power fc need a wideband?
I just picked up a power fc for my red top sr20 and someone mentioned that they thought i would NEED a wideband O2 sensor for it. is this true? or does it just use the stock narrow band?
if it uses the stock O2 sensor, will the commander give me readings on how lean/rich I'm running? or will i still need to pick up a wideband for that?
