I even have the Fields vtec AFC, but my car is still running rich. My settings right now are:

-4@1k
-4@2k
-3@3k
0@4k
+2@5k
+2@6k
+2@7k
0@8k

vtec engagement is at 4400. I understand that there is a diff between a close loop and open loop circuit, but the AFC should be changing both maps at narrow and wide band no?

Are there any other areas I should check? And if anyone has the same ECU piggyback for the b16a, what are ur settings? I talked to a few ppl in my city and it seems as though they all have a problem wirht running rich as well.
