I currently have a sohc zc and was wondering if the 88 thru 89 ecu would be better to use with it then the crx si ecu. I heard that it would make my car run rich but i also heard that it would be better because the advanced timing curves and better fuel maps and was wondering if it was worth while getting thanks for the help
