The S-AFC read MAF signals from either 0v-5v or 5v-0v the protege MAF readys from 5v to 10v so it can't read the MAF signal. from what i understand, this is the reason why we can't use the apexi safc on our cars. my friend had a suggestion. would it be possible to put in a resistor box to lower the voltage from the maf? and then raise it again from the safc to the ecu? just a thought....
