AFC Help Really Rich and Timing Retard???

[SDSGSX]

Hey guys, I just got my fuel/turbo setup installed. I have 550's Big 16g 190 fp afc and the normal stuff. The problem im having is that i have the afc at around -4 accross the board for the hi's. At WOT my 02's go to 1.00 my stft goes to 0 and my timing drops to a miserable 8 degrees throughout the gear with no advance. If I keep flooring it in 3rd to tune and it keeps going to 8 degree will i break it??? I was thinking it was doing that because it was 2 rich but i wanted to richen the car up to like +10 just to experiment and see what my timing did.....im just worried that ill break something. Thanks guys

WAY to rich, try around -15 and go from there.

Don't bother logging STFT during WOT tuning, you only set the STFT while idling. For WOT tuning log RPM-timing and front O2 for now thats all you need even though O2 values are almost unreliable for tuning, they can give a rough idea where you are at.

so then the fact that im rich is causing my timing to sit at 8 degrees.........i mean i guess i know the answers because ive read all the threads ...but im afriad that if i lean it out ill blow up...whats the best way to go about doin this since my timing is already at 8 going richer would only hurt me so i guess ill go lean and just hope i dont blow the car sky high?

thanks any suggestions on how to go about doin this would be great =)

just lean it out a little at a time till you notice your timing is starting to go up...then you know you're gettin close Just dont go too lean all at once ...
