Sensors & Accessories
Manifold Absolute Pressure Sensor (MAP)
This sensor monitors manifold vacuum, varying output voltage to the ECU as a function of load placed on the engine, providing necessary data to control fuel enrichment.
Coolant Temperature Sensor (ECT)
ACCELL/DFI's Coolant Temperature Sensor employs a thermistor to obtain accurate measurement of engine temperature. As the engine warms, thermistor resistance decreases, letting the ECU know that it can reduce fuel enrichment.
Air Temperature Sensor (IAT)
ACCEL/DFI electronic fuel injection systems monitor inlet air temperature to provide the ECU with more accurate status of engine operating conditions. This Air temperature Sensor is a replacement for the unit supplied with ACCEL Super-Ram EFI Systems. It helps determine the proper amount of fuel to inject.
