What the heck is this?!

What is with the double 3992's and the odd timing dropping to 0 then right back up? Also, how can I manipulate my fuel curves to get my timing to climb faster and a bit higher?

Hmm, that's kinda weird. What kind of logger are you using? If PocketLogger, do the byte timing test to make sure your connection is stable. I have no idea why there's the double 3992. Your timing's kind of weird though, usually it drops down pretty low around 3k to 4k then starts climbing up, though that's on the 16g. Where do you hit full boost? What're your settings on the S-AFC?

I am using PocketLogger. Connection has 0 errors on it for over 2 minutes. Uhm...Full boost is hitting around 4200 RPM I'm pretty sure (kinda busy watching the road...). I thought it might have been a lean spot from the boost piling on all at once so I added some fuel, but no change. I did another log and it was the exact same thing. Timing goes from really high to zero to back to high. Bad thing was, on this 2nd log I only was able to get 11 degree's of timing at 6300 rpm. *sighs* Damn V-trim, I wish it'd make its mind up. SAFC is running in the -23 to -31 percent range for the 650's.

Hmm, that's weird...give it a bit more fuel at 4k and see what happens. I'd also take out some more fuel from 5k to 6k and like 3% out at 6.1k

Actually, I've got DSMLink not (just not installed) and while cruising the forums there, I noticed a problem people had with the FIC 650's. Many of them had similar spiking issues at around the same RPM range. Haven't found a cause or cure yet though... Back to researching!

Ah, best of luck then!
