Hey all,

Heres my Question. Is what nissan calls the Mass Air Flow Sensor the same thing as the "O2 sensor"?

Let Me break my problem down for you all. I have future plans of turbocharging my 2001 Max.
So I am slowly buying parts that I will need (i.e. Greddy e-manage, & an A'PEXi Auto Timer for turbo).
I just got the A'PEXi Turbo Timer and I want to install it, but I am unclear on one part of the instructions.

It says Splice the white wire (O2 sensor signal) form the relay (the timer relay that is) into the O2 sensor wire from the ECU.

All help is greatly appreciated!!! Thanks Devilish

They aren't the same thing... the MAF is up on the intake manifold while the O2 sensors are down on the exhaust manifold/y-pipe area....

For TC questions, there is a Forced Induction forum as well, where TC discussions are more commonplace...
