No im not saying the turbo is blown. If its black smoke it means its running rich. Wht bov are you using? if its the stock recirc. IT MUST BE recirculated. it sits open and idle and will cause you to run rich. if not then what kind are you running?
i have a type rs style BoV off my friend 1g talon tsi, it is recirculated. and yeah im running crazy rich cause my plugs come out either charred or soaked in gas..
the car is only smokey mainly cause of no DP also.. but its definately running mad rich. i think its cause of a leak but idk where ive pressure tested everythign. ive been swapping out GTIR sensors for DE sensors like crazy too. im pretty stumped.
hmmm check your maf voltages. it might be starting to foul out. and wait your running the gtir ecu right? if you are leave all the jdm sensors dont put in usdm ones. it will cause the ecu to get false readings
i didnt really get to hit peak boost because the car would hit 3k break up and run like sh*t, so i turned the car around and parked it.
I caught this while reading the thread. IMO, from previous reading, if the MAF is faulty, you're going to have this problem. IDK for sure, because I don't have an SR20det, nor have I had this particular problem, but a majority of what I've read points to this.
From what I've gathered, if your MAF is faulty, you will also run rich (as a precaution to prevent you from running too lean).
yeah i think your maf is faulty. and swap back to the gtir ecu before you blow something up. they de ecu doesnt have the proper tune on it to support the motor. the gtir ecu has different ignition and fuel maps.
if they are like the ones on the de or det the run together and then y off and one goes to the pcv valve and yes they have to be used they cant be open or capped as far as i know.
Later,Jon

im not sticking with the DE ECU im just trying to solve my idle problems before i ship out my ECU to calum =( and i cant run the GTIR ecu because the car wont run at all. im not driving it just trying to fix the idle.
hose from you pcv/crank case vent(10o`clock on your VC if your reading it)
.....this bleeds already metered air >pressurized< from your crankcase to your ITB's on the back of your butterfly-plates....the screw's ADJUST this passage...
....IF YOU HAVE THE EQUIPMENT TO TUNE THESE, THEN YOU ALREADY KNOW THEY ARE NOT TO BE MESSED WITH.
.....THIS IS FACTORED IN THE DECELLORATING METERED AIR,.....
.....if you have maf and you cap all of these, and run the pcv tube to atmosphere or a positive pressure(intake tract) , ....they your probably having an issue of stubling upon closed throttle and decel.....
...there's 2nips X 4tb's.....cap half of them, T the rest together with the Pcv tube...
.....this is my understanding of this system.....turning small screws should be done in a controlled environment.....
if you have time to make digital art, post it here
if you have some graphix , fonts, ideas, that you don't have time to illustrate, post it here
and beeee veeeeerrrry
i just checked my motor. starting from left to right
1 and 2 are tied together
3 and 4 are tied to gether
then the 2 you have that have been tied together already go into one big hose that goes into the valve cover on the back passsengerside.
....../\/\ exactly, .....you have 2 nips on each TB. On each TB the one Directly below the adjusting screw gets capped the other gets T'd to the PCV(positive crankcase vent) tube..(the threaded check-valve @ 10 o`clock on the valve cover)..make sure the pcv is in working order, use a vac pump to pull it open or remove it and poke the backside with a nail to make sure there is spring in the action, ifnot replace it.....that was the problem....
...ifnot, atleast you've got a working pcv system now....and you can check that off the list as a possible cause for the crappy idle.....
...If that's not the case, what fuel pressure are you trying to start with?
ok ill check my pcv out and check how its hooked up. idk my fuel pressure but ill get a guage and test that too. should be fine though im running gtir fpr and a 255 walboro
