so i just got in my new A/F guage today and went to hook it up

low and behold nothing ... just 0.00 reading ...

my 02 is a bosch 3 wire sensor .... one black wire from the 02(ground???) connects to the green wire on my car ... then there is a plug w/ two white wires ... w/ the engine off and ignition on i checked the plug that goes to the ECU... wire #1 is 12V and wire #2 reads nothing (so i assume that's the wire that is sending the ECU the signal for the 02 reading no???)

all of this is @ normal running temp .... well i called the tech and he said that its because my 02 doesn't put out enough power for both the ECU and guage ...does that make sense???? he said i need a 2nd 02 ... BAH ... well i still have my old one BUT the 2nd 02 bung in my downpipe is about 2 feet back of the turbo(and other 02) ... if i did try to install it here how different would the A/F ratio read??? biggest thing i have against that is that its gonna be a bitch to try to break the bolt out that's keeping the other bung closed... so well ... anyone have any idea's???

was recommeded i maybe upgrade to a 4 wire 02 ... or buy the 02 from the company that i got the guage from that way if neither work i can get my $ back for thier products being sdgkhasjghadg

hm... so yea .. thanks
