Unhappy Idle surge 95 Diy PNP

I just installed a diy pnp in my miata it started great on the first start, but it was really rich like 10-11 afr. So I looked in the fuel table and turned down the four blocks until it looked reasonable like 14ish. As I was turning it down it slowly developed this surge that would go from 400-1000 rpm. I included the tune so you guys could take a look. This is first time tuning.

I'm getting a message that the download failed due to a server problem. You might need to host them via Dropbox, or you can email them to me at [email protected] (just include a link to this thread in your email).

Got the log. Try flattening out the VE table in that range and adding a little more fuel. If not running sequential, trying to idle in the mid 14's is hard to pull off.
