An AFC and a MAFT try to accomplish the same goal but they do it in different ways. The AFC has more refined tuning points based on RPM and the MAFT has a more raw approach to tuning by using injectors compensation and 4 points of RPM tuning. I guess you could compare a MAFT to a 5 knob AFC on steroids. With the difference being that you can eliminate the stock MAF and compensate for bigger injectors with the MAFT. Obviously there are a few more benefits but you get what I mean.

The only draw back to a MAFT over an AFC is the MAFT uses bionary dipswitch combinations to adjust A/F ratio as well as different combinations for different injectors sizes. Another thing that sucks about the MAFT is that it only uses four different RPM points for tuning. Obviously with the AFC you have a few more RPM points to tune with as well as high and low throttle settings on the newer versions. I think thats the reason a lot of people use the MAFT with the AFC. You get the benefit of running bigger injectors without having to max out your AFC into the minus and you get the AFC to fine tune where the MAFT will not.

For a stock 450cc application you zero out everthing except for the AUX, that you would set to 3. I am not 100% sure but I think the new version of MAFT can compensate for up to 1200cc injectors.
