Hey guys, my car hasnt been running right and i just got an "ECUTalk" cable to hook up. My tps was way off and was informed to adjust that first and then go from there.
So i adjusted the tps, it now ranges from 0.5v closed, to 4.14v full throttle. I then adjusted the idle screw, down to about 750-800 rpm (is that a good idle speed?). this caused timing to set back to 20. The idle is still fairly rough. But nevertheless, AAC% sat at around 41% the whole time, tps and 0.5v. O2(brand new) ranged went back and forth from 0.04-1.43. (i've heard it should go back and forth between about 0.2 and 0.8 ( so this causes me to think the mass air sensor again). Air flow at this idle is 1.20v, and injector mS at 2.13-2.24..
I do have a spare maf sensor i could hook up (not sure if it entirely works, and need to get the connector to hold better than it seems to be. But what do you think of these numbers? Thanks for the help!

spot on


> the idle screw, down to about 750-800 rpm

should be 850-950


> timing to set back to 20

correct


> O2 range went back and forth from 0.04-1.43

that is also right


> i've heard it should go back and forth between about 0.2 and 0.8

GTI-R has a 1.5v o2 sensor


> Air flow at this idle is 1.20v

should be 1.0-1.5v at idle, and 1.3-1.8v at 2k rpm


>need to get the connector to hold better than it seems to be

check the voltage of the afm connector ground wire (white - middle), should be under 9mv at warm idle
