for the ppl with AFC in their cars, did u tap into the O2 sensor wire??? i've read that the signal is under lots of load already. tapping into it will result in signal loss which makes A/F ratio not accurate which takes away the point of connecting it.

any comments on this?

 

i cant speak first hand for an evo, but ive done the "blue wire mod" on more than a few dsm's with no problems whatsoever.

 

yeah, thats a great mod, it wont hurt your signal unless you cut the wire... DONT CUT THE WIRE!!!! just peel back the outside and solder, or wrap the blue wire around it. easy useful mod.

 

i think it should just be used as reference to a separate o2 gauge. it's a ***** switching back and forth between screens.
