It might work on carb cars but it is worthless because there are only two kinds of carb car owners now, Collectors holding a Classic or poor as dirt driving old junkers, the collectors don't care about MPG and would not mess with a classic and the poor junker owners cannot afford a MPG device...

you need to start with the 02 sensor before the CAT. You will need an EFIE device and start with changing it to 850 milivolts. that will lean it out.. and should result in 10-15 percent in crease im mpg while supplying hho in its place. If the check engine light goes on.. turn down milivolts till it turns off.
MAP sensor would need modding if you have Knock sensors
