Go stage 3.

Hook up a WB02 to the EMU.

Turn on I/J map. Set target A/F to where you want it.

Use I/J to add/subtract fuel.

The 360CC base map isn't really for 360s. Its just what the ECU wants to see as if it had 360s.

I highly doubt the map would run worth a crap without I/J adjustment.

It doesn't follow what the car would want to see normally, its just a guess in airflow % via pressure, RPM, 3L, & VE mapping.

Newest 2.16 map I did is actually smoothed all the way across to give steady changes in IDC to help control injectors a little bit smoother.

Like i said, go stage 3, use WB02 to adjust the I/J map, leave narrow bands unplugged.

Find an afr map that resembles stock, get it adjusted where it needs to be adjusted post ECU, then plug nb02s back in, disable target a/f except above 11 PSI.

Done.

BTW, idle surging? Its either between 2 cells and one is rich, the other is lean. OR you have a bad vac leak.
