So I was trying to dial the car in, noticed my airflow per rev and combft was way off, I managed to fix the airflow per rev to .25-.26 but my combft is at around 30%?

My 02 doesn't cycle at idle its dead at 0.02v... If I rev at all it cycles/drive but the combft is still way off.

The sensor isn't very old, my coolant temp sensor is connected and working fine.

I ordered a new o2 sensor and will try that when it comes in.

Just thought I would ask here if anyone knew something I didn't.

No boost leaks.

Mods are:
2g maf
stock turbo
ets gvr4 kit
dsmlink v3
560s
rewired evo 9 pump
dks 272s
Manley springs and SI valves.
block bored .020 over.


here is the log

Just noticed the jumping from closed to open loop while driving, maybe I need to set the threshold higher.
