wondering if anyone knows which wire comming out of the ECU is the signal wire for the O2 sensors? I am going to install a AFR gauge and need to tap this wire. thanks

 

im pretty sure you dont want to tap in there. go in at the wires directly by the o2 sensor, by the exhaust. there are 3 wires, red, black, and white. i think. i also think that the white on is the ecu wire, but dont quote me on it, im not 100% sure.


edit: on second thought if your hooking up a guage, then maybe its not a good idea to run the wire all along the bottom of the car, unless it is going to the left or right bank o2 sensors

 

Narrowband A/F gauge is just shy of absolutely worthless.

 

its a waste of time to install. Are you trying to tune the car. what Mods do you have? Do you know how fast a narrow band gauge move. You would be better off tunning with one of these!

 

The stock narrow-band signal is worthless.



Light show time!!

 

well since I dyno'd the car after the NX install it showed that im running rich at wot all the time and even worse with the n2o of course being a wet kit. I ended up going with a the smallest fuel jet that came with the kit since according to the dyno info it runs 11.3-11.8 afr all the time anyway. I was going to get the small square digital gauge from dynotunenitrous to just keep an eye on it and then I hoped to get an SAFCII and mess around.. im not sure what else to do, the car only runs rich at wot, runs great, spectacular gas mileage, what I think is alot of carbon or unburnt fuel(black s*%t) in my exhaust tip. im kinda stumped

 

There's a definite pattern recognized in this thread.

WB > NB

Couple your SAFCII with a wideband 02 sensor that tapped/bunged/taking radings before the cat. (test pipe maybe)

If I may suggest a wb, try the PLX R300. Affordable, and able to take readings of 5 different sensors. And you do not need to 'purchase' a separate RPM converter (i.e Innovative)
