so yeah ive been looking at some celica pictures and ive noticed people putting some kinda box **** on their intake. and i though it was a "boost leak finder thingy" but ive seen it on n/a cars.

heres a pictures of one.

MAPs read vaccum and and send out voltage signals which are all interpreted by the ECU. MAP equipped vehicles usually also have other sensors, such as IAT and ICV, and others. The AFM can do all of that and then some. To do a conversion, you'll need a different ECU that can read and interpret the MAP signals, in the 3SGTE's case, probably an ST205 ECU or something. You'll also need the above mentioned sensors. From there, you repin and rewire accordingly to match the ECU.

As for the AFM, it literally has a little door on the inside that flaps. The flapping triggers different voltage signals and such to the ECU. The AFM can also measure temp, density, vaccum, and other things... but it reduces the overall intake in high-powered vehicles.

yupp, what i like about the hydra-nemisis EMS kit for the MR2 (could also be used in a celica) is it includes all the sensors needed to convert away from the AFM system. or you could use a ST205 ECU as kwanza said, but you would need to re-pin the ECU and basically do the wiring yourself, which youd end up doing anyways on the swap. my feeling is if you are going to spend the time/money to do a full ST205 3sgte swap, you might as well drop the extra grand to get a fully tunable EMS.
