O2-sensor on carb (sorry) engine - Slant 6

[Mike Olsson]

     Dear EFI-gurus,
     
     I threw out a question last week on EFI for the slant 6. I didn't get 
     any answers, so I guess there are not many of you out there who has 
     tried on such a project.
     
     I've contacted some aftermarket sources and there are a handful to 
     choose from, but there are two major problems: I don't want to be the 
     first person ever trying to make this work - I need to get some 
     feedback from anyone who has converted a slant 6 to EFI. Please, if 
     you know of any such project - let me know.
     
     Secondly - it's really too expensive to invest $1500 in an aftermarket 
     system. With my lack of experience I could end up with a system not 
     much better than my Weber carb.
     
     
     I believe I have a very versatile and "tweekable" carb (Weber 32/36 
     DGAV) and it should be possible to get it run close to optimum at most 
     speeds. I can adjust, individually, the fuel-air mixture for idle, 
     low-speed, normal speed, full throttle and acceleration for low rpm:s 
     as well as higher rpm. The problem is that I find it a bit difficult 
     and time-consuming as the different systems affect one another in a 
     complex way.
     
     
     I understand that the fuel-air mixture for example at cruising speeds 
     should be 14,7:1. I want to get my carb as close to this as possible. 
     My idea is to install an O2-sensor and thus benefit from it's readings 
     to optimize the carb.
     
     What is the actual electrical output from an O2-sensor (mV, mA, ohm)? 
     I would like to connect it to a meter placed at the instrument panel; 
     giving me the best possibility to adjust the carb.
     
     Any help or advice is greatly appreciated.
