Default idle problems, running too rich, wastegate putters, need help

hi, my setup is the following..
95 integra b18b1
t3/t4
turbonetics deltagate wastegate (9psi spring) with vac and boost connected
drag manifold
custom 2.5 downpipe
450cc injectors with resistors
safc -50 all the way across for low and high
intercooler with 2.5 piping

my problems...
1)idles really low, if i go past 1k rpm and then press in clutch, it doesnt go to idle 700rpm, it goes straight down to 0 and stalls.
2)my a/f gauge reads all the way rich, doesnt move even at idle.
3)my wastegate seems to "leak", it releases gas even at idle it "putts"
4)boost seems to kick in around 4-5k rpm *maybe fine?*

please help, i just installed this and dont want it to die on me

-50% is lean, try -45 for 0 - 1000

Injectors were balanced? you could have a leaky injector, whats fuel pressure at? Has the car ever ran ok? or it just happened when you did the injector install?

yeah i know -50 is lean, but i did that on purpose since my setup is running rich, but there was no change. i think it might be o2 sensor, but it must be right, since i am stalling out.

no the injectors werent balanced, i dunno fuel pressure, and the car always ran good before turbo setup. i first installed the injectors to test them when it was NA, it ran fine with the safc....hmm weird, now i think it really might be the o2 sensor, cuz i bolted on the turbo assembly next, messed with the downpipe and o2 sensor.

i have disconnected the vaccum for the wastegate, and now it dont putter, but it also doesnt reach max boost to 9psi, it only goes to about 4psi. it will probably work after i disconnect the boost line as well.

i am also getting cel when max boost is near.

i bought a new o2 sensor, i will install tonight, hope that solves alot of my problem

I think this is the same problem I had. Make sure your map wire for the afc is right.... if your reading a cel when hitting boost. Your Map is reading boost. Double.. no Tripple check your wiring.

Also on the afc are your sensor settings right? Pressure 06in 06out... 0 for all the other sensor types. And 4cyl with throttle up?

yup, those settings are right, and i checked my safc wiring,and its all fine. oh btw, the 2 grounds ..brown being closest to ecu, and black being a little away from the brown wire, how far did you have the space in between these 2 wires?

imo just do the smc 500.... you can't believe how good my car runs... starts up fine everytime, idles like stock, boost transition so damn good... and my gas mileage is better than stock....
