i have a 2005 neon sxt, i just installed (well half way so that i can monitor without chaging map for now) the SAFC-2. i read up info the upstream o2 sensor, its a bosh style o2 that generates betwen 2.5 and 3.5 volts, if anyone has something like the SAFC-2 i would like to know what would be the optimal settings for HP as far as voltage off the o2 goes. ive read up and it looks like it works like a narrow band o2 voltage + 2.5v for example on a narrow band .5v = 14.7:1 ratio so dose this mean 2.5v +.5v = 14.7:1? and if so is .94v optimal
