I have done alot of research and still am a little confused on the subject. Are you able to datalog A/F from the zeitronix to the e-01? I know there is a feature in the e-01 to covert a voltage signal (1.75v) to the correct a/f ratio (12.5:1). I have read the info on here http://drizze99.conforums3.com/index.cgi?board=hardware&num=1108992978&action=display&start=0 but I'm not sure what wires to hook up in order for the e-01 to datalog the a/f from the zeitronix or if its even possible. Thanks
