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.

 

Please also post a data log of the surge.

 

Here's the log you asked for, Thanks you guys over at diy auto tune are the best.

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.
