You can control it fairly well post combustion (smog pump) by either developing your own control unit for a smog pump/1 wire oxygen sensor so the cat could work or finding a system (I think it's called a FFS in emissions lingo) from an ~80s/90s engine of similar displacement and retrofitting that. Given all the work involved I think a conversion to TBI w/ megasquirt would be easier, cheaper, and also improve mileage.
