Should I install the S-AFC blue wire? Does the S-AFC read the O2 voltage acurately? I read on another post that it doesn't, is this true? Should I trust the S-AFC or will I have to get a Datalogger? I have a Greddy EGT and a Autometer A/F gauge. Is this enough to tune my car some what properly? Please let me know, thanks.

I tested the blue wire mod awhile back and found that it did cause problems
To make a long story short, the blue wire mod caused me to tune too lean, and I lost power. With the blue wire connected, I saw .92v but it was actually .88v on the logger. Guess it has to do with the resistence issue brought up earlier. I would avoid doing it.

Thanks a lot for your input guys. It helped a lot! I think I am just going to leave it off.

BoostedTSi, I don't really understand the quote in your sig.
Never lift to shift?
Not in an auto, I guess.

What the hell?!? Dont do the blue wire mod? ive never heard that. So i should unhook that wire and tape it back up? I also connected the wire for my A/F gauge to the 02 sensor wire going into the ECU. should i disconnect that too?

If you have a logger, you can check by comparing your A/F gauge and the logger to see if they match or not. If they are off, leave the AF wire connected then recheck with the blue wire disabled.
Go to this website here they explain it thouroughly

Go to initial afc tuning(low) . Instead of buying a a/f meter(waste of money) use the one the s-afc has. You have to jump between the screens while tuning but you get the hang of it after a bit.

Yes but the question is "BLue Wire Yes or No?" I think there are other factors to consider before doing it, not just because of the benifit it has for a 1 time adjustment on Lo-Settings. Those can easily be done other ways. This is just my opinion of course.
