I've heard of an Apexi and map-ecu product being used extensively by the Supra boys to eliminate the OEM AFM. Apparently works great and converts to a speed density MAP based system. Wouldn't be hard to wire in and they apparently self-learn the output of the AFM under different load conditions. Then you just remove the AFM completely and take it to a dyno for fine tuning the fuel and ignition maps.
