Rich Z06

I had a custom tune done on my Diablo Predator for my '02 Z06 with long tube headers, cat & X pipe, and new air cleaner with Shaner TB. Nothing extravagant.

I didn't bear down hard on the go pedal, obviously, so high revs aren't evident here. But still, I'm just a bit concerned about the timing advance in the 2K to 3K rpm range. Any opinions?

Next time out I'll try to log in the 4k+ range to see what the data looks like.

BTW, this log was created using the CarChip module, in case that makes any difference. It only takes samples at 5 second intervals.

I'm using a link here because I think the file size may exceed the limits on this forum.

Thanks for any help.

Usually when they adjust timing, they just adjust it for WOT areas. The timing you see in your log looks normal. My car sees upwards of 41* stock from the factory when I let off of the gas.
