning off of o2 only timing just because o2's are very unreliable especially the stocker

stock 450's and a 190lph other mods upon request

Im guessing thats rpm l timing l o2? What are you safc settings

 

just 3% correction at 4600(high) other wise everything is zero but i just found out that my timing is not supposed to look like that it supposed to be at like 15-19 through the whole gear so i have to find out why im having such low timing...boost leak>>>?


edit: well i think i was misinformed the guy that told me that my timing is bad is running a 1g and i dont think he knew i had a 2g
