Analog inputs (voltage).

User-defined input - Mostly used with pressure sensors or other 0-5V inputs not defined below.

ac pressure sensor - Can be calibrated in any unit. Required sensor for the AC MAGNETIC CLUTCH output function.

accelerometer, X.

accelerometer, Y.

accelerometer, Z.

CAN system EXHAUST valve - Used on some OEM CAN system to control the exhaust valve(s).

CAN System Fuel Consumption Meter - Used on some OEM CAN system output data to a consumption meter (like displaying boost pressure instead).

fuel level 1 - Must be calibrated in the 0-100 % range. Used on some OEM CAN system to display fuel level in instrument cluster.

fuel level 2 - Must be calibrated in the 0-100 % range. Used on some OEM CAN system to display fuel level in instrument cluster.

CAN System Torque Value- Used on some OEM CAN system.

Crank case pressure - Must be calibrated in the pressure unit kPa.

Coolant temperature sensor - Must be calibrated in deg C. Overrides the CLT input wire and uses this input as CLT instead.

Coolant Pressure - Must be calibrated in the pressure unit kPa.

Differential temperature - Differential temp sensor.

E-throttle 1, position MAIN - Input from E-Throttle 1 position input 1 (main).

E-throttle 1, position BACKUP - Input from E-Throttle 1 position input 2 (backup).

E-throttle 2, position MAIN - Input from E-Throttle 2 position input 1 (main). <-- Only used if using dual E-Throttle bodies.

E-throttle 2, position BACKUP - Input from E-Throttle 2 position input 2 (backup). <-- Only used if using dual E-Throttle bodies.

E-throttle 1, pedal position MAIN - Input from E-pedal position input 1(main).

E-throttle 1, PEDAL position backup - Input from E-pedal position input 2 (backup).

EGT sensor 1 - 8 - Must be calibrated in deg C.

wastegate position 1 sensor - Must be calibrated in the 0-100 % range.

wastegate position 2 sensor - Must be calibrated in the 0-100 % range.

Engine oil pressure - Must be calibrated in the pressure unit kPa. Used on some OEM CAN system to display custom oil pressure in instrument cluster.

Engine oil temperature - Must be calibrated in deg C. Used on some OEM CAN system to display custom oil temperature in instrument cluster, or just used as a regular temperature sensor. If you have wired an oil temperature sensor to this input, select this.

engine compartment temperature sensor - Must be calibrated in deg C. Mostly used on Porsche vehicles, when there is a engine compartment temperature sensor mounted.

Ethanol % sensor (analog) - Must be calibrated in the 0-100 % range. Used with external ethanol sensor with an 0-5V output. (Do not use with the GM/Continental digital sensor).

External BARO sensor - Must be calibrated in the pressure unit kPa. When activated, MaxxECU uses this as BARO sensor instead of sampling the MAP sensor during power on.

External map sensor - Must be calibrated in the pressure unit kPa. When activated, MaxxECU internal MAP sensor is used as BARO sensor instead and the wired external MAP sensor is used as MAP instead.

External map sensor CAM reference - Must be calibrated in the pressure unit kPa. When enabled this sensor is used for the trigger system and the normal MAP-sensor is used for engine control. Useful for ITB bike engines with a manifold/bridge mounted MAP-sensor for engine control and a runner placed sensor for engine sync.

External wastegate pressure sensor - Must be calibrated in the pressure unit kPa. For usage with CO2 boost control.

Fuel pressure sensor 1 - Must be calibrated in the pressure unit kPa.

Fuel pressure sensor 2 - Must be calibrated in the pressure unit kPa.

Gear position sensor - 0-5V sensor to indicate the actual gear position on sequential gearboxes.

intake temperature sensor - Must be calibrated in deg C. Overrides the IAT input wire and uses this input as IAT instead.

lambda sensor bank  A - Used when an external wideband sensor electronics is wired to an analog input, selection of lambda controller is done in Inputs --> Lambda sensor.

Lambda sensor bank B - Used when an external wideband sensor electronics is wired to an analog input, selection of lambda controller is done in Inputs --> Lambda sensor.

RPM, engine (not for fuel/ignition control).

Multi position switch 1.

Multi position switch 2.

Throttle position sensor - Must be calibrated in the 0-100 % range.

Transmission temperature - Must be calibrated in deg C. Transmission temp sensor.

Pattern generator RPM.

SHIFT FORCE SENSOR - Used by the Shiftcut system.

switch decoder 1 - Switch decoder.

switch decoder 2 - Switch decoder.

Tune selector - Can be used as any X or Y axis, or even as the 4D axle in any table to select different "tunes" in the whole system.

 

Note: Make sure to calibrate the sensor in the correct unit used by the system, especially if the sensors is used to control something, like fuel pressure, boost pressure, ac pressure etc.
