yeah the exhaust is hooked up. I had the downpipe custom made and for some reason didn't have a bung put on it for the sensor.

that little sensor not hooked up is the IAT (Intake Air Temp) Sensor. You might wanna hook that up, a hole drilled in the charge pipe and some jb weld will do it.

Definitely get that o2 sensor hooked up, usually that will make you run ridiculously rich.

Also, thermal99.com for some AFC Settings.

got the o2 sensor installed and now i have a different problem:

the car wont go into boost at all. it just bogs out and sputters when it sees boost.

was messing around with the spark plug gap because i had some backfiring. i found the least amount of backfiring around .4 - i suppose since i got the o2 sensor installed things could have changed. should i try gapping them at .3?

make sure you're fuel pump is good. i have a walbro 255 and it had the filter it came with on. i mounted the oem honda civic filter instead of the one it brought and it runs better and idles better. the honda fuel filter that goes mounted on the fuel pump is way less restrictive then the one my walbro255 fuel pump came with. also, do not T off the FPR. get some 5/16" plastic Ts' and T off the charcoal canisteemissions filter, and the PCV valve, both of those provide better vacuume/boost source power then the FPR. also, i had my BOV/wastegate hooke upto the FPR for a boost/vacuume source and i was running leaner that way with the same vafc settings then when i hooked up the wastegate/bov to the pcv valve for the BOV and the emissions charcoal canister for the wastegate. just check your intake manifold for hoses hooked upto it that are bigger then the regular vacuume hoses and T off those. make sure it's not the ones under the throttle body for coolant. test the hoses disconnected for vacuume before you cut anything.

did you hook all the stock sensors back up by now? You really should have all the required sensors where they are supposed to be to eliminate some of the possibilities.
