Steven, I applaud you and your attitude towards engine management. I have also broken away from the distributor ignition and gone "electronic", well sort of. I have every component in the system backed up by a secondary. Having the oxygen sensor is a good idea. You will probably have to set the mapping of whatever controller you use by tweaking a few parameters while monitoring performance at various RPM ranges with the mixture pot set to a neutral position. After that you can make it run richer or leaner by setting the mixture pot to where you want it on the O2 meter. I am currently doing precisely that on a revmaster that I have turbo charged and fitted with EFI.
