Bigstuff3 GEN3 PRO SEFI DAE Option - User Manual Harness Main Connector The 30-way harness side main connector mates with the GEN3 ECU header connector marked with “DAE”. This connector will only fit in one direction, but must be mated with the ECU header connector marked “DAE”.
Bigstuff3 GEN3 PRO SEFI DAE Option - User Manual Turbo Shaft Speed This connector must interface with a two (2) wire Variable Reluctance (VR) style sensor (not a halleffect device). Calculates a 16 bit RPM with 1 pulse per revolution. Contact BigStuff3 for more information on the interface required for this input. Turbo Back Pressure This input is used to measure pressure on the turbine side of the turbo charger.
Bigstuff3 GEN3 PRO SEFI DAE Option - User Manual Input Shaft Speed This connector must interface with a two (2) wire Variable Reluctance (VR) style sensor (not a halleffect device). Contact BigStuff3 for more information on the interface required for this input. Drive Shaft Speed Drive shaft speed can be logged for boost vs. RPM comparisons and for calculating the amount of torque converter slippage. The sensor calculates a 16 bit drive shaft RPM.
Bigstuff3 GEN3 PRO SEFI DAE Option - User Manual Fuel Pressure The fuel rail pressure can be logged to ensure that the rail pressure differential remains constant. This is extremely important for turbo applications where rail pressure needs to increase with boost pressure. The logged fuel pressure data provides the user important insight into whether the fuel pump(s) is capable of maintaining a constant fuel rail pressure differential during critical boost events.
