Do I have a narrow band or wide band O2?
Hi: I've just finish the installation of my dry cell in my malibu 2001. I have this set up: 13 plates 3.5" X 3.5" 316L plates +NNNNN-NNNNN+, which is producing 1.5 LPM. at 20 AMPs running not too hot. now, I guess I need to install an EFIE (digital preferably with LCD for reading values). but I'm not sure what kind of o2 sensors I have, there is one pre cat and one post cat, both four wires, I've read that I need to tread the pre cat sensor only. so, any help will be appreciated. thanks.

They are both narrow band. I recommend this product: http://www.fuelsaver-mpg.com/store/digit...-band-efie . You actually want to use an analog EFIE for your downstream sensor, as these work best. Digital work best on upstream sensors. You have one of each.
