Default 6th Gen. 1999 Accord F23 OBD II - Questions on Cat. o2 sensor and 450cc Injectors

Hola hombres!

60% complete turbo kit build.
Still need: DSM 450cc injectors, F23 Manifold, Downpipe and Flange, AFC

Working on welding exhaust system from cat to muffler.

Question on O2 Sensor for the Cat.

I was wandering if anyone knows how to bypass the o2 sensor on the catalytic converter. If the o2 sensor reads anything out of threshold, then i get a CEL and my idle gets really bad.

What are some solutions for tricking my obd II ecu into thinking that the cat's o2 sensor is within threshold? I have read about o2 simulators, but that is still a confusing topic.

Question about Bigger Injectors and AFC's
I have learned that the 5th gen accords require a resistor box...Does the 6th gen, obd II accords Also require a Resistor Box if using 450cc dsm injectors? Or do I have one built in?

Also, will the Apexi SAFC (not SAFC II) be sufficient? How do I "Tune" it? I went to apexi's site but didnt find good info.

Question about F23 Manifold
Anyone willing to custom fab me a Log Manifold for $200 shipped?
I am using a t3/t04e hybrid...cheap china turbo, but rebuilding and balancing it at buddy's shop. Also, i have a Greddy
thanks in advance all!

I got an O2 simulator but it didn't work for me...I hope yours does...mine was an eBay special....looking back I should have bought the real thing. oh well....

I think most people when the boost the f23 convert to OBD-1...makes things a lot easier. I looked into boosting and converting and it seems like the only problem was that the speedo might not work due to the VSS differences. Realize I never did this I only read posts about it. I encourage you to do the same before you go in any direction: OBD-1 or OBD-2. Good luck!
