That looks very agressive for 93. I just got a Bin file from a guy that was running C16, and his advance is much less across the board.

On 8.5:1 compression he ended up at 14 degrees up top.

BTW, what were your A/F's looking like, and what is your compression ratio?

I have a Turbo M3 (3.2L)

In the end we are all running boosted straight sixes.

Thanks for the pic. My A/F ratios fluctuated from 11.1 to 11.8:1. I have a BL 2.5 mm headgasket so my static compression is around 8.7:1. I took Justin's advice and few other people's and retarded my timing about 3 degrees.
Datalog a few runs. I would love to see them.
