oh man kid. youll want to get a wide band a/f guage. and its easy to install. youl have to probably drill a hole into your exhaust before the cat. and install
the a/f sensor into that hole.

cool thanks also i've noticed the motor is running a little rich i know its probably because it may not have got a ecu tune when it was swapped but i dont have the money to do a ecu tune so is there anything else i can do to make it run leaner atleast for small amount of time so i can get it to pass emissions by the way it is a blacktop sr20

your best bet would probably be an apexi safc. are you sure its running rich. and not lean?

I' am very sure its running rich it is only at idle though i know because when i went to get the saftey and emmissions done they told me it was and sometimes when i first start it up it spits black smoke out the tail pipe until it warms up, what is the safc and how does it work
