It only needs to flow more if it is a restriction. On a stock 22RE, the AFM is not a restriction. On a modified 22RTE, the AFM can be a restriction.

Otherwise, as Darin quoted from my site, the 1982 Supra 5MGE AFM is plug and play for 1986-1988 22RTE motors, but will obviously need some tuning to work. It has also been used with 22REs from similar years. The 1983-1985 5MGE AFM can also be used, but the output signal is the inverse of the 22RE/RTE signal, so unless you swap over the 22RE/RTE resistor board, it will put out the low signal when it should put out the high signal, and vice versa. This means at wide open throttle, it will tell the ECU the motor is idling, and at idle, it will tell the motor to send enough gas for wide open throttle.

Clear?

Bottom line: unless you are making more than 160 rwhp, you don't need this mod.
