• Engine speed input.

• Boost scramble activation input.
• Transbrake bump control input.

The Cortex EBC is compatible with a wide variety of engine speed signals, and most vehicles will have several options to choose from when selecting an RPM source. The following engine speed signal types can be used (in order of preference):

• Tach signal from ECU/ECM/PCM or gauge cluster
• RPM Output from CB-2 CAN BUS SPEED AND RPM INTERFACE module
• Cam or crank position sensor
  • The Cortex EBC can interpret virtually any trigger wheel pattern with 60 teeth or less.
  • All 3-wire and most 2-wire cam and crank position sensors can be detected by the Cortex EBC without any additional components.
  • Some 2-wire sensors will require the use of a SPEED SENSOR ADAPTER or VR TO HALL SENSOR CONVERTER.
• Transmission input shaft speed sensor (auto trans applications only)
  • Some 2-wire sensors will require the use of a SPEED SENSOR ADAPTER or VR TO HALL SENSOR CONVERTER.
• Coil trigger signal from ECU/ECM/PCM or negative (-) terminal on primary (LOW VOLTAGE) side of ignition coil
  • Electrical noise on some applications may prevent the Cortex EBC from accurately determining RPM.
• Fuel injector trigger signal from ECU/ECM/PCM (not compatible with gasoline direct injection)
  • Electrical noise on some applications may prevent the Cortex EBC from accurately determining RPM.

• Vehicle speed input.
• Launch boost control activation input.
• Boost scramble activation input.
• Transbrake bump control input.

Most vehicles manufactured before 2007 will have a suitable vehicle speed signal that can be connected directly to the Cortex EBC. Some older applications utilizing VR type speed sensors may require the use of a SIRHC Labs Speed Sensor Adapter or SIRHC Labs VR to Hall Sensor Converter.

Many vehicles manufactured after 2007 will require a CB-2 CAN Bus Speed and RPM Interface to obtain a vehicle speed signal. Some vehicles can use a SIRHC Labs Speed Sensor Adapter or SIRHC Labs VR to Hall Sensor Converter to obtain a vehicle speed signal from an ABS wheel speed sensor.

The following vehicle speed signal types can be used (in order of preference):

• Digital speed pulse signal from ECU/ECM/PCM or gauge cluster
• Speed pulse output from CB-2 CAN BUS SPEED AND RPM INTERFACE module
• Transmission output shaft speed sensor
  • All 2-wire sensors will require the use of a SIRHC LABS SPEED SENSOR ADAPTER or SIRHC LABS VR TO HALL SENSOR CONVERTER.
• ABS wheel speed sensors
  • Requires the use of a SIRHC Labs Speed Sensor Adapter or SIRHC Labs VR to Hall Sensor Converter. Some ABS Sensor types are not compatible with any of these devices. In these cases a suitable speed signal can only be obtained with a CAN bus adapter module.
