Primary Load Sensor
The factory Mass Air Flow (MAF) sensor is not used as the load input in the startup calibration
as supplied by AEM. The MAF sensor has been shown to be restrictive and, therefore, AEM
recommends using the MAP sensor as the primary load input. The factory MAP sensor will
reliably read pressures up to approximately 230 kPa (18 psig) of boost. Above this pressure, it
is recommended to use a 3 bar MAP sensor or higher (Part # AEM 30-2130-50).
Fuel Pump Control
As supplied from Toyota, the OEM ECU interfaces with a fuel pump ECU to control the speed,
high or low, of the fuel pump based on load. The AEM EMS has the ability to replicate this
functionality; however it is configured in the Startup Calibration to run the fuel pump at high
speed at all times.
The EMS Output COIL8 (Pin 22A) is used to send a 5V signal instructing the OEM fuel pump
ECU to energize the fuel pump. Configuring User PW Out to use LS8 and, for example, User
PW Analog In to MAP Volts will allow the voltage sent to the fuel pump ECU to be varied in
relation to MAP Volts/pressure. Increasing the duty cycle of the LS8 output will decrease the
speed of the fuel pump.
