Default Why is my timing at 0?

I posted this question in another thread on efilive and I wanted to ask here also.

My log and tune can be found here:
http://forum.efilive.com/showthread.php?t=9818

In my log between 16740 and 16760 my timing drops to 0 with no KR recorded and the commanded timing is 35*... What table is causing this? And is this normal? It's causing my AFR to lean WAY out so I wouldn't think that it's a good thing.

Thanks!

Jeremy

I can't view your logs, but if you're letting off the throttle and going really lean, that's DFCO

I followed the directions in the AutoVE doc for disabling DFCO.

BTW - What is DFCO?

What it's doing is randomly nailing 0-10* timing when I let the TP fall to 0%. Then just after the timing drops the AFR jumps to 30-45%.

Found it - The AutoVE doc says to set B3313 to 122c but it looks like B3308 has to be set to 122c for M6 cars. I just went through the directions and didn't look at the other tables the first time around.
